For Varminting out of an AR, the 6mmAR (a 6.5 Grendel necked down to 6mm) is a great varminting cartridge. I recently did some chronograph work shooting the 6mm Hornday 75 gr VMax bullets out of a 24" barreled AR-15 chambered in 6mmAR. The results are as follows:

29 gr H4895, BR-4 Primer, Horn 75 gr. VMax 2943 Mean Velocity, ES 25, SD 10
29.5 gr H4895, BR-4 Primer, Horn 75 gr. VMax 3014 Mean Velocity, ES 17, SD 8

Attached is a target with a 10 shot group with the Hornady 75 gr. VMax bullets, shot prone with a sling (no rifle support so body movement and pulse is included in the group size). These things will shoot bug holes from a rest. Little recoil and lots of fun.

Well, it sure would be fun to put one of these together but my local FFL won't work with me on this because of California assault weapons laws. In fact, he says that anyone in CA who has a pistol grip, semi-automatic with a detachable magazine is breaking the law and subject to arrest on felony charges.

Does anyone living in CA have any input on this?
Thanks, shcal.

ShCal,

Yes, unless you owned an AR15 prior to the CA state ban, and registered it as an "assault weapon", you can't buy one or import it. You can purchase a pump-action AR, or one which has had the magazine well permanently blocked. With the latter you have to raise the upper and load with stripper clips, or single load. Given those restrictions, a bolt action is probably a better option.

With the current state of the CA legislature (Democrats controlling both houses), it's unlikely you'll be able to buy an AR-style rifle with detachable magazines any time soon.

Thanks Moderator, that pretty much puts an end to my AR varmint dreams. Oh well, back to the bolt-gun drawer.

Can he purchase a used pre-ban or post-ban gun?

I don't know how many bans they've had but I bought the "post-ban" lower that was legal without the bayonet 5 years ago or so. I quess it doesn't really matter since I live in AZ now. I wonder if I can bring it back to cali when I head out there for bid'nes trips?

There are some great things about California, I'm trying to remember what they were now.... Oh, yeah it's not 120 deg. in the Summer, that's about it

No he can't buy a used AR15, registered or not.

AR15s all must be registered, or possession is illegal in California.

Once they are registered they are non-transferable to anyone in state--you can't even sell them to a California-based FFL for consignment (and future out of state sale). A registered AR, can, however, be sold by you personally to an out-of-state buyer (provided you ship to out-of-state FFL and comply with all local laws.)

And you can't even pass them down to your kids.

When I was shooting so many p. dogs, I had a custom AR built by Bill Wylde, his work is superb. I had a Heavy Hart 28" in length installed on a Colt action with a custom set trigger. I could agg five 5 shot groups in the .285 area in a 9 Twist. I had a heavy flat plate attached to the bottom of the forearm like Larry has on his.

When shooting p. dogs, I found that I simply wiped out the p. dogs in the areas that I was hunting in. I had 18 thirty round mags and 20 of the 20 round mags with the 20 rounder being my favorite.

If I remember right, my rifle weighed 15 1/2 lbs with the heavy bbl, bird shot in the butt, and flat plate on the forearm...simply a joy to shoot.

I got rid of it because it was not fair for my hunting partner. When we would roll up on a dog town, the p. dogs seemed to be feeding in groups. I would start off on the edge of the "party" of dogs and work my way to the other side, killing most of them. If there was one sitting on the hole, I would plug the hole with several dogs, then the rest would just run around. I was shooting a round off every 6-8 seconds when working on a "party" of dogs. It really unnerved my hunting partner with the constant bang, bang, bang, bang. Also, I killed most of the dogs in large concentrations. Many times he would complain that he had a dog in the cross hairs taking the slack out of the trigger when my round would knock over his target.

I sold the AR when the prices went sky high, and my hunting partner was tickled to death!

Needless to say, shooting the AR on a p. dog town reminded me of the use of the Sharps rifle on a Buffalo herd...you just kill them all.

One of the negative aspects of using an AR is that many of the farmers and ranchers that allow you to hunt are not accustomed to seeing assault rifles used on game. They really get a little rattled at the excessive firepower that was being used on p. dogs. I have had many ranchers ride out and check us out due to all of the incredible number of shots that I was firing.

Also, it seems that Game Wardens and Deputy's are un-nerved by the use of assault rifles on game. They really checked us over closely when hunting coyotes when I was hunting coyotes with a Colt Government Model AR-15. This is probably due to the fact that they know that they are out gunned.

I am building up a 6mmAR Varmint rifle upper for a customer and I have been doing some chrono testing with one of my 24" barreled uppers to see what it will do with the bullet the customer is expecting to use (the 6mm Hornady 75 gr. V-Max bullet).

Today's chrono results (with a different lot of H4895 than previosly posted on this thread) were as follows:

29 gr H4895 w/ Horn 75 gr VMax - 2986 fps
29.5 gr. H4895 w/ Horn 75 gr VMax - 3046 fps
30 gr H4895 w/ Horn 75 gr VMax - 3099 fps

The 30 gr load did not pressure out and now I am wondering if it can go 3150 to 3200 fps with it.

The extreme spread with H4895 was a bit more than I like to see (around 30 fps) and I suspect by trying other powders that can be brought down, but 3100 is definitely a workable velocity with the 6mmAR.

To give you a better perspective of the cartridge, attached is a picture with a 223 (on the left) with a 6mmAR (center) and a 6mm 75 gr. Hornady VMax bullet (right).
