I'd like to thank everyone for their responses to my last post. After giving consideration to replies both here and a couple other sites, I've decided to use the Swedish Mauser action I have but to chamber it with the 6mm Rem AI. Just a quick note, I'm not breaking down a nice model 96 Mauser. The weapon is essentially a parts gun, a mismatch of serial numbers and a questionable barrel.

My thought is a Shilen #7 28" with 1-10 twist. The load will hopefully be based around an 87 grain bullet. This rifle will only be used for ground hogs and coyotes.

Any suggestions regarding barrel, twist or bullet would be appreciated. Lastly, Does this brass have to be fire formed or does any manufacturer offer it?

Thanks again.

To my knowledge, this will be a true wildcat, therefore, commercial ammo or brass isn't available. It will be easy enough to reduce the 6.5 down to 6mm. Just use plenty of neck/inside lube and reduce in increments, turning the brass a few times while taking it down.

That's a midrange weight for the .243 bullet. I would imagine a twist of 1:10 or 1:12 would be the choice. I have a 6mm/284 with a 1:10 twist that can shoot gnats with 100 and 105 gr bullets.

onelongshot, I've had 2 6remAI build with 26" long 1/10 twist barrels for the 95/100gr bullets both good rifles.

My latest 6mm is a 243AI with Hart 27" long 1/10 twist barrel. I used their mag contour something I can use antelope walk around with and I can use it above timberline for rock chucks.

not sure what 87gr bullet your going to use as Berger/Hornady making them and Berger rec a 1/10 twist for his 87gr match VLD hunting bullet and 88gr varmint bullet.

I've shot few of the Hornady 87gr BTHP/V-Max in the 243AI getting some pretty nice groups and I'm still working up loads. I put a 1/10 twist Kreiger barrel on the 243 and I'm still working up loads on that but I've had real good luck with the 1/10t twist from 85gr to 100gr bullets. I did one 6Rem with 1/12 twist and that rifle I wanted to shoot 70/80gr bullets so never tried heavier bullets.

What I've always done is talk to the barrel guys or gunsmith and I have a range of bullets that i would use and get their feed-back vs trying to shoot every 6mm bullet weight made.

Well good luck
