I worked up some loads for a 250gr Hornady A-Tips. RL-33 was slow and disappointing. Retumbo showed promise. Vihtavoruori N565 shocked me. Seated to marry boat tail to neck/shoulder junction. 250gr A-Tips seated at this point are too long to work in AI CIP mags that are 3.850. Started at 76.0 grains, next was 77.0 grains...78.0 grains....79 grains and 80grains at the end. I did not think I could shoot the 79 grains...much less the 80 grain load....but I showed no pressure at 79 grains...IN MY GUN....and 80 grains showed slight ejector swipe.

I've been pushing an accuracy load of 225 ELD-M's at around 2931 with an SD of 4.0 that showed to be stupid accurate (10 out of 10) at 1000 yards this past Sunday. Stupid accurate at 1760yds (1mile) 3 out of 5....and the misses were my wind calls...vertical was dead on.
Here is the data on the above test loads for Vitavoruori N565....it may show to be awesome at 1 mile...or it could show that the 250gr A-Tips may be not worth the extra cost over the 225 ELD-M's. The 230's have proven to be very good to a mile as well...and a few weeks ago hit 2500yds.
But... 250gr A-Tip and N565:

At the end of the day...I had fun...and that is all that counts
