This one didn’t really fit in any of the other POI shift threads before… so… 
Nothing Earth shattering… but kind of interesting… Zeroed my SPS with the Brakeout mount for the SDN… then mounted the can. POI is 6/10s of a mil up. No windage adjustment… just elevation. Odd that it’s up though.
You getting good accuracy with the SDN-6? I considered the can for use on both my carbines and precision rifle, but ended up going with a Surefire 7.62 Mini.
Yeah. Accuracy is maybe even better. Hard to say for sure as .308s can be moody… shooting lights out one day and just MOA another.
But on Sunday it was stacking them a little better than normal.
Just out of interest, were you usng the exact same round throughout? Harmonics are difficult to predict, that aside could the causal factor be physiological based upon shooting grip etc. to compensate for the extra weight of the can?
I only run one load. I did sling a 3 rounds of Mk118 LR just to get the brass… but that stuff shoots same POI as my 175 SMK load.
No physiologicalities… I go to the Hodnett church of the loaded bi pod and rear bag divinity. 
The accuracy was crazy good. One five shot group was 4 shots in one hole, then one user error flyer inside an inch.
Then we throttled 500 yard steel in a rapid fire sequence that were dead center hits.
Maybe it increased the MV a bit so its dropping less?
0.6 mils is huge. I don’t think the .308 is capable of picking up that much velocity.
Mine is always straight down, never any windage either.
I must have misread that. Yeah that’s pretty big distance at range.
Can I hear an Amen!

maybe i missed it. did hodnett invent some technique for loading bipod and rear bag? what is he doing different?
Nothing different. The point was with a stable platform, shooter influence on the rifle couldn’t be 6/10 mil.
No. I was just making joke of the tongue in check religious reference to Todd. Whom I am a big fan of.

Amen!
heh ok i totally misread that
so is that .6 up pretty repeatable?
I’m sure it is… I’ve never had an AAC can that wasn’t… but I’ll have to shoot it again a few times to confirm.
That was its maiden voyage.
Funny. I just got my stamp back on my sdn6. Haven’t had it on the OBR to test POI shift yet. Just on my 8in 300blk with subs. Wow.

I disagree. This is one of the reasons I love 308’s. They recoil enough to exploit any deficiencies in the shooter’s firing position. I routinely see people’s POI shift .5 mils from POA when I force them to get up and walk around between shots. While they are walking around, I’ll take their rear bag out from under the rifle, and smush it around, and I’ll pick their bipod up out of the divots they have it in, and put it on virgin ground. Very common to see .5 mils deviation.
Do the same test with a 6.5 creed or other light-recoiling round and the deviation is less by half or more.
As for the suppressor shift, .6 mils is average I’d say. The fact that it shifted up, rather than the more often seen downward shift may be an indicator of a thread/mount problem.
That crap wouldn’t work on me. I’m angry anal about getting my platform back where I want it. You’d hear me cussing a friggin storm up.
