.30 cal bullet bc .942!!!!!!

I read the article whats wrong with the .30 caliber and it got me wondering with the popularity of the .30 all over the world someone must make a high bc bullet for it. I was right, check out GS Custom bullets their in south africa and they make extremly high bc bullets for all kinds of stuff .30 197gr .942, how about a .30 163 bc .712 their not cheap but Im pretty excited to order some and try them out

It would be interesting to see some real world results from using these. However, one problem i swith stablezing them. Like Mystic player pointed out in the "what's wrong with the 30" that once we get the the 7" twist things get pretty hairy. I wonder what twist is required to launch those BC's?

Gs customs website show graphs to match bullets with optimum twist rates. It looks like the 197gr would need 1 in 8 which puts that one out for me but the 163gr. needs 1 in 10 which is what my rifle is. I dont know if you saw their hunting bullet line they have 177gr .632 bc barnes type expanding bullet. Does anybody know if anybody is making this sort of thing in north america? Or are we just simply behind.

I read that some people shooting GS bullets had waaay more drop than the BC would lead you to believe. Don't know if they have sorted out the BC issues, but it could be a fair bit lower than .942

According to Gerrard of GS Custom, in a thread here on long range, they have the bc thing sorted out. I have just ordered some of the 177g .308's. I will post on them after I do load development and can shoot them at long range. Sometime this spring.

Perhaps Gerrard will chime in again.

Re: .30 cal bullet bc .942!!!!!!

There's an old saying that starts off, "if it sounds too good to be true . . ." This could well be the case here. I haven't seen these, but bullets this light, with this high of a BC would leave me wondering if they're using a G1 drag model. This is standard for US makers, it's a model (a series of models, actually) that was developed here in the US and may or may not be what they're using. This would be my guess. Need to find this out for sure, otherwise you could be comparing apples to volkswagens.
