Yes. TGK has a thicker jacket.Currently shooting the 130 Gamechanger out of my 260AI and 6.5 SAUM and they shoot just well as the 130 and 140 Bergers, single digit ES and they thump out to 1,200 yards. H4350 (260AI) and H4831SC (6.5Saum).
Recently saw Sierra is offering a 130gr TMK which I am excited to hunt with. The Gamechangers are supposed to be "harder" than the TMK. Both should fare well with any large NA game.
For that rifle I would look at the Berger 135 classic hunter. Fantastic accuracy! Good speed. That being said I have killed deer with the 142 SMK and the Hammer hunter 125. The 142 SMK was an old match load with H4350 running right around 2800fps. I shot that load for matches for many years and have complete confidence from 100 out to 1300 yards, very consistent performance. However I have no long range terminal performance with that bullet.6.5 creed.
Developing a load for a new gun in the family.
Anyone have anything on these bullets
130 tmk or tgk
140 impact
Mule deer and below
600 and in.
