After having some unexplainable misses, I decided to do some more formal testing with my MP5SD. I've heard these are ammo finicky, so I wanted to flesh that out and sort of decide what this gun likes and stick to it.
DJG MP5SD with a TPM can. MKE magazines, Primary arms micro dot on a B&T low rail.
Distance: 25Y, fired off of a front rest
Wolf WPA Military Classic 115gr
American Eagle red box, 115gr.
Speer Gold Dot, 124 gr carry ammo
Handloads - Berry's 124gr
Blazer brass 115

The method I used was to test them all and then circle back to the contenders when the gun was warm, so I would get an idea of what shot best throughout the spectrum of running the gun.
Wolf was first. The first eight rounds pounded into less than one inch, most on top of each other. (target 1)
Speer gold dot - Amazing. 9 under an inch with one right behind it. Again, flat out amazing. But at that price I expect so.
Rem 115 - severe impact shift noted from the others. Group was meh...
Blaser Brass 115 - Most within an inch and a half.
WWB - Terrible, with unexplainable flyers.
AE 115 - Pretty damn nice. 9 under an inch with one right outside that.
Berrys 124gr plated. These shoot amazing in my standard MP5 gun so I decided to try them here. Nope. Never again. I was astonished at how poorly they shot. This is a pretty hot load with an S&B primer and 6.2gr of alliant power pistol.
I circled back around to the AE 115, Wolf and the Speer, just because I liked what the Speer did so much and wanted to see if the gun being hot affected it.
It didn't. Similar results.
The wolf opened up a decent bit. I had high hopes of getting off cheap but it wasn't to be. The can worked loose on one group so I discounted it. The AE however, hung in there with the same POI all the way through.
I even removed the suppressor, tapped out some carbon and then reinstalled it and re-tested POI of the AE. There was no remarkable change.
I adjusted zero for wolf at this point, but I'm probably thinking that this gun, for what I have into it ought to eat better. If I'm not going to feed it steak and lobster (speer) at least I can give it a decent meal of AE.
Take a look at the attached pictures.
What's the hive say - Which would you go with?
