    I contacted Tech support at Hornady to get an idea of what to expect from their 22 WMR
    45 gr FTX Critical Defense ammo when fired from the CMR... I share the response with you.

    Did you pick that up at Clyde's? They had some the other day, I have so much V-Max I passed on it as it was almost $17 a box.

    Hey all!
    I got lucky and sportsmans guide had this in stock with no limits. Needless to say, i bought all i could afford haha. hoping it will run good and perform well in my CMR and PMR. Will post results once I have them. I plan on a chrony comparison too if it performs well enough to justify it.

    I picked up a small quantity for use in my CMR, but I'm going to sit on it until after I've read your results... what barrel does your PMR have in it?, mine has the 5" threaded barrel.

    Parabolic drop. If you shoot up a little, it will come back down and cross the original muzzle line at some point. Here, that is at 100 yards exactly.

    Or more precisely, this gun was probably zeroed in at 100 yards, making it high at 25 and 50, and low at 150, but dead on at 100, because the scope settings make you shoot up just a tiny bit so that time it gets to 100 yards, its right back where it was from gravity. This is mostly just velocity. All objects fall at nearly the same rate, barring a microscopic bit of variation in air resistance (for bullets). The faster a bullet moves, the less *time* it has in the air at a given distance for gravity to have affected it. That is all you are seeing.

    My PMR has the second gen (non fluted) non threads factory barrel. Hope to hit the range tomorrow if weather allows. Most likely will be the trip after that where I can chrony (mainly want to function test and loosely accuracy test before going into deeper).

    I don't know if it makes any difference, but the calculations Hornady came up with are for me using an EOTech 1 MOA red dot without magnification.

    Any range updates on this ammo?

    I've been working out of town for a few months and stumbled upon 10 boxes of this ammo for $13.99 each. Needless to say I left the store with all ten boxes and will let you know how it performs in both my cmr and pmr in a few weeks when I return home.

    I would like to know how well it groups and if your using a scope how's it perform at 100 yds

    I can't give a field report yet, but cooler weather in the next month or so will change that.

    Sorry for the necro post here, though would love to know the results here. I would love to find ammo that is subsonic and cycles the CMR30. This gun screams SBR and run a can on me, but bought it knowing this wouldn't really be a thing for me unless I could run subsonic ammo.

    that sounds like a case for tampering. See if you can reduce a spring somewhere so the lighter ammo cycles, but it has to snap back forward well enough to feed, meaning polished internals and mag lips as well. I don't know if it can be done. Alternately look for extra heavy projectile slower ammo. I forget if cans drop the velocity some (?) … I refuse to pay a tax and register one, so almost zero experience with them. Ive made subsonic ammo for accuracy, that isn't hard to do, but getting it to cycle without handloading your own makes for some challenges. If you really wanted it super bad you could tear apart commercial ammo for the primed cases and rebuild it.

    You have to kind of think about this for a second. The 40 grain 22wmr bullet is basically the same as the 22lr bullet right? And the reason the 22WMR exists is to kick that 40 grain bullet to higher velocities. If you drop it back down to subsonic you are recreating one of the 22lr cartridges, completely negating the reason for shooting 22wmr. This is why you don't see subsonic 223/5.56 either. Because it's more or less a 22lr (granted its 55 grain though).

    For what it is worth, there is subsonic WMR ammo... just a random link here, not advocating this retailer: https://www.mackspw.com/WINCHESTER-22-WMR-45GR-JHP-SUBSONIC

    Also this Hornady, though I'm not 100% it would be out of the CMR-30. If Kel-Tec made a carbine version of the CP-33 I would be all ears, though on the same note being able to drop subsonic ammo w/ suppressor, then swapping mags with regular WRM is highly appealing to me.

    A little google-fu reveals I'm not alone here.

    I did order some of that Winchester (not from the above link), though haven't been to the rage with it yet. I don't expect spectacular results, though if I could find a good line on parts, I'd be temped to experiment with spring swaps, ect.

    So that Winchester is a no go unless you are looking for an 'unreliable bolt action' to be fair it did work just fine shooting and the cocking it back on every shot to load the next round... I just can't recommend that. Unreliable may even be a bit too much as it did work after each manual pull and release on the charging handle.

    Not sure why I thought this Hornady was subsonic... It is, but only in short barrel revolvers / pistols.

    On the other hand this is the most reliable ammo I've found for the CMR and it isn't that much more expensive when you buy 500+ round boxes.
