Im planning on building a super short carbine using a 2250 as the base. Can anyone guesstimate what power I might get from a standard 2250 with a 10 inch barrel?

Also with a modified valve what power and shot count am I likely to acheive again with a 10 inch barrel?

I'd expect 90% of the energy a given tune could get from the stock 14" bbl. nt - Steve in NC on Aug 11, 2011, 7:38 PM

90% ???? - dan house on Aug 12, 2011, 9:22 AM

Yup. For another example, the 2240's 7" bbl gets 80% of the ME of the 2250's 14"... - Steve in NC on Aug 12, 2011, 11:06 AM

As you say, only the barrel length info: - dan house on Aug 12, 2011, 11:24 AM

Thanks for the replys guys. - Matt on Aug 12, 2011, 1:08 PM

That's my guesstimate, Matt. nt - Steve in NC on Aug 12, 2011, 3:17 PM

Your Guestimate Was Correct - Matt on Aug 19, 2011, 1:36 PM

The biggest factor in making ME not linearly proportional to barrel length... - Steve in NC on Aug 12, 2011, 3:16 PM

Which can be calculated - dan house on Aug 12, 2011, 3:48 PM

Weirdly enough, some brave souls (okay - loonies) have actually tried. - Steve in NC on Aug 13, 2011, 6:51 PM
