I am with Ackleyman. I have a RL-19 load, with the
bullet seated .050" off the lands, for my Tikka M695,
in 25-06 Rem. Barnes TSX bullets like to be driven,
so you definitely want to push the loads up to early
signs of pressure, and often times the last, and best,
accuracy node is close to the maximum safe powder charge
for that rifle.
I will add that you will want to work these loads up,
near the temperature range you will be hunting them.
I worked my 100 gr. TSX loads, with RL-19, up at around
50-70 degrees, and had consistent sub-MOA results.
When I checked zero, on the rifle, in 20 degree temps,
which I would be hunting in, the groups had opened up,
to about 1.5 MOA, because the colder temps had lowered
the efficiency of the load, to where it had retreated
slightly from that warmer weather established accuracy node.
1.5 MOA is plenty fine for the big game hunting, at the
ranges I shoot(400 yards, or less), so it isn't much
of a concern, but if I want to get back to sub MOA, I
am going to have to re-work the load, at 20 degrees.
So have you tried RL-19, with the 100 gr. TSX bullets?
