![]() ![]() I've been loading for another buddy who's using 80 grain Sierra BTHP MK bullets and I used the ADI specs of 2.55" COL as my guide and they shoot spectacularly well over 300 yards. 223 and has some input on seating depth/COL. I'm just hoping somebody has had some experience with these 69-grain bullets in. 223 for years and I just load them to 2.26" and they shoot brilliantly. I set the Cartridge Overall Length at 2.258", then went to the ADI load data for powder charges and found to my surprise that ADI lists the COL for this bullet at 2.235" - which is 25 thou SHORTER than what they list for the 60 grain V-Max bullet that I'm using for 300-yard matches.When I looked at how deep into the case the 2.235" seating depth put the bullet, it was down past the base of the shoulder! Minimum powder charge with AR2206H is 24 grains and when I loaded to ADI's specifications, I felt the powder crunching already! Maximum charge is listed as 26 grains a compressed load, but I'm already compressing the powder at 24 grains! I've been using 55-grain bullets in my. 223 cartridges for a friend of mine and the first thing I did was put together a 'dummy case' to make setting up the seating die easier in future. I've just started reloading 69 grain Sierra BTHP Match King bullets in. ![]()
