Wth! Which mold for an AR15?

[Lloyd Smale]

shot probably 50 of them that day and no leading what so ever. barrel looked a bit dirtier when looked down after that session then it normal does. I shot 5 jacketed bullets when I was done and it looked no different then if I would have shot jacketed all day. Some of the "dirtiness" could of just been from the fact I was using ramshot exterminator with the cast bullets. Its a bit dirtier then my normal loads using 2230 with jacketed bullets.

Hi sharpshooter,
thanks for your infos, and btw., pretty good German for a non-German.


@Lloyd Smale:
Holy cow, that´s a neat velocity from such a short barrel.

Did you see any abrasive signs/leading in the barrel.
Just thinking about, such a velocity and bad accuracy would show in this direction, not?

@all:
Found molds from Miha / MP molds, of which I´m owning some.
Pretty good molds so, think that could become my starting point.

Because of Scharfschütze´s intervention I´m a bit unsure now if I should go with 65 or 75gr. with my 1:9 twist barrel.....

I can´t stabilize 75gr. FMJ for sure.

I use the Lee 225-55-RF gas checked and sized .225 with NRA 50/50 lube, no powder coating. This is ahead of 20 grains H4895. I shoot these in an M&P15 which is 1/9 twist. One question would be what are you planning to do with it? I'm mainly doing tactical training no more than 50 yards so it works just fine for that. I don't need 1 moa accuracy for that.

I have the same mold as gamsek mp 227-65 fn
And it shoots great in my Sig 516 5.56 rifle
I gas check, pc , size to 226 and load to slightly less than 2800 fps and get Sub MOA
Get some from Gamsek . try them I think you will be happy with a little experimenting.

yup even with my results a 4 inch group at 50 yards makes it capable of being a just in case bullet for when or if I couldn't find jacketed bullets for my ars.

Yes, Gamsek pm´ed me and offered me to send some of his products, what I´m happy to confirm.

Thanks so far gentlemen, next step will come.

Exactly, I don't need to burn up the jacketed stuff, extra powder for training in mag swaps, keeping on target, etc.
