My M-24 shoots very well with 175mk lapua brass federal match primers and 42.1 grs of Vit-140 loaded with a 72.3mm oal. I use in 300 meters match and this is a winning load.

42.6 grains of RE-15, SRA175MK, W-W case, CCI-BR2. That works for me and probably duplicates the M118LR loading.

Hello,
I use 44.2 grains of 4064/IMR w/ Lapua Brass, 210Federal Match primers and in my 12 twist, 30" barrel, performs very well indeed out to the 1000 yard mark. Give it a try.
