210ABLR & .300 Win. Mag. ~Scotty

.300winmag · Jul 14, 2015

Finally got a chance to try the 210 ABLR out of my .300, picked a mid level charge and decided to play with seating depth first, started at 0.050" jump and did 0.025" increments up to 0.100" jump. Had given up hope after the first two groups but the 0.100" load I was pleasantly surprised with. Looks like they have potential. I've never had to jump a bullet so far before they shoot though.

Any chance someone could run QL for me to get an idea of velocity?

Thanks for the bullets Scotty! I'll have to keep tinkering with them.

Wow... Very nice buddy. Seems like you could have an awesome combo there with just a little more tweaking!

Dang that 300 shoots. Hope to see you hammer a big bull with them.

Thank you for running that for me, Dr. Mike!

Scotty, I think I'm going to try .110" and .120" jump with the same charge and see if that tightens it up. After that, I'll use the depth that shoots the best and start bumping up the powder charge. I think I can tighten it up a little bit more. Hopefully I can punch one of these through a bulls shoulder this year.

Your load at 74.5 grains isn't exactly loafing along--its pushing between 2760 and 2800 fps, which isn't bad. That is a tremendous amount of energy delivered on target. With that measure of accuracy, you're definitely ready to tackle the big boys. If you can get more accuracy with higher velocities, of course you should do so. However, I wouldn't be terribly distressed to use what you have if push came to shove.

I agree completely. The fifth shot very well could of been me, I was getting pretty excited after the first three clustered so well. If like to get 2,900fps with it. I've easily gotten that with 210 and 215 Berger's, but I also have to seat the ABLR's MUCH deeper into the case than I did the Berger's, so my usable case capacity is severely reduced. I have no room to complain about how they shot today. Velocity and accuracy are more than enough for hunting.
