Re: 7X57 bullet choice

G'Day Fella's,

I was talking with the Australian agent www.totallyballistics.com.au for www.gscustombullets.co.za the other day, and he was saying how he was safely pushing 120grn GS Custom(GSC) bullets (a 120grn 7mm Hunting Bullet), at 3200fps out of his 7x57 rifle!
I told him that I can only safely push 120grn Barnes X and 120grn Nosler Ballistic Tips (both Moly coated), to 3350 out of my 24" barreled 7mm Rem Mag!
Apparently this has a bit to do with the GSC design of the bullet and it's ease of starting into the lands of the barrel, when compared to most other bullets!
And no, the GSC bullets, are not made under size (for caliber), to achieve this!

Because of this GSC bullet trait, it does require the use of slightly faster powder (than usual for the same combo), to achieve these higher velocity results!
That kind of tinkering is never a problem for me, just some more fun trying to get some amount of "Free Speed"!
Can't wait to give them a shot!!!

Hope that helps

Azone, has anybody told you, you look like the actor Russell Crow?

Doh!
