Thanks I Will look for his postings on that.You can find postings from Mike Turner on this site. He's the guy to talk to.
Tanks I’ll look him up.A guy called Michael Turner did very well shooting a 30/30, he even made is own projectiles
Do a search on the Accurate Shooter website a lot of info about Michael there
DONT....it ain that simple you will likely be very disappointed. Talk to mike first he bought a ton of 30-30 cases, selected the best, THEN went to work on them to make the useful..machined the face of the case head. neck turned of course. not sure what else..it might be in the history here,..but may have been lost. he lives in new mexico. i stopped by and saw him a couple years backFrom what I have read so far, written by Turner, is mostly in the sporter category, unless I misread. Since it is a rimmed case and supposed to be able to handle pressure as good as BRs, next project Will be to get my hand on a 1:17 custom barrel, get it chambered for 30-30 , fit it on a bolt action and try it at VFS 100 yards with bullets in the 110-120 grains. I have Faith it might be a good shooter . Competing buddies Will probably think there is something wrong with me. Never know … Might work out good.
Are you going to spec the reamer to headspace on the rim, the shoulder....or both?Since it is a rimmed case and supposed to be able to handle pressure as good as BRs, next project Will be to get my hand on a 1:17 custom barrel, get it chambered for 30-30 , fit it on a bolt action and try it at VFS 100 yards with bullets in the 110-120 grains.

No experience on precision shooting vs 30-30, don't know. M. Robinnett wrote: GREAT CARTRIDGE!! Head-space ON rims: face rims for UNIFORM <0.0015", turn necks, and, "never look back"! For 30/30, "shoulder be damned" - no H.S. required.Are you going to spec the reamer to headspace on the rim, the shoulder....or both?
If you're interested in more case capacity, both the 30BRX and the 30GT have a lot to offer. The GT based case woulg get you a true 30X44. You could also make the case for a 30 Dasher, now that Dasher brass is available..... the more I think it will more trouble than carrying on shooting my 30BR.
