24" barrel, Federal 210M primers.

If 42 gr of H4350 is maximum with a Barnes 120 TSX, and only produces 2780 fps out of a 24" barrel -- a different powder choice is definitely in order!

2900+ fps is very easy with Re 15 and H 414, out of a 22" barrel, without undue pressures. Each rifle is a law unto itself, and you have to work up, and all the standard caveats. But I would never trifle with H4350 in a 260 Rem if that's the best it can do.

The only way you can empahticly say a load can be over book max and still be under pressure is with a strain guage.

Any other method is just a guess. You can mic it, look for flattened primer, shinny spots, loose primer pockets, sticky bolt lift, whatever, it is still a guess.

Whether or not another powder should be used....maybe.
