I wouldnt stock up until I had a chance to try several variations to see what the gun likes
However for general plinking and informal target work I have had good luck with Federal Auto Match in most guns and its relativley cheap

 

Yep. Going to use the box I have for the IV's first shots and see how it runs.
Thanks.

 

Personally, I don't think anyone can ever go wrong with CCI Mini Mags to break in a gun and /or feed it going forward ( for general shooting. not so much match/ bulls eye). These rounds famed for their consistency and their willingness to run in anything. If you shop right, they can be had for under 7 cents/round in case lots.
That said, while Mini Mags are my "go to" for reliably running any semi auto, I've also have very good luck with Federal Auto Match (at 5 cents/round).

 

I've also have very good luck with Federal Auto Match (at 5 cents/round).

Just ordered some at <.04/round shipped(5 box min). Figured why not.

 

I've tried the following ammo and gr. sizes in my MK IV. Bullet weight between 36 gr & 40 gr were tested.

For accuracy and overall number of FTE per 100 rounds in the MK IV, my M&P 15-22 and my old Nylon 66; the CCI MiniMag 40 gr came out on top, followed closely by:

Federal Value Pak 325 36gr

Federal American Eagle 400 pack 38gr

Federal Premium HV Match Gold Medal 40gr

The Federal AutoMatch 40gr had a few more FTE issues with my 15-22 & MK IV but the accuracy was good.

Best accuracy in the MK IV was a toss up between the CCI MiniMag and the Federal American Eagle.

 

I've shot just about everything in my MK IV, 22/45 Target and the Mini-Mag 40 grain SP, shot tighter groups than anything else, including the Eley Target. I'm getting literally one-hole, 25 yard groups with it.

 

I would also recommend the 36 to 40g CCI Mini Mag. I often buy the 40g round nose when they are on sale. Standard velocity shoot well also. I always have a bulk pack of Remington Golden Bullets around. I let the kids shoot those up. I’ve not had many complaints about the Remingtons.

 

Can't go wrong with Mini Mags. I've also had good luck with CCI Blazer lead round nose bulk pack ammo.

 

I have a MK IV 22/45 Target I have had a couple months now and it has functioned 100% with any ammo I have put through it. Blazer, Rem Golden, Federal 36 gr HP bulk pack and some CCI std velocity. Your MK IV should run 100% with anything you feed it too.

 

Have run just about everything in mine but mainly CCI Blazer, because it's cheep. We shoot a monthly match We call i tac.22, it's shot similar to cowboy action but with semi auto .22s, and we really burn up the ammo so I purchase the cheep stuff and the only thing that has given me problems is Remington Thunderbolts.

 

when I got my IV target the wife gave me a box of golden bullets i burned thru those without an issue but went back to CCI Mini Mags. at my range we shoot bowling pins once a week and everyone that comes for that seems to shoot the mini mags as well. I have only had a couple of stove pipes. they run pretty smoothly which keeps the gun happy.

 

Have a bucket of Rem Golden Bullets. Eager to try with the new MK IV which just arrived at my LGS. Picking up tomorrow.

 

I never had any luck with any of the Remington bulk .22's (ever and in anything.) Hopefully your results differ as I recall a "bucket" was a couple of bricks worth.

 

Mini Mags or Browning Performance Rimfire.

 

Minimags are consistent, accurate, and available everywhere. When I can get them at a bargain, I like federal automatch and I have found Aquila super extra copper washed (not leaded variety), when available to be very accurate and fairly clean burning Cabelas usually has it at a fair price.

 

Now that the Supreme Court is secured conservative for the rest of my life - and probably my kids’ lives as well - I’m no longer buying whatever I can whenever I see it. Almost all my .22s like CCI mini mags. Thus I’m burning up my stockpiles of non-CCI and replacing with CCI as I go along.

In terms of value, I do have to give a big recommendation for Aguilla stuff. Their high velocity LRN stuff goes for about $2.45 / 50 rounds and is pretty accurate and consistent in my guns. You will find an occasional defect, say one out of 150 or 200 rounds might be bent or flattened, but still hard to beat for the money.

 

after trying many different kinds of ammo, my MK IV is most accurate with the Federal Auto Match the best, followed by the Remington Bucket'o'bullets coming in a surprising 2nd. These shot better than all the CCI's and other more expensive ammo. YMMV.

 

Thanks. Picking up the MK IV today.

 

The only stuff I shoot through my MKII, MKIII, and S&W 41 is Federal Auto Match; clean, consistent, accurate, and reasonably priced.

 

In my experience, can't go wrong with CCI.

 

JL,

In my MKIV 22\45 Lite experience (overall range report HERE), keeping with the CCI Mini-Mags HV CPRN, or even the CCI SV LRN, will probably continue to be a good idea for the newest 22\45 Target!

As has been said, individual .22's may really like a particular ammo, or hate it. There's been some good suggestions in this thread...just have to give them a try and see for yourself with Your pistol!!

I start with CCI Mini-Mags to set a benchmark for comparison, they feed in everything and aren't awful for accuracy. Then go through Federal Auto-Match AM-22, Federal HV Match 719, Federal Target 711B, CCI Standard Velocity, and if I'm really feeling good about my shooting, something like Eley Club or Eley Target. I shoot my Mark II off a rest to test for group size, to eliminate most of my hand movement.

 

CCI mini mags for first 200 rounds minimum. I personally would do more than 200. Once broke in go for gusto and try whatever.

 

Across the board in my .22's I've found that CCI Standard Velocity is most accurate at 50 yds and under. It is nearly as accurate as many of the more expensive match ammo (I've had the most consistent accuracy with Wolf Match Target). I'll use MiniMags if I want a little more terminal performance.

 

Can I ask where you found them for .04 a round?

Bought a new Mk IV Target model back in the summer. Mine has run fine on CCI Blazers, CCI SV, Fed AM and Aquila SV.
