[QUOTE="Jcann, post: 3352940, member: 33119"] [USER=15054]@swampratt[/USER] is correct and you don’t need better dies or an arbor press to create accurate ammo. First off stop changing seating depth for now. You should first work towards what is called and optimum charge weight “OCW”. Basically make 5 loads with the same powder charge and bullet seating depth. Create 5 more by adding 0.3 grains to those 5 and so on and so forth. Example 5 rounds w/42.6 grains @2.267” cartridge base to ogive (CBTO) 5 rounds w/42.9 grains @2.267” CBTO 5 rounds w/43.2 grains @2.267” CBTO [B]WATCH OUT FOR PRESSURE SIGNS, CRATERED PRIMERS/STIFF OR HARD BOLT LIFT/PIERCED PRIMERS. STOP SHOOTING IF ANY OF THESE OCCUR [/B] Load up about 5 different total charge weights and shoot them. Hopefully you’ll be able to find one string of fire that shows promise. If you do, now you can start trying to fine tune it by adjusting seating depth. I usually start out with my CBTO set to kissing the lands and I’ve never had to reduce this length more than 0.002”. But remember this, there is no substitute for a good barrel. [/QUOTE]
