"I finished up an 18\" barreled .338 ARSM(AR short mag.) and stopped by the range for the first shots this afternoon.\nI had loaded up Sierra 215gr SBT with 335, 3031 and 322 so I shot those through the chronograph and it really hit close to what Quickload had predicted. H335 was the fastest at 2484fps and NO signs of pressure.\nThe Sierras have a BC of .477 and were as accurate as I remember, 1 big hole at 50yards since I was just getting on paper and checking velocity.\nThe Barnes TSX has a BC of .437 I believe and should break 2600 easily so they should be a hog stopper like no other.\nThe upper was built using Olympic parts and that makes it kind of expensive compared to most uppers I can build.\nI'll try some more loads this week after I get caught up on orders.\n The 6.5ARSM is next and may be built on the new platform."
