[QUOTE="30-338, post: 200010, member: 10349"] [b]Groups[/b] You need to give us more info. What kind of rifle, barrel, barrel length, what else you have tried...etc. It doesn't look like your rifle likes that load you are using!!! In fact that is so bad ,I suspect something else is affecting the groups. Make sure your scope and rings and base are tight. Check your action screws. Try some different bullets...I suggest the Sierra 300 g ...You should be able to get around 2650-2700 FPS. Working up a load is often like unlocking a mystery...You try this bullet and that powder until you get a response from the rifle. The rifle will tell you what it likes...Try Retumbo or Vihtavuori 170..stick with the SAAMI COL specs for now...you can play with COL later..stick with 3.600 for now. And watch out for pressure signs such as sticky bolt lift, etc. Loading manuals are your friends. You also need a decent Chrono to really work up the loads and later to do the exterior ballistic charts...It sounds like you might want to find someone local who has some proficiency in load development...good luck and keep us posted 30-338 Oh yeah and fix the typo re: bullet weight [/QUOTE]
