[QUOTE="docopac, post: 242083, member: 13592"] Just remember though that what may produce tight groups for some rifles may not work as well in your rifle. What I do when I get a new rifle is load 3 rounds each of differing powder charges in 1/2 grain increments. Then I place a target at 25 yards and shoot the 3 rounds at it, then switch to another target for the next 3 rounds and so on and so on. You will see your groups get smaller as you aproach the optimum charge for your gun and bullet weight that you have chosen. Then you will see the groups get larger again as you leave that optimum charge. This narrows it down for you but now you start over and load from the 1/2 grain below what looks like the optimum to 1/2 grain over the optimum charge in 1/10 grain increments and go back to the range and do it all again. This time the spread in groupings won't be as pronounced but try to pick the best one and load some bullets. go to the range again and sight in at 100 yards and see how tight you can hold your group then move out to 200......300.....+ what ever you are wanting to shoot at. Keep in mind that different powders may also influence the groups. as has been stated here Varget and IMR powders are both good choices. Get yourself a reputable loading manual from the bullet manufacturer you wish to use and approach the max loads with a great deal of caution! look for presure indicators as you work your way through the loads and if you see signs of over presure stop and disassemble the higher charged bullets ASAP. I hope this helps. Doc [/QUOTE]
