New Mossberg MVP Scout first shoot

Hello
Picked up a new scout rifle yesterday and on my out I bought two different boxes of 7.62x51 ammo.. PMC Bronze 147gr FMJ and some PPU 145gr FMJ for the initial sight in and plinking.

I pulled down one round from each box and discovered;
PMC.. 41.8grs of a ball powder
PPU.. 44.8grs of a ball powder

Velocities were taken with an Oehler Mod 33, skyscreens centered 15 feet from muzzle.
The velocities are virtually identical.

So my question is are these velocities what I can expect from "M80" type ammo from a 16.5" barrel on a bolt gun?
I have some 149gr FMJ bullets I would like to duplicate this load and do some tuning to find out what the gun likes, and would this veloctiy be what I would want to think about stopping at..

The gun obviously doesn't like the PPU ammo but the PMC is better than I expected..

Thanks

Thanks from Dougboffl

I would run a box of 165 gr or heavier hunting type bullets out of it just to see. Do m14 mags really work good with this rifle as advertised?

Hello and thanks

Yes, M14 mags do work.. Kinda cool.. In fact the magazine that came with the rifle is this one..

Magpul PMAG LR/SR Gen M3 Magazine LR-308, SR-25, Ruger Precision Rifle 308 Winchester Polymer

I will do a break-in and work with heavier and better bullets soon, but just wondering about this M80 ammo and how to duplicate it..

Try Hornady 150 FMJBT with LCLR brass and 42 gr IMR 4895. Good approximate M80 load.

The old standby as above with 168 SMK works better. 41.5 gr IMR4895 and same brass.

Both work well for me depending upon how my day goes.


I am told the Nosler 168 hunting bullet works REALLY well . It has a BC of .490...if my memory still works. :o)
