I gotta hand it to the folks in Yonkers. (Now, Dennis and Winslow, read this...)
I stopped by my favorite gun shop this evening and saw a Kimber 1911 Rimfire Target .22ACP Government Model in the case, and immediately had to check it out. What a beauty...tactical black... slide and frame made of light machined aluminum alloy with classic black-T type coating....fully adjustable Bo-Mars...HAD to HAVE IT.
Plunked down my $599.95 and brought it home.
So, after a quick strip-down and COMPLETE lubing of the weapon with FP-10, I took 3 types of .22 rimfire to test (and just shoot the heck out of it). I dragged out my bullet traps in the warehouse and commenced a shootin'.
The 3 types were:
1. Remington .22LR brass coated rounds (bulk stuff but highly accurate and effective in my Kimber Classic, P-22, Ruger, etc.)
2. Remington Sub-Sonic
3. Aquila SSS (Sniper SubSonic, 68gr bullets).
How did they and the Kimber fair?
Well, the consistent and constant cycler, with no alibies, was suprisingly, the Aquila SSS rounds. These are made for bolt action rifles, but performed flawlessly in feeding and extraction. Went through a whole box of these. The only interesting thing was that they shot fairly accurately, but every hole was oblong, which indicated that the bullet was not being stablized well enough by the short, 5 in. barrel. This is no fault of the pistol, as I said, they were designed for longer bolt action rifle bores with an optimized twist for higher stability of a heavier bullet. But, reliable?...as all-get-ot in feeding and extracting.
Next, the Remington subsonics were a bomb. None of them would cause the pistol to "full stroke", causing me to manually eject each round. The bullet-mass of the Aquila SSS (68gr) was much larger than the subsonic Remington (52gr, I think) and compensated the energy needed for blow-back operation.
Finally, the good old Remington standard, .22LR, was intermittent at best. The cases ejected fine, but more rounds would NOT fully seat in the chamber which prevented it from going into full battery, than those that did. I ended up having to give a little "thumb push" on the rear of the slide, almost every shot.
Now, I disassembled and cleaned the barrel, chamber, and receiver, between each type of ammo, so there was no build-up of burnt propellant or debris to be found. (Talk about EASY to take-down, with no thumb-bustin on the bushing or anything...just plain IDEAL) The slide to frame fit is perfect and feels like glass on the cycle. The magazine is one of the finest constructed polymer mags I've ever seen, with ample spring-to-follower tension.
So, my thoughts lie in two areas.
1. Is the recoil spring sufficient (as it seems fairly light to me, but thats just an imperical observation)?
2. Is the brass-coating of the Remington LR rounds creating enough friction at the vertical hood of the chamber (as opposed to the plain lead) as to cause the slowing of the round when being fed into the chamber to stop just about 1/16th of an inch from full battery?
I'll pick up some Federal, Winchester, and PMC stuff tomorrow and give that a go.
But, in reality, a properly ramped, champhered, and fit barrel, should eat anything of a round and tapered bullet design, as long as the spring tolerences are sufficient to release enough energy back to the slide for full battery effect.
I LOVE this Gun, and it is just plain sweet, gorgeous, and accutate as hell. Need to get it feeding properly and then, perfection will be attained.
I'll post back on the other ammo tomorrow night.
Best regards,
George
