Today I went to the range to test my Kimber .22 conversion kit on my Ultra CDP II frame. I also needed to test my Walther after some hammer alterations but I'll leave that for the rimfire channels. I don't see a rimfire specific category so I hope it's alright to post it here with the big boy guns.
I knew from you guys and other sources that I needed to run high velocity ammo. Fortunately that's all I ever shoot. I tested the gun with the array I usually shoot. Here's the ammo:
1. Aguila supermaximum; hyper velocity, 30 grain, 1750 fps. These are supposedly the fastest .22 rimfire made. Always enough blowback to cycle all of my automatics. It has a very strong peculiar power smell when shot. Usually very reliable
2. CCI Stinger; hyper velocity, 32 grain, 1640 fps. My favorite ammo. Always cycles all my automatics. I saw a youtube video that showed it only measured 1190 fps out of a 4" barrel but that's still hummin. The case is longer and isn't made to shoot in a match grade rifle chamber.
3. CCI mini-mag; high velocity,40 grain,1235 fps. My go-to ammo for reliability in pistol cycling and always fire. CCI is about the cleanest ammo I have found in .22. (as if clean is really clean in 22 ammo) For plinking I do like the 36 grain mini-mags better.
4. Winchester M22. A bulk ammo that I had bought 6000 rounds of before the scarcity. I'm telling ya...this is every bit a CCI mini-mag clone. It has a black coated bullet but the power and reliability has been right in line with CCI mms for me. No duds that I have found, cycles every gun I got. Some say it's a tab bit dirtier but I haven't noticed that.
5. Armscore; high velocity, 36 grain, 1260 fps. It has the bullet shape similar to Remington golden bullets which I never liked much. They are copper plated(washed), have good velocity to cycle but are very dirty. They also are a little waxy for my liking and duds are common like in the other bulk ammo.
Now for the gun:
I decided to start at 7 yards using my favorite, CCI stingers. I use them sparingly because the 3500 rounds I bought a few years ago @ 10 cents a round are now selling @37 cents+ when you can find them. The target is a little misleading because although it is a silhouette it is much smaller. The orange stick-on dots on the last target picture are the size of a penny. After a few fast reloads I brought it in for a picture. The gun functioned flawlessly.
Next I took it to 15 yards to see if I could get some headshots. I used CCI mini-mags. I hit the head with a few fliers. I know the purpose of this conversion is to practice with .22s with sights like on the 45 slide but for precise shooting I wish they were a little thinner. I spared no ammo in this test with no malfunctions at all.
Next ammo was the Winchester M22. Lovely...smooth as silk. brought the target in to 30 ft for some rapid fire. I love the feel of this gun.
Started to run out of places to shoot at where I could tell where I was hitting so I stuck my ole stick-on dots on the target and switched to the Aguila. Lots of power and plenty of muzzle flash to put on a good show for the big boys. Pretty loud too. What a peculiar smell though. Ran great.
Last ammo was the Armscor. I had bought this the most recently when I thought I better buy something instead of shooting up my favorites. The velocity is great. Cycling no problem and chambering never failed. Halfway through the first 50 rounds I had a dud. Re-cocked and the second strike fired it. One other round did that but it was in my Walther P22.
So I ran through lots of ammo and no malfunctions of the gun at all. I am REALLY impressed. I say that because my Walther needed a little custom fine tuning with the hammer to cycle at 100% which it did today. Guys, I highly recommend this conversion. I'm all smiles.
My 2 finger was asleep...the correct range date is 2-25-16
