So i just made a load up for my 7mm rem mag sendero 700 26” barrel..so i come up with 68gr of rl-25. Fed 215 primer. With a hornady case and a 160gr accubond. The COAL is 3.290 ..so i made a 3 shot group my vertical was great but all 3 shots where in a horizontal line. An inch from each other..any ideas on what the problem could be? Is it time to trash that load or am i close and need to do some tweaking?
