Bluerock1 Posted November 3, 2004 Share Posted November 3, 2004 I'm loading 4.6 gr of Solo 1000 under a MG 230 FMJ. OAL is 1.260. If I reduce OAL to 1.250 what kind of FPS increase could I expect. Thanks, Bluerock Link to comment Share on other sites More sharing options...
SRT Driver Posted November 3, 2004 Share Posted November 3, 2004 When decreasing the OAL, pressure increases exponentially where, depending on the cartridge, velocity may increase slightly. Control Velocity with powder charge, not oal is the rule I was taught. Keep the OAL as long as possible for 100% reliablity. my 2c. Link to comment Share on other sites More sharing options...
Bluerock1 Posted November 3, 2004 Author Share Posted November 3, 2004 Thanks SRT I'm right on the bubble at 720 FPS average. I'll just bump the powder .1 or .2 grains. Bluerock Link to comment Share on other sites More sharing options...
