gerritm Posted May 28, 2013 Share Posted May 28, 2013 I found some of these and used load data from Nosler @ 22.0gr of H335 with an OAL of 2.26" running them in a Seekins upper and lower with a Loki 18" 1/8 twist barrel. I took them to the range and fired a few in a test load to chronograph and got about 2460fps as they said. Didn't really pay too much attention to group size, but they were hitting in a good group at 200 yards. Had a match and it was very windy with some shots outs to 500 yards. I thought it would be perfect conditions to try them. Fired the first couple of rounds and one jammed nose first into the chamber, cleared it and had the next one do the same. Had a mag with my normal 69gr Sierra Match BTHP and finished the stage. Never have any jams using 2.26 on my 69 to 75gr loads, 1st time ever. Took them home and checked all to make sure of the OAL and they were all good. Tried a couple after checking lengths and they jammed the same way. Any ideas on why? Do they need to have a shorted OAL because of the size? Thanks, gerritm Link to comment Share on other sites More sharing options...
