Performance Analysis

Performance Analysis

The Raw Hammer Solid Black was Hammer’s pitch to the first-reactive-ball buyer, and the spec sheet shows restraint in all the right places. The symmetric Raw Hammer Core runs a 2.53 RG with a .038 differential: the RG keeps the core from revving up too early, and the differential sits below the balanced range, which means modest track flare and a smooth, controlled shape rather than a hard angular move. That is precisely the geometry you want under a newer bowler, because the ball does the same thing on every shot and small release inconsistencies do not get amplified downlane.

The Juiced Solid Reactive coverstock at a 3000 grit finish is the interesting half of the package. Solid covers normally signal early traction, but at 3000 grit the surface is smooth enough to preserve length, which is how this ball earns a 7 length rating despite the solid formulation. On the medium-light oil it was designed for, the cover picks up the lane gently in the midlane and flows into a mild backend, rated 5, with no skid-snap surprise. Hammer’s own series videos position the Raw line exactly this way, as a beginner platform built for predictability first. The 4 hook potential and 4 overall score say the quiet part out loud: judged against modern mid-performance equipment, there is not much total motion here. Judged against its actual job, teaching a hook release, the gentle shape is the feature.

The ceiling is real, though. On heavier oil the mild cover and low-flare core simply run out of traction, and the ball will push and hit flat.

Who Is This Ball For?

Beginning bowlers moving up from plastic or a house ball are the entire design brief. If you are learning to throw a hook, the Raw Hammer Solid Black shows you cause and effect clearly: a better release produces visibly more motion, and a bad shot does not careen unpredictably. The 10 to 16 pound weight range covers youth bowlers and lighter players, and the predictable motion makes it a low-stress strike ball on dry to medium-light house conditions. Casual league bowlers who bowl on burnt lanes late at night will also find the controlled shape usable long after stronger equipment becomes a handful.

Anyone past the beginner stage should pass. The cons are unambiguous: limited hook for advancing players and genuine struggles on heavier oil mean this ball gets outgrown rather quickly, and that is by design. Since the Raw Hammer Solid Black is no longer in production, the realistic route is the used market, where it tends to be an affordable find. As a first step into reactive bowling, it still does the job it was built for.

First off, when is the last time you have seen a black solid not roll well? You haven't - That doesn't happen. That said, Take the Juiced Cover - A Proven cover from many recent Hammer Releases and put it on the Old Raw Weight Block and then Introduce it in the Lower Mid Performance, Upper Entry Level Price Point - That's Crazy!! The Black Solid is So Smooth, It's has a nice arc and go through the pins with ease on hose patterns and drier / lower volume conditions.

As soon as this was announced I was so excited! Loved the Doom series and now throw an updated cover I’m all in! And I tell you this ball so don’t disappoint! This will rival any product in this price point! Huge performance for this price point! Great all around motion and strength!!

Here is my take on the new Hammer Raw Black Solid. The Hammer Raw Series comes in 4 models-1 solid, 1 hybrid and 2 pearls. This review will focus on the Raw Black Solid. This Raw features a medium RG/lower diff. symmetrical core wrapped by a Juiced Solid cover. The factory finish is 3000 Siaair. My “vitals” are a 405 rev rate with a PAP of 5 9/16 over and 1/8 up. I drilled mine with a standard 40 x 6 x 25 layout and have thrown it at box surface on THS and modified THS. The new Raw series adds a much needed drier lane option within the Hammer line of equipment. In terms of ball motion, the new Raw Black Solid reminds me of the Hammer Ruthless. Indeed they have the same coverstock and similar symmetrical core numbers. The Raw Black shows medium length down the lane with a smoother more gradual down lane motion. This piece is definitely best used on medium volume patterns and on patterns that are medium to shorter in length. Compared to the Pearl Raw, this puts the bowler several boards to the left. This is not a ball for heavier volumes of oil. However, this again gives the bowler a nice option in the Hammer line to get on top of the dry and not see early ball reaction. This ball might be particularly effective for certain THS where the bowler with stronger equipment is forced too far to the left. This may be an effective benchmark ball on some wet/dry patterns as well. See your local proshop for more on the new Raw series from Hammer.

I used a 65 x 4 1/4 x 25 layout, which put the pin above my ring finger. I’ve tried this ball on our house pattern, cheetah, and Atlanta oil patterns and the ball gives me a consistent and smooth reaction off the break point. I would say it’s about 3 boards weaker than my Web Tour. I have found this ball to be a great step down ball from my Obsession Tour and an amazing deal at the price point!

Mike R Jul 27, 2021

My Hammer Raw Solid is drilled 55 x 4.5 x 30 and this baby is a monster! I have yet to try this ball on a sport pattern, but this ball is now my first ball / go-to immediately on a house shot or league. I kept the surface as OOB and this ball allows me to keep my angles in front of me on a fresh house pattern! I can't wait to try this ball with some more surface and see more versatility.
