I have a savage 111 in 7mm rm. And my savage is 1;9. It likes 139, 140, 150 and 162's not anything heavyer. I still have some 175 sp that I am keeping around for just blasting away.
the best loads that I have found that work in my rifle are
150 grn sp 67.0 grn IMR7828 CCI mag primer (2995-3010fps) This is a very accurate load and for hunting I put a 150 grn ETIP on it in place of the 150 grn sp
139 and 140 grn sp 47.0 grn IMR3031 std primer (2735-2750 fps) this is a accurate load also but, in warm weather it heats up the barrel so I only use it in the winter
162 grn amax 64.2grn IMR7828 mag primer this works accuracy is acceptable.
For the range I neck size and seat my bullets just in enough to hold them in place and this allows the bullet to seat on the groves as I chamber the round.
For hunting I full length size and seat 10thou off the grooves.
A easy way to find your "groove" is to size and trim a piece of brass donot prime or powder it! Using a qtip lube the inside of the neck place your bullet on it then chamber it . Now measure it, then with the seating depth adjuster all the way up place this into the seat die. Screw down the adjuster till it contacts the bullet then give it a gentle twist, measure again and repeat until you get the OAL you want. I will keep this "dummy" in with each box of bullets for future referance.
I have also tried RL22 and H1000 but I could not find a load that I was happy with
