Thread: Load determination / Handloading for my AR15

I have not as yet determined the seating depth, as I dont have the hornady tool but the club does I think so I might pop up there at some stage and use it to see if I can set a longer OAL.

My first loads are just to see that the gun will cycle OK so I have started at 22.1gr 2208 and gone up to 23.6gr in 0.5grs for each projectile, anyone have a comment on these loads? as I cant find an accurate min loading for a 62gr FMJ I am usng a close SP. I have emailed ADI about that hopefully I will get a reply.

As an aside 2208 / Varget doesnt meter well? so is there a better powder choice for a progressive press?

Does a variance of 0.2gr matter on a 223? I assume not to say 300yds?

Having only shot 30cal to 1000yds 0.2gr matters not. But 0.2gr of 45 grain v 0.2gr on 23 grain is x2 the % difference and the projectile its acting on is x3.

Steven I would say that 0.2gr should affect groups vertically as it is quite a percentage difference in a small case.

I find that 2206h meters well through my Lee powder thrower. Haven't used 2208 before to compare though.
