Well I have friend that has worked me up 2 loads loads for my. Ruger M77 28 inch barrel rifle. IMR 8208 shoot 2436 fps with 140 Serria matchking hpbt and shoots 1/2 inch groups at 200 yards. Crazy accurate. Then 2nd load H4350 2816 fps will shoot under moa through 200 yards at are rifle range. I was able to get this ammo loaded so cheap I could not pass it up because he sold his 6.5 creedmoor and now shooting 338 Lupa and want to just get read of all his components. We reloaded 500 rounds of the IMR 8208 and have about 200 rounds of the faster h4350. Question... what scope and reticle would work best for me if I wanted to switch back and forth from fast shell to low speed shell. Do you think I should just use moa dots or turn turrets when changing ammo ? And what scope to buy with what reticle. Want to shoot out to 1300 yards. the slow shell IMR 8208 still does excellent at 1000 yards. Thanks. Marty
