    From a reloading standpoint I have been using the following;

    9mm - commodity 124 gr round nose
    38 Super - 124 HAP
    SIG 357 - 125 flat nose

    I am wondering if I could consolidate all of that and just use these and wanted to get thoughts from you guys. Here is what I am thinking I could consolidate to;

    RMR - 9mm 124 Gr RMR FMJ Truncated Cone Flat Point MatchWinner Bullets

    All three of the calibers you listed are .355 bore diameter. Even the 38 super which gets listed from .355 - .358 is now mostly .355. So if you're happy with the performance of the new chosen bullet, I say give them a whirl and check out the accuracy, speed and Pressure. As long as they feed, if all OK, you have yourself a winner. I too have been consolidating my reloading components, but I am often gifted so much powder, primers, brass and bullets from former reloaders, I keep finding my self with odd ball components, but when it's free I can't complain.

    The .357 SIG with its short neck and long OAL is the clanger. It needs a rather blunt bullet.
    Will the RMRs seat deep enough?

    Good point. I load a lot less of the SIG 357, but I will check that.

    I consolidated 38 spec, 357 mag, 38 super all to 0.357 all to 125gr XTP's picked up some 140 gr XTP's to play with.
    I have a 9mm barrel for my Guardian if I ever load 9 it'll be 0.357 if it plunks.

    I would call those virtually identical, wouldn't you?

    Left is a 125 gr for SIG 357 and the other is a Barry's 124 9mm flat point

    I think generally you could do that, although most 9mm will prefer a .355 or .356 - moving up to .357 might cause some pressure issues.

    How do you like Berry's? Never tried plated bullets.

    I really like them and have had good luck with numerous loads with Barry’s bullets.

    Is there a lesson here? Quote from Big Balls McGee, No most of them just got too old , one of them I do all his loading for now as he never really got the hang of it, and a lot of the stuff I get is from their widows. It's good to be the known reloader in the area in that regard.

    I load that RMR 124 Match Winner in my Super .38s and my 9mm.

    Works great in both.

    I find them to be a Superb projectile.

    I have a friend who I fixed an M1A1 Thompson for, then his TRW M-21, and after he shot some of my hand loads, he shoots my 7.62/308 ammo almost exclusively. I just got a huge box of unused 9mm bullets. Personally I just like shooting his Giles gun every once in awhile. Last project has been going through his M1 collection and going type and type II bedding on them after finding NM parts. Used to have a huge box of M1 NM parts I pulled off some hurried arsenal rebuilds that went overseas. We refurbished them, so I made the point of "replacing" the old NM parts with new issue parts. Funniest of all, 95% of 633 of those rifles had sat in storage unused in a dry climate! :)

    Well I'd prefer to standardize with something like a 124. Finding jacketed is a PITA at the moment. I'll ask an old Aderdeen buddy what thinks and possibly give them a try until I can move back to jacketed

    I've used these with great results in all three calibers.
