I just chronagraphed my 44.5 of Re15 -155 Scenar and had a average of 2750fps shooting a Gap semi auto 24inch Bartlein barrel. 30 degrees temp. Does great groups. Will this speed get me to 900 yards or should I look for a higher speed. Thanks, Lance

Re: Gap ar10 155scenars/Re15
Lapua lists BC as .508 I use .504 and launch them at 2950 fps. You can push your velocity up a lot from where you are. I've shot my load out of an ar10 before.
I would imagine it would make it, but this should give you your answer

900 shouldn't be a problem, even at 2750. Are there any pressure signs with your load as is?

Don't know if this helps at all, but I have nailed the gong at 900 on the first shot a couple times with my AR10 shooting 155scenars in Win brass and 45gr IMR4895 at 2743 fps. Does about .5 MOA at 100 all day long.

Re: Gap ar10 155scenars/Re15
Looks like you're getting some good results with RL15. I went with Varget for my AR10 needs and I may have gotten the slowest lot ever. I'm getting the same velocity but with 46gr. 46.5 and I start getting swipes and the SD goes haywire. I was hoping to at least break into the 2800-2850 range with the 155gr SCENAR.
Barrel is a 21" Stainless Noveske with 1/10" Polygonal Rifling.

Re: Gap ar10 155scenars/Re15
I'm starting to work up loads for my AR as well. Just bought an Armalite 10t with the 24inch barrel. Rifle is stock as far as I can tell. It seems to like 175's.
I apologize for stepping in on your thread but I would like to ask what mods should I try first on my AR. I'm wanting to shoot to 900 with this rifle and stay within an MOA. Looks like the 155's are a good start. What else should I be looking at?

At just a tad over 2800fps, RL15/155scenar, was 26.5moa to 900 with 200yd zero a couple weekends ago, 50 degrees.....32.5 at 1k.
