Racerx211 Posted February 14, 2013 Share Posted February 14, 2013 I Just got my new M4. This is my first shot gun and first non H&K gun I own.... I really want to properly breakin the gun with the right ammo. I called Benelli and the lady told me to use 3" magnum shells and to clean the gun first before shooting. I went looking for ammo and ended up buying Federal power-shok 3" magnum buckshot 15 pellets 1210 fps. Is this good ammo to breakin my new M4? I am not real familiar with shotgun ammo and want to make sure I get the right stuff. Also should I run some slugs through it as well? Thanks for any feedback.

Sukhoi_fan Posted February 14, 2013 Share Posted February 14, 2013 Welcome Racerx211. I'd advise against using slugs unless you want to be cleaning lead out of the barrel. Those 3" rounds will be fine for breaking it in. Be sure you lube it all well (including the recoil link on both ends and except for the pistons) before you shoot it.

12508 Posted February 14, 2013 Share Posted February 14, 2013 3" Magnums? That could get spendy. All you need to do is get the bolt dripping wet with the lube that came with the gun and shoot a whole 100rd value pack of federal birdshot that you can get at walmart and you will be good to go.

Sig Arms Posted February 17, 2013 Share Posted February 17, 2013 I bought a M4 yesterday and bought (200) 12 gauge Federal Power-Shok 3" Magnum 1.25 Ounce Slugs today for breaking in the gun. Now my only worry is breaking in my shoulder. Quote Link to comment Share on other sites More sharing options...
M4-Desert Camo Posted February 17, 2013 Share Posted February 17, 2013 I too have been firing just slugs as that's all the range will allow. I'm sticking with what ever I can get, mostly Winchester hollow points, 2 3/4" no 3" at Walmart. Got a case Fiocchi slugs I haven't fired yet (probably tomorrow).

Sharkey Posted February 17, 2013 Share Posted February 17, 2013 Just as a note guys, although the Federal Truball 1600fps slugs can be dirty, with my shortie 4x scope on my M4, I am shooting 5-7 inch groups for 9 rounds at 100 yards with the 18.5 barrel length, Improved cylinder choke and Briley Door Breacher Compensator and I am NOT taking 2 minutes in between shots or any long span of time. I am probably putting all 9 thru in under a minute which (I would guess) is repectable at that distance. Certainly not in my AR10's class but I'm happy with it and confident if I need to take a critical distance shot when it's all I have handy. Fed Truballs are made for smooth bore shotguns and although I've tried some of those sabot slugs, I'm not liking them at all due to the shape of the holes in the targets which indicate they are tumbling. Fed truballs have been right on the money for me and all I will use in it for slugs now. Slugs are all they will allow at my range as well unless you are shooting clays.

XTrooper Posted February 17, 2013 Share Posted February 17, 2013 These days, I usually hire someone to shoot my 3" Magnum loads for me. Quote Link to comment Share on other sites More sharing options...
Sukhoi_fan Posted February 17, 2013 Share Posted February 17, 2013 These days, I usually hire someone to shoot my 3" Magnum loads for me. I hear that. And not only with respect to recoil, that extra muzzle flash is a problem as well. Quote Link to comment Share on other sites More sharing options...
