Thread: 260 Rem, AI & Imp

If I was that guy the 260 wouldn't be my best bet. I'd go 284 and use 140's all day long.

My .260AI has a 22" barrel and I would say 2800 will be max with 140's, I have some 143grn on order to try but if you want higher speed then I would go for something else.

Yep.

I can get just under 2800fps with my 6.5x47L (140amax/Re17/24")

142gn LRAB 3007fps 24" 260AI

My barrel at 24" can produce some speed but It has a sweet spot running it slower so I don't see the point fussing around with it when it is just a bit extra wound on the turret if needed.
Don't think I have a fast barrel especially when there are standard .260s out there running the same speeds I get or faster.
I like the caliber but would have been just as happy with a standard 260 or even better a 6.5-06

What speeds are you getting out of yours comfortably?

If you want 3000 at low pressures with a 140 out of a 6.5, you only got one option... have a look at a 6.5 SAUM.... (6.5 GAP 4S) with ADI2217 (H1000)....

Everything else runs smaller capacity and higher pressures, which appears to be more destructive than capacity alone... the penalty of course is around 60 grains of powder in that larger case...

Its funny but we may yet see a move back to larger capacity and slower powders to duplicate what we can achieve with smaller capacity and higher pressures for less fuss and bother and a longer lasting barrel... not to mention a larger safety margin...

2950 with both 130 and 140 gr projectiles.

My 6.5-06 did 3100 easily with 140 gr bullets.

Sorry wasn't meaning calibre I was meaning case capacity, which would apply through the calibre choices...
