I plunk tested Xtreme 115 grain heavy plate concave base bullets. They worked all the way to 1.165 OAL. I use Bullseye powder and get best accuracy with longer OALs and generally set mine at 1.150. Haven't had any problems running them in the R51.
Hello R-51 Pistol forum members
As you no doubt notice this forum looks different. I had to perform a major update due to some problems that were preventing the forum from loading.

Have always been interested in mechanical devices from cars, motorcycles and watches to firearms.
When I saw the terrible reviews of the initial R51 I knew I had to get it! I guess I have a soft spot for the underdog in my heart.
Just picked up my R51 last night its a GEN 2 Huntsville 2 tone. Looking forward to getting to the range with it.
Cheers

Johnny,
I have 8 mags, from '16 to '18. The only one I have not had to modify
is the 2018s. Are you having trouble with nose dives or failure to feed?
Pick 2 mags, shoot them and only them, at least 4 loads in each mag.
Keep a log of which mag performs.
And whether or not the mag was modified in any way.
It won't hurt to engrave numbers on the sides of the mag. That is what I do.
See what happens, send me the results on the log you kept.
I will see how it goes.
Also, remember do not use the slide lock to load the gun.
Slide the mag into the gun with slide locked back. Pull back on the slide and
release it. Then take the mag out and replace the round that is now
in the chamber. That will give you 7 +1

Quote from: sawatis on July 25, 2018, 04:12:02 PMI was thinking of ordering a +5% Wolff spring designed to fit a 7 round Kahr 9mm mag. I don't know if the coils will fit in the R51 mag though.
Well I had installed aftermarket Glock springs with a heavier wire...supposed to be a 15% or so increase... I lopped off one coil as the were way too tight and these work good. Now the new mags the folks at Remington sent me have 13 coils...and these have run without a hitch

This in the comments section of the hrfunk video on the R51 https://www.youtube.com/watch?v=r4HUNEfr-j0&feature=youtu.be
by user Big10. Re-posted because what we have been hearing from Remington and others is to remove a coil from the spring. The following discussion seems to make sense and suggests the spring isn't strong enough.

The problem is NOT that the mag springs are too strong. The symptoms your gun is showing is often too WEAK of a magazine spring. The round is escaping the control of the magazine under recoil (inertia of the round tries to keep the round in the same position -- an object at rest tends to stay at rest) while the gun and magazine are moving backwards. But the pressure of the spring is too WEAK to hold the round in the magazine. When the the round pops free of the mag, it will be IN FRONT of the extractor hook. The next round below comes up to the top of magazine, pushes the escaped round up into the path of the slide on return, causing the bind between slide, round, and barrel . This is true for both the "weird horizontal pinched round" and the "stove piped" round. if you remove a round or two from the mag, it won't have the problem since the spring has less weight of the rounds to push up, keeping sufficient pressure on the top round.
Three points: (1) were any of these jammed rounds UNDER the extractor when you looked? I'm guessing "no". And if so, then they were released from the magazine BEFORE the disconnector rail of the slide pushed the round out of the magazine. (2) If you download the magazine, does it ever jam like this? A downloaded magazine is often used to prevent jams when magazine springs are weak (think Viet Nam and M16 -- 18 rounds vs 20 rounds.) (3) The old axiom: first round or last round of a magazine that jams a gun is a weak magazine spring issue; the fix is to install a stronger spring! Want to reproduce the issue in another gun? Got a 1911? disassemble the mag and cut a couple of coils from the mag spring. Reassemble and watch the same jams magically appear. Quod Erat Demostrandum.
