rmr 9mm 124 gr matchwinner bullets

[pighunter284]

anyone loaded with these? I've never loaded a lead exposed bullet before. i know its a fmj flat point bullet. nothing in my 3 manuals for that style specifically. using titegroup starting at 3.8 maxing at 4.1gr. with COL at 1.060. I've seen round nose fmj at 1.150 in the manuals. i was thinking to start at 1.100. anyone with experience would be a great help. thanks

If the bullet is shorter than the std 124 FMJ then use same data and OAL. Check for good function. If it works shoot it that way. You may have to seat it a little deeper to avoid feeding issues. If so be careful and do not seat the base deeper than the 124FMJ base (keep same internal case volume).
