Have had my new JM Pro 24 out twice in the last two weekends so figured I should post a range report. For reference, date of manufacture as shown on the box was 6/2014. I did a full detail strip, cleaning, and inspection before lubing/reassembling according to Jerry M's video on YouTube. Installed a couple of goodies - the OR3GUN Marine Spacer Tube and a Limbsaver Airtech 10809 recoil pad. I had read the recommendations on doing a 100 round or so break-in with hi-brass rounds but decided to forgo that & see what happened with low-brass loads instead.
Last weekend, I headed out with my Brother Steve in wet, foggy conditions with on/off light drizzle. Using our Champion WheelyBird powered thrower, I shot about 200 rounds of cheap Herter's #8 1290fps field loads I had scored from Cabela's for $45/case of 250. My JM ate it with no complaints and in fact had zero issues except for choke tubes loosening on both of our guns (Steve has a JM 24 too). Yesterday, we got out again and shot another 200 rounds each in dryer conditions, again with no issues except for choke tubes loosening once again on both of our guns. Would some Blue Loctite used sparingly be the ticket to preventing the choke issues?
FYI, my brother has had his Pro since September and followed recommendations to break the gun in with 100 or so hi-brass slug/buckshot rounds. Since then, he has been running cheap WalMart Winchester/Federal bulk packs of 1200fps #7-1/2 to #8 shot field loads with no FTF/FTE issues. He now has over 1000 rounds through his - detail stripping/cleaning/lubing every 300 rounds. We also replaced both of our stock front FiberOptic sights with the HiViz CompSight Mdl. PM1002 and are very pleased with the way the much brighter HiViz sights stand out.
Cheers - Dave & Steve
