Jim...you mentioned you're still trying to find a good load for the 10 fp. Mine shoots most any bullet that I've put through it well ! I've shot Ultramax Reman. 50gr NBT....Black Hills 52gr HP.....WWB 45gr...Federal American Eagle 50gr HP,,these all shoot a one inch group at 100 yds.
Now on the reloading side of things,, I've used H4895,,IMR3031,,Varget and Benchmark. Bullets used were 40gr Vmax,,50 Vmax,,50 Rem HP,,55 FMJ (unknown brand) also tried some Sierra 50gr Varminter and Hornady SPSX in 50gr.
Of all the above components the vmaxes shoot consistantly best,,and right around 25 grains of any of the powders. I use the Hodgden and Hornady manuals and stay within their specs.
I was very surprised at the groups I got from the 40gr vmaxes because of the 1 in 9 twist.......some groups were one ragged hole.
Hope you find something to your and your rifles' liking.
