Sierra Game King

In my experience, weight retention is not their thing. While they hold together better than a cheaper cup-and-core bullet (think Winchester Power Point), they are still subject to the same laws of physics. Back in the 1990's I settled on Hornady spire points as a better hunting bullet over the game kings. The Sierras consistently shot better, but the Hornady bullets shot well enough -- and I have yet to have a spire point come unglued in an animal. I have, however, retrieved a couple game king jackets that were missing their lead cores. That said, I certainly did not shoot enough game animals with the game king bullets to have a statistically valid opinion on this.

I agree with most of that, except the part about Game Kings having better weight retention than Winchester Power Point. In my experience they are similar but the GK is more prone to core/jacket separation. I'd take the Power Point over a Game King.

I'm actually struggling to get them to shoot tight groups...

I'm not wanting to get too hung up on them though, as I got them cheap , they can proberly plink an I'll use a SP for hunting..

Maybe the model 70 is favouring heavier projies as not having alot of luck with 130 Corelokt or 140 sgk loads..
But it shot Supreme Accubond CT factory 140 into an inch.

An is fairly consistent with 150 flat base.


Combination of heating up barrel and maybe seating depth
