I shot 4-5 times a week at varying distances. To be honest, I didn't find it all that difficult to get consistent groupings. I have limited myself to 40 yards just because it's my first season and I'm sure target panic will come on like crazy with big game in my sight.
haven't gotten into any elk yet (they all literally hang out and bugle like crazy on private land right outside my public land spot... so frustrating lol). I'm headed up for the next few weeks for mule deer and grouse.
