Altitude has no appreciable effect on muzzle velocity. It has a ton to do with down range performance as there is less air density/drag enroute.

SuperJlarge below brought up the most important variable here that is not addressed. MOST powders require settling in with 8 to 10 shots after being shot through a barrel with a different powder previously. David Tubb talks a lot about it, and it would be pretty rare in competition to change powders without being able to "foul" the barrel with the powder you intend to perform with. I've gone from W748 to Reloader 15 and had shots so wildly out of the target zone they were laughable. After about 5 shots...the barrel settles right back into the Reloader 15. That goes the same for trying it the opposite way. All that said, there is no sane way to do all that in a test like this that is awesome to watch!

Put your best groups into Gordons reloading tool and they seem to all be right at a optimal barrel time node. Based on this, if you want a couple other powders to try for high velocity, try 23.8 grains 8208 xbr and 23.6 grains of H4895. H4895 is predicting some crazy numbers, so be careful and don't blow your face off. it is possible you might have to fine tune the charge a bit as I do not have all of your exact numbers for bullet length and case capacity, but it should be close.

Johnny, great series, It's a treat because I'm enjoying reminiscing. I hate to talk about or waste time in doing it, however, back in the day (The early 2000s) the AR was the rifle to use to keep people in the shooting game without breaking the bank, LC 5.56 once fired brass could be had for a song, .22 Projectiles were cheap, an 8 lb jug of pull-down IMR-4895 was all you needed to compete as everyone was at the same level, Shooting .30 got to be a financial unfeasible thing to keep up with and less and less M-1's and M-1As were on the firing line and as with all things, the page turns, many powders you shot today were all being used to get the competitive edge back then, I see that AR comp has been a product that has risen from those times (Accuracy and higher velocity). I believe that the Good people at Hornady remember those days also and offer a line of bullets that keep people on the Firing line, competing, practicing, and winning and that's what it is all about. Btw(I like the fact that you shoot with the chickens) Peace out dude. Dave

I've tried at least a half dozen powders, different seating depths, different cases, case prep...none are really any good. Once in a while I'll get a ~1" group, but nothing to get excited about. Meanwhile, it shoots Hornady's 68 gr. BTHP over 25 grains of Varget into .75 to 1" every time. I've hit 4" swingers at 500 yards with it 8 out of 10 times. And at 2835 fps, it's ballistically the same at distance (or better) than what I've been able to get out of the heavier bullets. I love experimenting with it, but that gun is really happy with that load. Load development can be weird and frustrating, but it sure is fun.

Johnny, your work is greatly appreciated. I love this stuff. If I could make a request though, I would love to see a test of the Berger 70 gr VLD loaded as a long range AR round. I know the 77 gr SMK can do well at the longer ranges out of an AR platform, but there is some data - I'll let you research and determine what to use - that suggests the 70 gr VLD can be pushed to over 3000 fps MV, - around 200 fps faster than the 77's which give it a very nice head start, and the BC of the 70 VLD is pretty good at .374 (G1) so it should outperform the 69 gr bullets for sure. It may have to be loaded to 5.56/Wylde pressures to achieve this, but I'd like to know. This bullet would also stabilize better from slower twist barrels allowing it to be used in barrels that can't stabilize the 77's.
