I have had good success with 100gr bullets for c,p,t, and 120gr for the ram. I use 24gr H322 in an xp100 for UAS and in the same xp, for S-U 19gr 4759. The xp is braked so I can use the rifle scope and not get rapped in the teeth. The h322 load gives a bit over 2000fps; the 4759 load generates about 1950fps. In the 10'' TC barrel I have used the 120gr for all targets with 25gr RL-7 for about 1700fps.
There are many good loads for the 7-tcu. Many will recommend 24gr H/IMR 4895. Accurate Powders markets their 2495 which is a clone of 4895. Accurate 2015 can be used as well with appropriate charges. rp
