6x45 heavy cast experiences?

[jiandawg]

I was considering building an ar15 in 6x45 and was curious if anyone had any experience with the NOE 246-105 in this caliber in an AR platform. From a lot of what I'm seeing most people are running in the sub 80gr and sub 2400fps range with success, but I wanted to maximize the muzzle energy by increasing weight. From what I'm seeing on some load data, the hornady 100grs can be run at 2300-2400fps with decent pressures.

Thanks.

I assume you meant to use NOE 243-105. I show a Lyman 99 gr cast boolit can go 2286 fps safely at 45353 psi in a 16.5 in barrel. Energy is at 1164 ft lbs with 19.5 grns of IMR 4198.
