280 rem loads using imr3031
I have a 280 I inherited from my dad it was made By gilbreath in Stephenville Texas. Whoever had it made had the chamber length set up for factory loads...I have been trying to work up a load using 140 grain Ttsx Barnes bullets and 4831 powder but I have to seat them so deep that I can't get more than 52 grains of powder in them. It is just starting to tighten the groups up. I found some loads using 3031 but not for Barnes bullets only spritzer type..is it safe to use these loads with the longer bullets?
