Home Forums Hunting & Shooting Custom Rifles & Wildcats First round of test's with 75gr A-max and the .220 AI

I don't know how many are actually interested in this but I have had a couple ask in older threads and a few PM's for updates so I decided to just post it.

I am trying this 200 yard load develpement for the first time

http://w w w .longrangehunting.com/articles/reloading-load-tuning-1.php

It is working out great and looks like I might have a load in under 60 rounds tuned for great long range accuracy. If your board it's worth a read. The author is also the guy who put my rifle together.

Got out with the .220 AI today. It was a chilly morning with 8-10mph winds. I have never really done precision load development before. I am a 100yards try a few loads and take the one under an inch with a hunting bullet kind of guy. Never payed attention to vertical or other little things.

Two things to consider. The wind, and Iam not the greatest shot to begin with. I loaded 40.5gr-44gr of reloader-22 in .5gr loads. 10 thou off the lands with CCI BR primers. Shot at 200yd and the squares are 1 inch in size. Used a front rest and rear bag off a bench.

Every barrel usually has 2-3 accuracy nodes. I believe I found both, one with the light charge and one around 43.5 the reason for just two shots is your just looking for oriantaion of the group and how tight. I will now go back and load two sets of 3 round groups of 43.5/43.7/44/44.3/44.5 and shoot them again at 200 to see if I can get similar results with 3 shot groups x2.








Thanks

That is pretty impressive. Nothing to sneeze at for 200 yards. What scope are you packing on that rifle? How much more speed can you gain with a 220 AI over the 220 Swift?

I've found RL-17 to be a good powder in that case.

The 80 A-Max and 90gr. Bergers have shot better for me, but not much.

Thanks for sharing!
