When it first came out, some of Hornady's 105 factory loads were loaded too long, and jammed the lands especially when combined with some short throats.  Result was way over pressure.
Add in that the AR is not a precision chamber, and that some bullets could slip forward during the slam-feeding of the bcg, all together just doesn't seem like the path to choose.
If we were talking about a bolt action precision rifle and chamber, maybe things would be different.  Maybe OP and Kmw's pipes are bolt action, It's close to midnite and I don't remember (this John Wayne movie is about over too, lol), but anyway... in my book 20 off is about as close as I want it to go.  Remember these are mid-pressure cartridges, not 58-60 etc etc ksi.  I even have to keep reminding myself of this, anyway.
Anyway, I want my Arc loads to have some jump.
I think that is what this guy Eric C says but instead of Lands he talks jam and then backing off .20 to start then work backwards from there. I know when I tried that OAL tool  with the cartridge screwed to it I cannot get the same results twice. But putting a cartridge together then chambering it to jam it in , I come out with a lot closer measurement  and have that cartridge sitting on my bench to compare to. 
Anyway, waiting on my rifle to get back then am set up to try LR vs 2520 and the new barrel tuner. Looking forward to it.


On another note . I'm in to bad of shape to walk public land been going up to Alabama and hunting with some schools up there that do fund drives for their school .  But found a spot in South Carolina to go this year . Anyone been hunting in SC ?

So 2 trips to Alabama and 1 to SC this year to try it out

Thanks for the input , this site is always up for some good opinions.
