NoFail Posted May 19, 2014 Report Share Posted May 19, 2014 (edited) Last year about this time I was doing a round robin test to find OAL for a 168 Amax on top of 44.5 gr IMR 4064 in Hornady .308 Win cases with BR2 primers. I am loading some up now like these and using a 2.810" OAL and will shoot them next weekend in the mountains above me. Here's the target from last year.

survivalshop Posted May 19, 2014 Report Share Posted May 19, 2014 Just make sure they fit in the mag ., you can get various slight imperfections at the bullets nose & could cause problems feeding from the mag. , but you knew that . Quote Link to comment Share on other sites More sharing options...
NoFail Posted May 19, 2014 Author Report Share Posted May 19, 2014 Yeah. They fit my Pmags & I've measured every one of them after sinking the pills. Quote Link to comment Share on other sites More sharing options...

N Jensen Posted May 21, 2014 Report Share Posted May 21, 2014 44.5 of 4064, pretty stiff load. What's your FPS? Quote Link to comment Share on other sites More sharing options...
NoFail Posted May 22, 2014 Author Report Share Posted May 22, 2014 Yes it fills up to the shoulder line. I would not go higher. It was the hottest I loaded in a string starting from 43.5 gr IMR 4064 and the 168 amax. No pressure signs all thru the OCW test. 16" barrel and I don't have velocity data. I'm bringing my PACT meter for shooting these this time and I'll inform on that next week. FWIW... JP Supermatch barrel, JP LMOS BCG & adjustable gas block Quote Link to comment Share on other sites More sharing options...
hdbiker1 Posted May 22, 2014 Report Share Posted May 22, 2014 (edited) That load sounds pretty hot, unless you're using Winchester brass. In my rifle, 42.8gr of 4064 in LCLR brass and the 168 SMKs starts to leave ejector marks. So I'm going to use wither 41.8 or 42.7. Currently 41.8 shoots .8moa at 300yds, on average with about 5.0 moa come up from a 20". Edited May 22, 2014 by hdbiker1 Quote Link to comment Share on other sites More sharing options...
survivalshop Posted May 22, 2014 Report Share Posted May 22, 2014 16 " barrel will show less pressure signs , I loaded 43.5 of 4064 in LC cases & 168 SMK's & shot them in both my 16" & 20 " bbl's. with no high pressure signs . Not all chambers & barrels will perform the same way with different loadings . Also the gas system type may have a little to do with where you can go . 16"HB., 43.5 gr. IMR 4064 , rifle length gas system Avg. Vel. -- 2567 fps ES--------- 48 fps SD -------- 18 fps 20" HB, 43.5 gr. IMR 4064 , rifle length gas system Avg. Vel. -- 2707 fps ES --------- 39 fps SD --------- 16 fps Quote Link to comment Share on other sites More sharing options...
