Today I chronied a bunch of loads in both .223 and .308 and they were all at least 100 fps slower than expected. The one that really had me scratching my head was 155 Palmas over 45 gr of RL15; yielded about 2650 fps. This is crazy, as I expected at least 2800, from what my shooting solution was revealing last session. Anyway, does this velocity sound super slow to you guys? This was out of an SPRA1a w/ a 20" bbl BTW.
