Marty,
this is a 10 shot 100 yd group I fired on Sunday with the Remington M700 I had Derek convert to fire .458 SOCOM.
The load was a Remington bulk 300 gr. JHP, 31.0 gr Alliant 2400 powder, CCI350 primers, and Starline brass. If all goes well, my new thunderstick should be just the ticket for Whitetails come November.
I know its not an AR15, but it is a .458 SOCOM.
Just thought I would share.

I'll print this out and show it to Derek this afternoon. After watching him build your rifle I became green with envy. I'm still looking for an appropriate 700 to do the same thing to.

Need pics of the rifle, considering this build.............

Very nice group !

10 rounds and you still didn't hit that quarter glued to the target

Nice shooting. Try Reloder7 I think you will like it. Along with your "standard" M700 we did a ETRONIX M700 ... not even the sound of the sear and pin to make for an ultra quiet package ...

I have tried Reloder7, H110, 296, 2400, and LilGun. 2400 gave the best groups so far. I recently discovered some contact between the barrel, and stock, that could be causing flyers. Once I relieve the stock, I may re-shoot the other powders, to see if the flyer problem cleared up. By the way Marty, do you notice a lot of unburned powder granules in the barrel after shooting with Reloder7? I would think that not having a consistant burning of the powder, would be bad for accuracy. I use CCI350 primers in all of my .458 loads, if that matters.
I hope to have pics of the M700 posted here in a few days.

I also use the CCI350 primes and RL7, and notice a fair amount of residual, unburnt powder after shooting.

Re7 was giving the most consistent results with the 500 gr subsonics and hadn't noticed residual, however, my starting temp these days is 105F

Norma 200 was working really well but started to become difficult to find .... just surprised that A2400 is giving the best results .....

Here is a pic of the rifle that shot the previously posted target.
It started out as a Remington M700 Varmint Special, chambered in .308 Win.
The stock is a Bell & Carlson composite, with a rattlecan ( spraypaint ) camo job.
The barrel is a Pac-Nor blank, cut to 18", and profiled to match the factory Remington varmint contour.
The barreled action is Parkerized.
The scope is a Leupold FX-2 6 power, 36mm objective.
Base is a Leupold Mark4 1 piece.
Rings are Leupold Mark4 medium height, 1"dia.
Weight of the rifle as shown is 8.5 lb +/-. ( I weighed it on a bathroom scale )

Yeah, I think he needs to adjust the elevation a little too.
I always liked when my groups cut out the X from the middle of the target, aiming point be damned...
