Looking to pick up some bulk 5.56, I been looking at the m855 simply for the 62gr reticle I'm running on a leupold. What I'm wondering is Should I save a few dollars and go with some of the Xtac PMC m855 or just grab the federal made ammo for a little more? I've heard pretty good things about Wolf Gold being decent quality too.
 What are you guys shooting for commercial bulk ammo and how do you like it?
How much difference in drops could one expect from the 55-62gr?

55 falls of quick past 300 yards.  

To me, M855 reticles are of limited utility because past 300 yards, you're gonna need a big ass target.  How much area firing do we really do??

I shot around 10K rounds of X-Tac in a little over a year and it's every bit the equivalent of XM855 or 193.

The BEST M855 is still just plinking fodder....

Stock up on XM193 or a good 55gr bulk. Then calculate the drop on your reticle for the new ammo. Good 55gr bulk will much more accurate than 855.

I agree, I'm just thinking  more quantity would be better than a little of higher end loads. If there is a medium grade quality round thats reasonably priced point me the way.
I been able to hit a steel plate at 4-450 using m855 and the holds on my SPR reticle. That was kind of where I wanted to get distance wise, 0-400 yards.

What could a guy expect in drop and accuracy beyond 300 running 55gr and what are good 55gr rounds?

If you want to keep your 62 gr reticle, stock up on rounds like t556tnb1, tap barrier, or black hills 62gr tsx


Almost any 55gr is good for practice and plinking, though i am partial to federal xm193

Drop depends on velocity, bullet weight, barrel length, etc.

Shooting 55gr AE223 the velocity from my 16" barrel was chrono'd around 2860 fps at muzzle. Using a 50/200 zero.:
300 yds - 9"
400 yds - 27"
500 yds - 58"

YMMV.

Get the Strelok app for your phone. It will tell you all of this. You will need to chrono your loads. Factory info can be misleading. I used the Strelok app for my 75gr loads. I confirmed it out to 600 yesterday. Very accurate.

I'm not married to the mk4, actually thinking of going ACOG eventually. My intent was to make solid hits at 400 and maybe beyond,

I'll have to grab some of that black hills to try. but mostly want some bulk for now while things are decent.

I like XM193 to stock up on and plink with. Usually have a few boxes of the federal fusion 62 grain around in case I need a better bullet. Shoots pretty similar to XM193 out to 200 yes

Depends on how close your setup is compared to what the reticle is calibrated for. You need to know what Leupold used for their reticle, IE:  Barrel length, optic height above bore, and muzzle velocity.  

This is dope for a flat top ACOG calibrated for M855, shooting M193.  

For a Flattop 14.5" firing M193:
Sight in at 100 per your manual. You'll be a half inch low at 300, 3" low at 400, 9" low at 500 and 15" low by 550. Once again, the 55gr loses gas fast past 300, so there isn't much you can do here without making your near zero absurdly high.

If you want good M855...

The ONLY thing you should be looking at is IMI M855 from Wideners or sgammo.com

Both outfits are GTG.

I would not get out of a MK4 variable to go with an ACOG.  Leupold can likely do a reticle and/or turret change and make that scope do whatever you want.  I used to be an ACOG guy, but since going low power variable, I'll never go back...

Hey thanks, Really appreciate it. I'll have to give those a look see. I'm happy with the optic over all, SPR is a little annoying at times tho.

What do you mean the SPR is annoying at times?  The reticle?  I'm thinking about having a Leupold 1.5-5X built for me with CMR turrets that are just 1/4moa and an SPR reticle.    I usually shoot a 1.5-5X VX3 with a duplex reticle and I do ok holding over at 300, but I'd like a little more precision at 300.  I zero at 200...

SPR reticle, I'm running the 1.5x5. zeroing at 100 next hold is for 350  so kind of odd subtensions, I like the ranging side of it tho.

Looking online today was gonna grab some higher quality heavier rounds but all were sold out even xm193. I don't know if I wanna go down the wolf gold road or not.

You should try Australian Outback 69gr SMK.  It will fly pretty close to  M855 and be a lot better ammo.  sgammo has it.

came across the AO69gr SMK thread, Nice shooting. I may have to order some of that up. price is right for a heavier load.
