Heavy bullet 22-250 ?

[bobert]

Hi Guys.

This is my first time here. My queston. Does anyone have experience of a 22-250 using a 1-7 or 1-8 twist for heavy 70 to 90 grn bullets?

Gratefull for any help.

I've a couple cut rifled 1:8" twist barrels chambered in 22.250 with 2500+ rds thru them launching moly'd Sierra/JLK/Berger 80-90gr projectiles @3200+fps.
Loaded with 4350/RL19 burn rate powders.
Projectile is supersonic beyond 1K.

Many thanks for your reply.
I assume that since you have a couple of fast twisters that accuracy must be good.

Dans40X - I've been looking at this cartridge for awhile, but have not heard anyone talk about barrel life. Not that I'm afraid to burn out a barrel or two when its truly needed (I shoot 7WSM and 6.5x284), I would just like to know what to expect. IF 2,500 - 3,000 rounds is routine, I'm all over this cartridge, potentially its bigger AI cousin.

Running Moly'd 80/90gr VLD's at 3200+fps over 36gr of 4350/RL19 yields 2500/3000 rounds of sub 3/8 MOA accuracy.
VLD's are supersonic beyond 1K.

I haven't setback/recrowned a fast twist barrel at the 3K mark for sporter/varmint use so I can't comment on accuracy or round count potential.

I have a .22-250, but had I known at the time what a good cartridge the .22BR is, I would have chosen it over the .22-250. Or....I might have gone with a 6mmBR.
