Can anyone report on the velocities they are obtaining using the 69 grain Lapua out of a 20" barrel in .223 on an AR platform?
Thanks,
Jordan

Ive gotten good accuracy from the 69 SMK's with velocities around 2800-2850. I would assume the Lapua's could go the same speed.
I am sure they could be pushed faster but I am not one to chase pressure signs.

2950 is about tops for a smk. Never fired a lapua in my life. Sorry.
2950 is also very warm and has to get there with some fancy doings to be safe.

I'm getting 2950-2970 fps with 69 Sierra MK's from a 24" barrel. Haven't checked them in my 20", but I'd expect 2825-2850 fps, and they shoot very well at that velocity as well.

I am sure they could be pushed faster but I am not one to chase pressure signs. I'm running the 75gr Hornady BTHP out of my LTR at 2760 (avg), which is pretty in line with what Hornady lists for a 20" service rifle. I'd assume that with the slightly lighter bullet and appropriate powders, you'd be able to bump the velocity up into the range suggested by Wareagle.... Kaiser Norton
