    RMR 69 gr OTMs

    Here are target photos. Targets shot from bench at 50 yards. 10 shot groups unless otherwise noted:

    Pic 1. left side targets shot with BCM upper w/Burris on 6X. Right side pics with DDV2 w/Aimpoint Pro (and old ass eyes!)

    Top targets: Russian Steel 55 FMJ
    Mid targets: Fiocci 55 Gr SP (8 each)
    Bottom targets: RMR 75gr over 24.5 VV N140, mixed unsized brass



    Pic 2: both middle target shot with BCM upper gun w/Burris 6X scope and RMR 75 gr. 10 round groups.




    So from hereÖ

    Iím good with these RMR 75 grain rounds and the load. I will load out a couple thousand for use and to replace the M855 I have sitting in some pre-loaded mags.

    I never had a nice AR triggerÖwow! Getting another CMC. If I had that trigger on my BCM with the scope, I am convinced the groups would have been even better..with a factory duty grade 16Ē barrel.

    I also really like that DD grip for put on the DD. Gonna get one for the SOLGW lower.

    Man the Russians make some bad bullets. I remember subbing components into Herters steel cased ammo. And everything about the ammo was good except the shitty bullets. I could sub in a 69 gr OTM in place of the 62 gr bullet, and have nice ammo.

    I canít complainÖmy neighbor gave me 4,000 rounds of the stuff when he moved back to CA. Shoots good enough to get started sighting inÖand for short range matches.

    For sure. People always bashed the Russian ammo as cheap junk, but when I tore it down and weighed charges and stuff, it was pretty good quality. The bullet was the weakest part.

If that powder is as advertised, it would be perfect for shooting to 600yds off a progressive with a regular AR, which happens to be what this bullet seems well-suited for.
    I might have been overly optimistic about it being suitable. Hodgdon marketed it for .223, but I just sorted their load data by cartridge and powder, and every .223 load they list with it for 55- 75gr is compressed. Maybe itís a marginal powder, at best, for the cartridge. Iíll try a different powder when I get around to loading these 69s.

    People used to report pretty extreme variations in velocity. Donít remember if it was lot-to-lot, or within the same case. I think sometimes they used fairly shitty powder in general, and with the different brands mostly just being different importers, it was probably difficult to consistently figure out which was good and which wasnít. Other than the steel case itself, any of the above probably could contribute to its reputation for weak cycling.

    Iíve only chronoíd Tula, and it was shockingly consistent. Better than any brass cased 55gr FMJ Iíve chronoíd. I also was hitting reduced silhouette steel with it at 400 (donít remember which) with a gun zeroed for 68gr Frontier, easy peasy. The rims rip off sometimes, and sometimes the case sticks pretty hard. For functioning, my Hodge hates it the most, but Criterions donít particularly like it either. Colt and BA donít give a shit most of the time. I flip the selector 180* with it on a couple poor BA barrels.
