All trimmed to 2.485" with a light bevel in and out........
Using IMR 4895 in the 1903 bolt action. (no Garand)
Never shot a FMJ out of this rifle before......... !!
I started with 46 grs that several manuals called out for 2600 - 2700 fps........ but I got 2465 fps without a crimp on the case.
Near maximum load w/o a crimp hit 2703 and all these loads were at 2.17" or over at 100 yards
I did have one load that I crimped with 27 grs of 4895 and it hit 1.5" high but did put the four test loads into a .68 grouping.
Only bad thing is I did not chrony this load.
The question now is, should I retest the 46gr and 48gr with a crimp ..........and waist bullets and powder ..........or should I be happy with the .68" load ?
Can the FMJ w/c bullet do better at lower speeds..... higher speeds, for target use? I am guessing that the 27gr load is doing around 2580 +/- .
I have had this powder up to 52grs in commercial RP brass but
49.5 grs was best accuracy in the high end target range with hunting bullets.
Ball M2 ammo hits 2700 fps in GI cases......... do I need to go this high or is there a "Target speed" that works well with this bullet.......... in general per all those major target matches.
Thanks for any info.
