6.5 Creedmoor velocity in shorter barrels

[Buttermilk]

For those of you with 6.5 Creemore specialty pistols, what are you getting for velocity with 140-143-147 gr bullets with barrels in the 15"-18" length range?

Thanks

17-18 inch barrels with 140's: 2476-2550 fps

Thanks Ernie. About what I expected.

I've got a 7mm-08 XP and was considering rebarrelling it to 6.5 Creedmoor.

I may very well keep it a 7mm-08. Ballistically, I'm getting 2650 FPS with 150gr ABLR bullets (StaBall 6.5 powder) and a 15" bbl, so that puts it in the same ball park out to about 600 yds.

This was with factory ammunition.

I have a 15" 2008 in 6.5 CM. With an upper-mid range charge of StaBall 6.5 I get 2480fps using 140 grain bullets. I'm running around 43 grains. The design of the handgun I have causes it to pierce primers below book max for most high pressure cartridges, so you should be able to get more with an XP.

I'd keep the 7-08 personally.

I'm at 49.0 gr StaBall 6.5 with 150's.

I'm leaning that way. Thanks.

It's probably not worth switching. Besides the lower charge weight you won't gain much. You'll probably end up with nearly identical ballistics from a slightly lighter bullet. If you ever need to rebarrel it might be worth considering, but I wouldn't swap it just until then.
