Beautiful morning for some ammo comparisons in the FN SPR.
Enjoy this time of year. Using 4 different loads today in the FN SPR. I found all within usable range for 100 yd precision. 10 round groups all fell within 1" bullseye starting with cold clean barrel for each set. After a few years of experimenting, load development has produced similar poi which makes things much simpler for my short range calculations.
Load 1. 136 gr fb custom in DAG case, Tula berdan lr primer, 45 gr Varget, .5 moa at poa.
2. 136 gr fb custom Win case, 210m primer, 42 gr 4895, .5 moa at poa.
3. 136 gr fb custom DAG case, Tula berdan lr primer, 45 gr 4064, .5 moa at poa.
4. 168 gr smk RA 68 case, 41.4 gr 4064 .5 moa down 1/4" from poa. 1 click up on MK4 and group is right with the others.
