Re: Who is all using a 7mm RUM?
I shoot a Pacnor barrelled 7MM-UM as my long range deer rifle. I live in Kentucky, so by long range I mean 500 yards max. I shoot handloaded 140gr BT's pushed by IMR 7828 89gr barrel lenght is 27 + the Vias muzzle break. I get about 3425 fps, with one hole 3 shot groups at 100 yards, and 1/2" 3 shot groups at 200. My longest shot on deer has been a 409 yard 10 pointer, the BT performed well.
I did try some 120gr Barnes tripple shocks, with a wide variety of powder, with less than satisfactory groups, around 3/4" at 100. I was limited to my magazine length, and did not play around with the seating depth very much.
