Re: New 6.5 Idea

Save your self time, go with a 6.5 saum. Don't go with a tight neck. Get a Wyatt ex box and you can run the Berger 140 out of it. You can get 3200, but they shoot best around 3100..

This I believe! I can get 3200' out of my case with a 26" barrel and it has very close to the same capacity (probably slightly more).....Rich

Re: New 6.5 Idea

seems to me a Mr. Jim Sloan proved that you can shorten a case, reduce the taper, seat the bullet out and have similar velocity offa the same case........

I like your idea and can't wait to hear more info/data etc.... keep it coming !

Re: New 6.5 Idea

I agree if you want to spend all your time working cases. Just saying keep it simple, and the 6.5 saum will work in a short action.

Re: New 6.5 Idea

I agree 6.5 saum is a good option and I also agree that if you do not enjoy these challenges you would be nuts to try them. Remember though we are taking a run at making a efficent burning cartridge designed around 6.5-140 VLD in a std short action, not just trying to throw 140's at 3200 FPS that would be to easy. When we did the drawings we elected to stay with std magazine box length first if that is not quite what we need then we have the Wyatt,s option and .110 more room, but as you will see from the cut out pictures (I didn't get post yet) we don't have much bullet in the powder column. Worst case is we spend alot of time and money and have a cartridge that won't keep up with a 6.5-284 I've done worst.
Got the stock repainted last night should have pictures and I,m hoping a velocity ladder before to long.
Thanks for all the comments I like to here what others are working on out there.

Re: New 6.5 Idea

JWING, as Steve said we are not looking for a bigger faster case, that's easy!! I believe as others have stayed in this thread that shortening a case allows you to get to a better burn rate in powder options and increased efficiency. Instead of having 50 gr. in a 64 gr case you can get to 47 gr. in a 54 gr case.

BY the way I do brass prep as part of my job each day. I have trued the case heads and turned the necks on over 26,000 pcs of brass in the last 17 years so it's not about the wasted time for me.It's just a fun, fact finding project, not a commercial project.
