my 3rd time with my LMT! I shot LCM855,Santa Barbra SS109,Wolf M193,S&BSS109,Black Hills Blue box 75gr. and even Blue Box 77gr.
All feed great!

HOWEVER I just found out when I load a round of BH77 and eject the mag and then pull back the charge handle it would be stuck and took alot of effort to eject the 77gr bullet?

I treid several Blue Box 77 rounds and all did the above?

Hard to eject by hand? it would seem FROOZEN UP?

All other rounds are just fine!

And it also feeds/ejects Blue Box 77gr while shooting?


Im thinking maybe its the Bullet itself since no other ammo has this problem!


Thanks Guys for your help on this one

I talked to Paul @ Bravocompany.

And Gene Swanson@ LMT very nice guy!

We think its the 77 BH Blue Box? might be the brass out of specs on my BATCH OF AMMO That I have?

since Lake cityM855 ,Santa BarbraSS109,S&BSS109,Wolf M193, and Black Hills 75gr,FEDERAL 69bthp
ALL ARE FINE!

still I hate to blame ammo since Black Hills is my favorite ammo company Besides WOLF

Might need resized a bit? or neck trim

Dano thanks that is good advise!

Gene said that they are good guys to deal with and to send my left over ammo to them?
I think I got 5 boxes left of the BB77gr.

I would love to trade in for the better 75 blue box because of the better bullet/crimp

Dano  Btw the Blue Box Black hills 77gr. works in my Bushmaster A1 shorty? wich I should of tried out sooner? Also it shoots out to 220 yards fine. 1/9 twist  14.7 ish  HBAR cut down by Kurt.

 Lets say all rounds were doing this? what would that mean?

I took arpart clean everything twice!

I found out  it only sticks with the Win Brass only?

the LC Brass 77gr. manually ejects just fine?

But the strange thing is that they are fine in my bushmaster?
