I'm looking forward to the 175gr Tipped GameKing (TGK) out of a .270 (Win?) test, too. Thanks for doing this & posting your results.
The 270s are getting shot out of a 270/338 RUM improved wildcat. Left to right is a 270 Win, 270 WSM, 7mm Rem Mag, 7mm Weatherby, 27 Boondoogle.I'm looking forward to the 175gr Tipped GameKing (TGK) out of a .270 (Win?) test, too. Thanks for doing this & posting your results.
I haven't yet on this round of testing but I did previously in some other testing I did. I'll probably try and do that some of the bullets that I have a good supply of. Shooting reduced loads at mid range made some of the bullets appear questionably stable and not perform well. Any low impact velocity tests I do this time will have to be at extended ranges to give all the bullets a fair chance to perform.Yorke--any chance you done any tests with the impact speed being @ 1800 fps? And if so, did the bullets stay in or exit?

It's a bit bigger than a 270 Win. LOL
The interesting test with the 270 is that I have one barrel that's an 8.5" twist and a second one that's a 7" twist. The goal is to see if there's a difference in how the bullets behave from the different twists.

When bullets aren't properly stabilized, they tend to tumble on impact. They might shoot well on paper, but they won't perform well on game. It's mostly tied to barrel twist, and to a lesser degree by velocity and elevation. I saw a lot of "banana bullets" in my previous testing when I would run reduced velocity loads in the minimum recommended twist for a bullet. I saw this more with the really long copper bullets where I'd dig out the bullet and it would have a significant bend in it instead of expanding. Berger's twist rate calculator is a great tool for getting an idea about which bullets will properly stabilize in your gun.Yorke when you stated that at mid range some of the bullets appears to be questionably stable and not perform well what do you mean and what did they do? Also what ranges and impact speeds was that?
Many thanks
I've really liked the Shock Hammers ever since they came out. The performance of the 130s from the little 6.5 Grendel blew me away. A mid-weight for caliber bullet like that to go through that much gel was pretty crazy. The length of the wound cavity and the straight-line penetration were great to see too. I'm a "two holes" kind of guy for my hunting bullets and I always like a good exit. There's no question that the 130 of that little 6.5 Grendel will exit. My Grendel is a little CZ527 with an 18" barrel that I use as a truck gun, so it gets pulled out for anything from porcupines to elk if a target of opportunity steps out while I'm cruising the logging roads. I'd be comfortable shooting pretty much anything with that load inside of 200 yards, which is a long shot while driving in the timber.Wow, that represents a LOT of work - especially of interest are the Shock Hammer results - fascinating stuff. Thank you for sharing your process and results, you are a credit to the community, sir!
I already have a handful of the 30 cal bullets tested, I'm just waiting until I can get a few more done this weekend before I post everything. Here's a teaser though:Looking forward to the 30 cal 124 hammer test! Thanks for all the work! Very neat!
