Re: Reload 17 for 300 WSM
My 300 WSM factory Winchester with 24" barrel is shooting 190 VLd's to .5 MOA with 61 grains of IMR 4350 and they are 2.860 COAL ( .100 off the lands ) and 2.295 OG. I find this WSM likes most loads out around .100 off the lands.
This gun also shoots .5MOA with 66 grinas of RL19 with a 180 grain ballistic tip at 2.810 COAL.
Both of these guns will hold 1 MOA all the way out to 800 plus yards. This is a factory gun.
Start loads in the middle range of what the books say and work up towards max loads until you see pressure signs.
PS....my gun shot 180 TTSX at 1 MOA at 100 yards, but feel way off as the ranges got longer.
