Thanks gentlemen, M118LR is one of my go to rounds, so obviously then I would like 175gr FGMM if I can't get the other.
I haven't started handloading yet.

I've shot both the M118LR and the FGMM 175's thru USGI barrels and the FGMM was always the tighter group. I think that M118 will eventually be re0.placed by the Mk 316 Mod 0.

I suspect the improved groups from the FGMM... comes from the neck.

Does M118LR use neck sealant ?

Also, I remember reading that FGMM brass gets extra attention in context to uniformity and is carefully annealed.

Any truth in putting M118, M118LR back in the bullet seating die to break the neck sealant weld to obtain more consistent neck tension? Thus improve accuracy?

From what I have seen the sealant in the M118 remains very tacky.
With the old WWII AP that worked fine.

This is commonly called cracking sometimes it works sometimes not, depends on how old the ammo is and how much goooo is in there from the start.

Thanks from nf1e

For as long as you have been shooting there is a special place where people go and fry when they die for the guy's that don't.

Shame, shame on you. I will pray for your soul.

Thanks from nf1e and NWDave
