Just got an R3M, it’s a thing!
I just got an R3M .25 long. After 100 or so rounds it’s shooting quite well. With JSB Kings it’s making 950 fps with a standard deviation of 2.5 (wow). Groups at 50 yards look pretty good. Can’t wait to see what it’ll do at 100 yards. If I’m reading everyone else’s results correctly, 950 fps will end up being a little too fast for the JSB Kings…
The Magnetospeed bayonet style chronograph works well although it had to be mounted off to the side of the barrel.
So far, it’s a great gun. Thanks Ed, thanks Tony.

Demp, thanks for the stats.
Here’s what I’m seeing:
-typical muzzle velocity has gone up just a bit from 950 ft/sec as new, to 965 ft/sec after about 300 shots
-36 shots took the tank from 215 bar to 145 bar, which is about 2 bar/shot
-1″ groups at 100 yards seem plausible, but I’ve got to learn how to hold the gun
-love the repeater function, but could be smoother, I may polish the pin that pushes the hammer down as others have done
-the gun attracts lots of attention from the powder-burner crowd because you can shoot off of the back porch and not annoy occupants or neighbors

super! 5″ or 6″ longer than std makes big difference.
I’ve got mine shooting at 940 fps with the JSB 25s.found that to be optimum fps for accuracy out to 250yds. Up to 100 yds even 1000fps produced golf ball size groups regularly.
72 regulated shots with a 2.33 SD and max spread of 9fps.
If I open up SD and spread a slight bit I could claim 76 regulated shots but I stop count right where I see the drop starting.
Wait til you get a few thousand pellets through it. I’ve got appx 25k in mine now. Just keeps getting better.
You should see mid high 60s shot count if the reg,HST are dialed right together at 950fps.
Good question. I’ll post results as soon as I know

Looks nice. How many shots you can get with your long and 950 fps?
Beautiful gun X356b, welcome to the club!

My R3M .25 long is set for about 915-920, which is super accurate at the ranges typically needed (30-70 yds). This place is a jungle; the only 100 yd open space here is on the highway 😛
Your increase in speed could be due to parts loosening up/less friction, or your barrel may be building up some lead. The latter will be obvious, as your groups will suffer.
Congrats on the ‘pup!
