Just finished a detail strip, degrease, and clean then Frog Lubed it inside and out. Taking it out in the morning and will put it through the paces with a few hundred rounds of target shot from assorted brands. Can't wait to get out there and heat it up a bit...

I am more of a pump guy, but that is one sweet shotgun indeed. A semi I might seriously consider, let us know how she works.

Got out early this morning for the first range trip with the new JM Pro. Bit of a heads-up, many 930 models don't function well with any ammo rated at muzzle velocities under 1200 fps. My 18.5" 930 Tactical is great with buckshot, slugs, and any high brass, but won't eat any low brass ammo and chokes on most target shot even above the factory recommended 1200fps. I have been hoping the longer barrel and the enhancements to the JM Pro models would cure this, so I picked up an assortment of #8 target shot and headed out with my fingers crossed. Happy to say that the new JM ate everything I fed it and chewed through 250 rounds without a single failure of any kind. Here's what I ran through it today...

25 rounds - Rio Game Load - mfg# BG288 - 2-3/4" #8 shot - 1280 fps
25 rounds - Federal Target Load - mfg#- TG12 8 - 2-3/4" #8 shot - 1200 fps
25 rounds - Remington Premier SST Light Handicap - mfg# STS12LH8 - 2-3/4" #8 shot - 1200 fps
25 rounds - Winchester Super Handicap Heavy Target Load - mfg# AAHA128 - 2-3/4" #8 shot - 1250 fps
25 rounds - Winchester Super X Heavy Game Load - mfg# XU12H8 - 2-3/4" #8 shot - 1255 fps
25 rounds - Estate Dove and Quail Load - mfg# GTL12XHN 8 - 2-3/4" #8 shot - 1255 fps
100 rounds - Winchester Extra Light Target Load - mfg#AAL128 - 2-3/4" #8 shot - 1180 fps

The 100 rounds of Win Extra Light had been sit'n around loose in an ammo can for several years and I was really expecting issues in the 930 due to the sub-1200 fps muzzle velocity rating. The JM Pro ran through them like me running through a brisket sammich.......and that's really fast. :D

I have to say the enhancements to this particular model are well worth the slight upcharge over the standard 930 models. The extended feed ramp, beveled loading gate, and shortened forend help a great deal with faster reloads. I was hand loading two shells at a time with no hang-ups whatsoever. The trigger is lighter than on my 930 Tactical and with the over-travel stop it can be tuned to your liking. The fiber-optic sight glows brightly and is very easy to reacquire during a fast string of shots. All said, I couldn't be happier with it...

The question is can you shoot it as well as Jerry Miculek? :AR15:

gun sane

I wonder how it will perform with #4 shot or bigger.

I've run everything from #4 to BB waterfowl loads in my other 930 without issues, but haven't tried any in this new one yet. It's running fine with the lightest loads I would ever need to shoot so don't imagine there would be any issues with heavier, hotter rounds as far as function goes. With the Accu-Set chokes there's enough adjustment to keep patterns nice and tight for my intended use...

Not a chance!

I'm fairly quick on target, but that man defies the law of physics...
