I just shot my new 6mm arc ar today. I finished slapping it together last night. I only shot to 550 before the wind went nuts, but was getting groups just above .5 about .9 all morning with factory Hornady ammo. I couldn't imagine buying or assembling a long range varmint/predator ar in anything else.I haven’t either although I shot a couple in Wyoming but never over P-dog town. That is something I have to do. I need to get a AR rifle in 223 I hear that the are capable of some real good shots !
Me too.... mine a Unitah Precision Bolt Action and it shoots almost .5 out of the box!! Actually,one 3 shot group was .625ish and rest were more like .720-.785zzzz but oh baby is it a cool round. I'm about to pee my pants having to wait to hand load for her til next week,hopefully those .785 turn into .485 or close to it...... Bahahahaha. That would make 2020/Covid year, "to me" just alit'l bits better. and 2021 looking really a lots better..........now comes a new drop in barrel and upper for semi........ I Love The USA (Special Thanx to my 3 Kids) and all the Service men and women//// First Responders Best wishes to all going into 2021 and Beyond....... Shoot Small///Miss Small Thanks Len for a place we all can enjoy and call home,while sitting at home safe,warm,loved and free to do so to a 100yards or 1000yards.

Sounds like a Leupold commercial. "All you have to do is range it, dial it, and shoot it."As many know I had posted about some incredible shooting that I read about on a different forum. With some motivation from members I question the poster about his developed technique . The questions I ask were , why are you using 40 and 50 gr vmax bullets when the trend is for longer heavier bullets with better coefficients ? What scope are you using and how are you setting it up . How are you zeroing your rifle reminding him his set up in a 30 mph crosswind at 850 yards had 34’ of drift and 23’ of drop. 1 mph variation of wind could change drift 15 “ at that range. Here is the response .I will paraphrase.
Pmacc you are exactly right using small varmint bullets for long range that’s not the normal way to go. This was a research experiment just to see what the effect of sonic transition had on these smaller bullets.The scope was Vortex EBR1 reticle with 30 mos adjustment mounted on 20 moa rail . He said he needed all of it .He said I was right about the wind being a big factor , 1 mph or 5 degrees it could become difficult to predict hits. Next the strategy !
This shooter stated that from the muzzle to impact (850 yards 40 or 50 gr 223 cal ) it took aprox 2.5 seconds for the to impact.using a AR -15 24 inch barrel . Using the semi auto advantage he would fire a shot waiting to see impact and in 1 second, fire a second shot then third if need making slight adjustments on each shot as needed. Forth shot was rarely needed .The wind held steady at thirty mph for about 10 seconds .
His observations , impact predictability was much better than ever expected ! Once range and wind were dialed in hold overs were very consistent .
2 There were no ricochets , no scaring of the p-dog population. Bullets burying in the dirt.
3 The low subsonic <800 FPS bullets hitting rarely noticed by the p-dogs most Lilly because of no supersonic crack .
4 P-dogs did not blow up on impact they fell to the side because of big angle entry due to the wind!
Closing his thoughts were longer heavier bullets may lead to ricochets that could be up to a mile with VLD bullets
His most deadly cartridge is 6 mm Creedmoor using it to 1400 yards .
I had to paraphrase but I tried to give this shooter accurate representation . If you are coming in on this post only go to the post Har to believe .
