    What cast bullets loads are you using in the ar15 9mm's

    what powder and bullet seem to be working in the blowback bolt type Ar15's in 9mm?
    Have the Lee 9mm tumble lube bullet and Unique, Bullseye for powders.

    the carbines ive loaded for, eat and shoot alot well including the 120 tc lee and 135 noe rnfb no groove and unique. never had much luck with the tumble lube 124 , they never grouped well enough to keep in anything tried them in

    What about the Lee 356-125 2R does it seem to be any better?

    I do load for my AR-9 , but can not get it to cycle with cast bullets, So I just keep feeding it 124gr, RN j=words and push them with unique or blue dot.

    I use the MP 358-135 over 3.8 bullseye, it works in 2 AR 9mms a Ruger PCC a Soumi a full auto uzi and other rifles and countless 9mm I get around 3” at 25 yards which is okay with me

    I have shot many thousands of rounds of cast and PC'd rounds thru my AR9. I use 4 grains of WW 231 under any one of several 115 to 130 grain slugs I have molds for. All work well. Have to say, the truncated cone designs seem to work best.

    blowback bolt type Ar15's in 9mm? It's a 'glock' (or what ever brand!) with a 16" barrel. Same 'rules' as a SA pistol.
    Whatever!

    yes, it shoot ok, but when PC'd, you have to load them shorter than id like because of that big fat nose

    I've shot tons of the ranchdog RF 135gr GC in my oly 9mm.
    I tried the Lee 124gr TC, but had leading issues with it in hardball alloy.
    I tend to push everything full house hard though,, lighter target loadings at just enough to cycle might have been fine.

    i shoot 3 mainly and would put another bullet through one unless its pc coated. (i hate clean guns and ars are dirty enough running as is) I have a group buy 145 gas check that can be a flat nose or hp that is the most accurate in both my 16 in and 4.5 in 9mm ars , second choice would be the 121 round nose rcbs bullet. Its proably the most accurate 9mm pistol bullet ive found and does real well in the ars too. Down side is its a 2 cav mold so casting is slow. third is another group by 125 plain base flat or hp mold. Probably 95 percent of my 9mm shooting in all platforms is those three bullets. but accuracy king in my 16 inch is that 145 cast hard with a gas check solid point and pc's when i was playing around working up loads had a 3x9 on that gun and shot 5 shot groups that went between 1 1/8 and 1 1/4 and thats an average of 3 5 shot groups. I would call that pretty darned amazing for a 9mm ar15. by the way its one gun i didnt build but bought. A cmmg. I dont think that gun has ever missed a beat either.

    I was asking about loads because I am a little at a time trying together the parts to build one, so far have a Blowback type bolt that is said to be for both colt and Glock mags. a 16-inch barrel and an 8oz buffer hope to get a stripped upper to build it on and parts needed for it, forward assist etc. going to take awhile, old man on a small income LOL
    So in the meantime just trying to see what bullet mold etc. to save for.

    I have found the truncated cone design (Lyman 356402) works really well in my AR9. The rounded edge truncated cone from RCBS (9115RN) is also very good and will not deform as much when seating. These designs feed well, are accurate and easy to cast. Require no gas check and lend themselves well to the 9mm case. Just 4 grains of WW231 push them with all the authority needed.
