Brunswick Combat Solid Bowling Ball Review: Rampart Core + HK22C2 Alpha Premier Solid
Brunswick Combat Solid Bowling Ball: Maximum Traction for the Heaviest Volume
HK22C2 Returns to the Combat Line: The Biggest-Hooking Brunswick Ball Since the Mesmerize
By Brian Halstrom, BowlersMart Editorial Team. Specs on this page are verified against Brunswick’s official Combat Solid release data.
The Brunswick Combat Solid is the most aggressive traction piece in Brunswick’s Performance Pro lineup, carrying a 96 traction rating, the highest in the line. Brunswick calls it the biggest-hooking ball it has built since the Mesmerize. It pairs the asymmetric Rampart Core with the new HK22C2 Alpha Premier Solid coverstock, which marks the return of HK22C2 technology to the Combat line, a combination built to read the lane early and keep driving through the pins.
Where a pearl or hybrid waits to make its move, the Combat Solid is meant to go to work the moment it hits the lane. The Rampart core stores the energy and the Alpha Premier Solid cover puts it on the lane as continuous, controllable hook, giving stronger players a benchmark traction ball for fresh, heavy patterns.

The Technology Behind the Combat Solid
Brunswick built the Combat Solid for heavy volume. The asymmetric Rampart core reads the mid-lane strongly and keeps its motion continuous instead of rolling out, while the HK22C2 Alpha Premier Solid cover, finished at 500, 1500 Siaair Micro Pad, grips the oil early for a strong, predictable footprint. The result is an early, traction-forward read with a smooth, hard-driving backend rather than a sharp, jumpy reaction. The full per-weight numbers are listed below.
Rampart Core: An Asymmetric Engine Built for Early, Continuous Traction
The Heart of the Combat Solid
At the heart of the Combat Solid is the asymmetric Rampart Core. At 15 lb it measures an RG of 2.502, a strong .051 differential, and a .019 intermediate differential (mass bias), numbers that produce heavy flare and an early, powerful read. The asymmetry gives the core a defined preferred spin axis, so layout has a real say in how early and how strongly the ball revs up. Brunswick wraps the Rampart core in DynamiCore, the outer-core technology that adds durability and a stronger, more responsive hit through the pins.
That combination of low RG and high differential is what makes the Combat Solid a true heavy-oil piece. It reads the mid-lane early and keeps storing energy deep into the pattern, so it drives through the pins instead of giving up at the spot. Paired with the right layout, the Rampart core delivers strong, continuous motion that higher-rev players can control.
HK22C2 Alpha Premier Solid: A Premium Solid Built to Grip the Heaviest Oil
Brunswick Combat Solid
A Premium Solid Built to Grip the Heaviest Oil
Wrapping the Rampart core is the new HK22C2 Alpha Premier Solid coverstock. Built on Brunswick’s HK22C2 base chemistry, the Alpha Premier Solid formulation is engineered for maximum oil traction, earning the Combat Solid its 96 traction rating. Finished at 500, 1500 with a Siaair Micro Pad, the surface grips early and reads the friction predictably, giving you a strong, even footprint on fresh, oily lanes.
- Maximum Oil Traction: The Alpha Premier Solid cover is built to grip the heaviest volume, with a 96 traction rating at the top of the Performance Pro line
- Strong, Continuous Motion: An early mid-lane read that keeps driving through the pins rather than rolling out on heavy patterns
- Asymmetric Core Power: The Rampart core carries a strong .051 differential for heavy flare and aggressive energy storage
- Surface-Tunable: Keep the 500, 1500 Siaair surface for the earliest read on heavy oil, or take it up for a touch more length when the volume drops
Overall, the HK22C2 Alpha Premier Solid cover gives the Combat Solid its identity: an early, strong, continuous read for the heaviest oil, with the control a benchmark traction ball needs.

Who Should Use the Brunswick Combat Solid?
Designed for ALL Styles of Bowlers
Brunswick built the Combat Solid for stronger players who face heavy oil and want early, controllable traction. The asymmetric Rampart core and Alpha Premier Solid cover read the mid-lane strongly and keep driving, making it an outstanding fresh-pattern benchmark for higher-rev and medium-speed bowlers.
Ideal Lane Conditions
The Combat Solid is particularly effective when:
- Heavy oil volume where you need strong, early traction
- Fresh house and tournament patterns that reward an early read
- When lighter equipment is skidding too long through the front
- Higher-rev and medium-speed bowlers who want continuous, controllable motion
Player Style Fit
- Higher-Rev Bowlers: The asymmetric Rampart core rewards revs with heavy flare and a strong, hard-driving backend
- Tournament Players: An early-reading benchmark traction ball for fresh, heavy patterns where control matters as much as hook
- League Bowlers on Heavy Oil: A dependable first ball out of the bag when the house pattern carries real volume
- Traction-First Stylists: The Alpha Premier Solid cover grips early and reads predictably for players who want to see the ball every shot
How the Combat Solid Fits in Your Arsenal
Where the Combat Solid Fits in Your Brunswick Arsenal
In the Brunswick lineup, the Combat Solid is the strong solid you throw first on fresh, heavy oil. It sits at the top of the Combat line, giving you the earliest, most aggressive read in the bag. When the Combat Solid starts to look too strong as the lanes break down, step down to the Combat Hybrid, then to a pearl for more length and a cleaner backend.
Arsenal Strategy Guide
Heaviest Oil / Top of Bag: Combat Solid (asymmetric, HK22C2 Alpha Premier Solid, 96 traction) ← Perfect middle ground
Medium-Heavy Oil / Transition: Combat Hybrid (94 traction), Warning Alert (HK22 Savvy Hook Hybrid)
Medium Oil / Length and Backend: Infinity Quest Pearl, Crown Victory Pearl
Real-World Arsenal Scenarios
Tournament Player: On fresh, heavy patterns, open the bag with the Combat Solid. Its early, traction-forward read and continuous motion give you a controllable benchmark on the highest volume. As the pattern breaks down and you need more length, step down to the Combat Hybrid, then to a pearl like the Infinity Quest Pearl for the cleaner backend.
League Bowler on Heavy Oil: The Combat Solid is your first ball out of the bag when the house pattern carries real volume. Once the lanes transition through later games and the Solid starts to look too strong, move to the Warning Alert or a pearl for the wider angles you will need.
Higher-Rev Stylist: The asymmetric Rampart core rewards revs with heavy flare and a strong, hard-driving backend. Keep the 500, 1500 Siaair box surface for the earliest read on heavy oil, then take it up a touch for more length when the volume drops.
Ball Maintenance & Care Guide
To maximize the performance and longevity of your Combat Solid, follow these maintenance guidelines based on Brunswick’s official recommendations:
Suitable Cleaners
- Wipe the cover with an approved reactive ball cleaner after every session
- Deep clean periodically so the Alpha Premier Solid keeps reading the oil consistently
Pro Tip: Solid covers absorb oil over time, which softens the read. Wiping the Combat Solid down after every set and deep cleaning it periodically keeps its strong early traction consistent over the life of the ball.
Suitable Polishes
- Keep the 500, 1500 Siaair surface fresh for the earliest read on heavy oil
- Take the surface up for a bit more length when the volume drops
Surface Adjustments: The 500, 1500 Siaair Micro Pad finish is a traction setup out of the box. Raise the grit for more length when the oil drops, or refresh the box surface to restore the early read. Have surface changes done at your pro shop for an even, consistent finish.

Frequently Asked Questions
About the Brunswick Combat Solid
The Combat Solid is the most aggressive traction piece in Brunswick’s Performance Pro line, carrying a 96 traction rating, the highest in the line. It pairs the asymmetric Rampart core with the new HK22C2 Alpha Premier Solid coverstock, which marks the return of HK22C2 technology to the Combat line. Brunswick calls it the biggest-hooking ball it has built since the Mesmerize. It is engineered to read the lane early and keep driving through the pins, giving stronger players a benchmark traction ball for fresh, heavy patterns.
It is built first for hook and traction, but with control in mind. The asymmetric Rampart core and Alpha Premier Solid cover read the mid-lane strongly and store energy deep into the pattern, so the ball drives through the pins instead of rolling out. The result is an early, traction-forward read with a smooth, hard-driving backend rather than a sharp, jumpy reaction, which is exactly the controllable strength higher-rev and medium-speed players want on heavy oil.
Both share the Combat line DNA, but the Solid sits above the Hybrid in strength. The Combat Solid carries a 96 traction rating, the top of the Performance Pro line, while the Combat Hybrid sits at 94. With its full solid Alpha Premier cover, the Solid reads earlier and grips the heaviest oil sooner. As the lanes break down and the Solid begins to look too strong, the Combat Hybrid is the natural step-down for a touch more length and a cleaner backend.
Brunswick maintained the reliable Combat core dynamics, but this version reads the lane earlier and is stronger throughout, offering even more total hook and a more continuous move through the pins. The key change is the return of HK22C2 technology to the line with the HK22C2 Alpha Premier Solid coverstock, producing a bold, heavy-rolling reaction that blends the lane and drives through the pocket with authority.
Specs, Weight, and Drilling
The Combat Solid uses the asymmetric Rampart core wrapped in DynamiCore, with the HK22C2 Alpha Premier Solid cover finished at 500, 1500 Siaair Micro Pad. At 15 lb it measures an RG of 2.502, a .051 differential, and a .019 intermediate differential (mass bias). It is available in 12 through 16 lb weights and is colored Navy, Blue, Slate, and Purple.
The Combat Solid comes in 12 through 16 lb. The core numbers are strongest in the 14 and 15 lb (RG 2.513 and 2.502, .051 differential, .019 mass bias), the most common competitive weights. The asymmetric Rampart core has a defined preferred spin axis, so layout has a real say in how early and how strongly the ball revs up. Work with your pro shop to dial in the pin position based on your PAP, rev rate, and ball speed.
Yes. The Brunswick Combat Solid is USBC approved and legal for sanctioned competition. The 500, 1500 Siaair Micro Pad factory finish complies with current tournament regulations.
Care and Buying at BowlersMart
Solid covers absorb oil over time, which softens the read, so wipe the Combat Solid down with an approved reactive cleaner after every set and deep clean it periodically to keep its strong early traction consistent. Have any surface changes done at your pro shop for an even finish. And yes, every Combat Solid purchase qualifies for our Striking Rewards loyalty program, which is free to join.
Final Verdict: The Strongest Combat Yet
The Brunswick Combat Solid is the ultimate expression of strength in the Combat series. By keeping the reliable Combat core dynamics and adding the returning HK22C2 technology in the new HK22C2 Alpha Premier Solid coverstock, Brunswick built a ball that reads the lane earlier, is stronger throughout, and delivers even more total hook with a more continuous move through the pins. With a 96 traction rating at the top of the Performance Pro line, it is the biggest-hooking Brunswick ball since the Mesmerize.
The asymmetric Rampart core wrapped in DynamiCore stores energy and keeps the motion continuous instead of rolling out, while the Alpha Premier Solid cover at 500, 1500 Siaair Micro Pad grips the heaviest oil early for a strong, predictable footprint. The result is a bold, heavy-rolling reaction that blends the lane and drives through the pocket with authority, the controllable strength higher-rev and medium-speed players want on fresh, heavy patterns.
If you want the earliest, most aggressive read in your Brunswick bag, the Combat Solid is the benchmark traction ball to start with. It is available to pre-order now for the August 13, 2026 release at BowlersMart, with always-free shipping, 60-day returns, and Striking Rewards points on every purchase.
