When I worked up the 100gr loads in my 25 I started out using the Nosler BT. I found that with an AOL of 3.250 it would basically shoot through the same hole. After shooting the first couple of deer with that bullet I wanted something which didn't damage as much surrounding meat so I tried out some 100gr Partitions, and the Barnes X. Since I had been shooting the BT I simply switched the bullets and nothing else. The load wasn't max so I wasn't worried about the pressure issues. I found that using the same setting on the seating die, both the other bullets also shot into less than 1" groups as well only in slightly different impact areas. However the best part was that they all shot into less than a 2" group at 200yds which was plenty good for me.
I tried several powders when working with them all through the years but the best I found for my rifle was IMR-4831 with the 100gr bullets. The only other 100gr that did not shoot well with this powder was the Sierra which like IMR-4350. As for the loads I can't give data on them as I am not at the house, but do know it was somewhere between 50 and 53grs respectively for all loads. I used Win, Rem, and Fed cases which all seemed to shoot equally well for hunting loads, but if I wanted the utmost accuracy I used Win.
