[QUOTE="anethema, post: 1646397, member: 107059"] Hey everyone. Got a few quesitons. My dad shoots a Cooper excalibur M52 (24" barrel 1:9 twist I believe) in 280AI and I shoot a Tikka T3 lite stainless 270WSM. He is heading up my way to visit for a couple weeks and we wanted to learn to reload together. We currently both shoot Hornady Precision Hunter factory ammo with the ELD-X and they group really well in both guns. (Half to 3/4 MOA at 400 yards on a calm day). So factory ammo works well but for cost and fun we want to reload basically. Anyways the questions are: 1. Research seems to show that there is a whole whack of powders people shoot for each one, but one that both seem to say allow higher muzzle velocity and still gets recommendations for both calibers is RL-19. Just want to confirm this would be an ok choice for both of our guns? 2. The .277 bullet for me is the 145gr ELD-X and for him it is the 162Gr ELD-X. My barrel is 10" twist and his 9". Would these be ok within 500 yards for stabilization? 3. For my gun, I tried to measure the lands but they are WAY fuckin out there on the Tikka. As in I couldn't even properly crimp the bullet in the shell if I did 0.050 off the lands, never mind fit it in the magazine. So the jump is going to be huge. Now the factory ammo seems to shoot under an MOA but I've heard that large jumps are less good on secant ogive bullets like the ELD-X and it is better to use tangent ogive (like say a Barnes LRX) when there is a big jump. Any thoughts on this? Thanks for your help everyonne. I'm not quite a long range hunter (most of my shots are in the 300-400 range) but this is a great forum so figured you guys would know your ****.
