I've been browsing the site for a while and finally signed up...hi everyone.
So a little background and my question in regards reloading the 100 grn e-tip for the .25-06. I loaded up a series tests with RL19 from 50 to 53 grains (0.5 grain increments) at 0.05 off the lands. Velocity was great and ranged from just under 2980 fps to 3220 (measured with a Caldwell chronograph, and they were pretty darn consistent, IIRC my SD ranged between 12-27 for the various charge weights. The downside is my groups all measured right around 1.75 inches at 100 yards. Powder charge made no difference. I know we, the gun and I, are capable of sub 0.5 inch groups as that is normal for another all copper load I have developed for this rifle. I would like to work more with the e-tips and have two questions. 1) would increasing the distance from the lands (test increments of 0.01 inches) tighten up my groups, and 2) is it still ill advised to NOT go beyond Noslers 100 grain projectile mid-load for the e-tips (I saw no pressure signs at 53 grains).
Respectfully
Justin
