I shoot 124 gr so can't help you A great deal within the a hundred and fifteen gr however the precision Delta do Have a very form of hollow base as the base is form of recessed. (not sure it helps make any variance but hollow foundation is an effective advertising and marketing gimmick anyhow)
You may also check into Precision Delta as they have normally had good quality FMJ 9mm bullets that always shot very precise for me.
I eventually received mine drilled adequately with straight bits. P80 experienced despatched me a substitute body and it way too arrived with warped bits.

These "developed" AR-15s involve ZERO frame ending. Indeed I am aware There's also P80 AR-15 frames. But, I'm talking about the serialized lowers which are turned into working rifles by obtaining and setting up all the areas.

All referring to those assignments as "builds." And, there are zero frame ending or modifications. Only a make a difference of assembling the parts. Will you be detrimental Nancies more than to the Black Rifle Discussion board chastising the posters there about whether or not they are "definitely building" anything?
This way you won't need to have a probability of bending or breaking something or enlarging the body holes. Also you won't need to hammer the pin out when you need to disassemble the gun.
I am conscious of that, my means of referring to your post. By no means explained he was. Continue to a heavy handed approach that does not deal with the fitting dilemma just overcomes drill size chart it with pressure. Which is not likely gunsmithing.
one. The pin wouldn't go each of the way through the rear rail module gap on the right aspect. The pinnacle of the pin is essentially flush Along with the exterior facet in the RRM.
