[QUOTE="CaptnC, post: 1339491, member: 101755"] I'm far from an expert...FAAARRRRRR! But did you really do justice to the larger capacity cases with that short of a barrel? I was reading some "stuff" on another site where they were trimming a barrel in one inch increments and there are a lot of calibers that would do better with barrels a lot longer than the factory cut. The two that stood out was the 7.62x39 (because I was actually looking for that one) and the 6.5 Creedmoor. 7.62x39 was designed for 16" barrels (AK-47) up to 20" (SKS) but the best velocity was from a 21" or 22". The 6.5 Creedmoor was best velocity was 27". In your above data I would assume there was a lot of unburnt powder flying down range that a longer barrel could have made good use of. I would like to see you run your numbers with a 28" tube just to see if any of your samples calibers really shined. [/QUOTE]
