Looking to develop a load range load for hunting. Tikka T3, 300WSM using RE17 and berger 168 & 185 VLD hunting. last night shot 3 shot groups with 61, 62, 63, 64, 64.5, 65, & 65.5 grns powder. 5 minutes between shots (barrel felt slightly warm). Started last night using my bipod & rear bag. First time shooting with either. Best group so far was just under 1". Unsure if it may be affected by my novice status on the pod & bag. Thinking I should borrow my buddies leadsled for development, and use the bipod for my practice after I find my load. What size bipod are you guys using? I have the 6-9 swivel Harris, and I sure feel contorted trying to get on the scope while prone.
