Thanks olddav, I appreciate that, I can always use more help! I've seen the article briefly but need to go back and read it in depth. Took the model 10 back out today, hot and windy. Retried a couple of the previous torque settings with different ammo, most groups 1-2 inches, seems to like the 35-30 in/lbs more with a wider range of ammo. Did happen to load up some 155gr hp that shot a clover leaf measuring 7/16 inch center to center, now if I can do that consistently!

From what I've been able to tell, it seems to like bullets around 150gr and does worse the higher I move up in weight. Match ammo is generally 168gr or heavier, and it doesn't really like it, and it does really bad by the time I get up to 180gr. So it makes me think it is a stability problem, may try some even lighter loads, will see if I can find some good 130gr bullets to work with.
