Re: New 6.5 Grendel Build Complete. (PIC HEAVY)
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: AlcoholicusRex</div><div class="ubbcode-body">Nice Build. I have a heavily modified AA Hunter model that bears striking resemblance to longrange 30's rifle. I have been doing load development for a long time on this rifle. I did find a very accurate load at top safe pressure and velocity, using 30.5gr W748 & 123gr Scenars.
The new batch of W748 I bought was not as dense as the old lot, and I started deforming the 123gr Scenars in an attempt to duplicate the previously attained velocity. I started from zero doing load development again, and the only powder that gets me there (2500fps) safely is XBR8208. I am currently shooting a .4gr over max load using Xterminator, which has given me the accuracy and velocity I want, but has drawn severe, sarcastic, and even morbid criticism from senior members at the Grendel forum. Please don't use this load unless you want to end up hideously disfigured or dead.
My Grendel experience has been up and down. There are issues with any magazines that are not sold by AA. Make sure you buy the bolt and barrel as a set. Ammo and brass have been EXTREMELY hard to procure until recently. The muzzle threading on AA barrels is an oddball size, limiting your choices on muzzle devices. I had mine threaded to 5/8x24tpi, and using a PRI QC brake can spot my own rounds out to 750yds so far.
If I had it to do over again, I would get the 24" barrel with a carbon fiber ff handguard, this would give me more powder options.
I'm not by any means an authority on these rifles, but I have been tuning my rifle and ammo and magazines extensively, and need to offload some of the shit I've learned
I would like to post a picture, but am too obtuse to figure it out. Help Me? </div></div>
For mags I mostly use the C-products 10rd mags, they work the best for me and I never had a misfeed with them. As far as the muzzle threads, yes it is a wierd size but there is a wide range of muzzle brakes/flash hiders for it you just have to look around for them.
I also get great results with the 123gr. Lapua Scenars and win748 (as seen in my pics at the top)
Im glad I picked the 6.5 Grendel over a 6.8SPC or .308 AR platform, IMO I think the Grendel is more accurate than the both of those. My next AR-platform build is going to be a .260. I cant wait to start that build!
The easiest way to post a picture is: Go to Photobucket.com and make a Album and them right click copy the IMG code then paste on your new post-DONE. Its easy. im sure there is other ways to do it but thats the best/easiest way I found to post em'.
