Pushing Berger 7mm Berger 168s or 180s??

[royinidaho]

Anyone out there with any experience, besides Kirby, pushing the 7mm Bergers well beyond 3300 fps?? Regular and/or "Thicks"???? I'm off on one of my wild goose chases.

I've done a small amount of work with my 7mm RUM with the 180 Berger VLD.
3007fps is the sweet spot with my rifle. As I worked up in velocity, groups increased as well as the velocity spread between each shot.
I'd talk to Earl Fouracre here on the forum.
He built a 7 RUM shooting those 180's close to 3400fps out of a 30" Pacnor.

Thanks Gamedog, I'll check with Earl.

7mmrhb will be pushing them that fast very soon. Gun is ready, but weather and owner aren't!

ah, this is good!

Of course I'll want all the details, good, bad, indifferent. Velocity, twist, chamber, throat and especially the measured gravity at the location your are shooting.

A my next weird project hinges on your success or your lack there of.

That's a bummer. I push the 180's close to 3000 out of a standard 7RM. When I burn the thoat out I will Chamber to stw to get the max life out of this barrel. Then probably 7mm/338lm.

Could 7mm/338 Lapua AI do 3400-3500 with 180 Bergers? That would be a laser beam for a couple hundred rounds!

Or get those new 180 grain .308 HATS and do 3600 fps with a .711 BC in a 30/338 Lapua AI...giving me wild ideas!
