Here is a comparison of the Sherman Short Tactical cartridges running at or near top velocity using the flattest shooting bullet combos which might be used in competition. You can draw your own conclusions to other chamberings or for hunting applications. These chamberings are all under 2.9" coal.

Rich have you run the 147 or 150 sie in the 6.5??
Yes .I shoot the 147's a lot. They run at 3117 very well in my sst and around 3200' in the SS. The 150's will run about the same because of their bearing surface

Hmmm, I believe there once was a man that repeatedly stated that a heavy high BC .257 caliber would whoop up on a 6mm 110, and a 6.5mm 140, and you just proved that all the way out to 1000 yards... :cool:

You basically just disproved the thought lines of the entire bullet market "geniuses" for the last 30+ years that refused to bring .25 cal technology up to everything else.

Thank you for proving that Rich. Vindication by hard evidence is a very sweet victory indeed...Especially for us 1/4-bore shooters. :)

Also, I think we should make a .257 Shermanized (low taper, shorter neck, 40º shoulder) version of the 6.5 Grendel with the 131 ACE for LR varmints and deer hunting, and target shooting with excellent barrel life. Ballistically it should be far superior to the 6.5 Grendel with the 130 and heavier bullets.

If you do, I'll be more than happy to rebarrel my 6.5 Grendel DMR for testing. I got all the right powder and stuff. All I'd need is a new barrel chambered in the new cartridge, but headspaced for a 6.5 Grendel type-II bolt (.136" headspacing). ;)

This is true (currently) but if Blackjack can make a 131 at .339 b.c., they can make a 140 in 6.5 at .350!!:D

Is that actual dope or are those numbers from a balastic calc?

Good timing for this thread. Waiting on parts for a 6SST and a 7SST. How does the 7mm with a 180 Berger compare to the other SST?
