I have had at least twelve 270’s built with best quality barrels and fitted by really great rifle builders. In a 22” barrel I have never gotten to 2900 in any 22” barrel with any of the 4831’s made since 1985. I was one of the first to work with R26 and with that powder could reach 3000.

With 130’s I have had the best luck with IMR4831 over H4350, R17, R22, IMR7828ssc. I haven’t tried R16 or HUNTER yet.

I have had a 25” and a 26” built but both were cut to 23” then 22.5” then 22”. Those long barrels were quite clumsy.
