I won a can at a match got it after about a year and was very excited. I screwed it on a brand new barrel and took it out for the first time. First I sighted the 260ai in and let it cool shot my 6xc for a little bit went back to my 260ai . first round went low right about 1 1/2 the next round went where it was supposed to go and the rest followed . I let it cool and the same thing happened. I looked for baffle strikes there was nothing so I put it on my 6xc and the same thing happens first round flier later I put it on my 300 win mag and the same thing

Any indication of baffle strikes?

Who's can and what mounts?

I have a few rimfire cans that do this and I haven't found a real solution other than remembering and allowing for it. It's not 1.5 MOA though. That seems a little extreme.

No baffle strikes and it is direct thread.

My first thought is that it's not shouldering up 100% and the first round makes it settle

It does it when it cools down every time when it cools down on all of the rifles I put it on. I don’t know weather it’s the difference between the bullet traveling through gas vs air or something else.

Is the can loose? is the can and barrel marked for test purposes? Is there a end cap that is not completely tightened and moves?
I have seen shots all over the place due to similar issues. The can is an accessory, I would remove that and see if the rifle groups any differently. Also, on "cold bore shots" sometimes its the person behind the gun settling in...... My advice would be to make sure everything is the same, change one thing at a time to rule stuff out.
I'd be curious to know what it is when you figure it out.

Without the suppressor what does your rifle's cold bore shot look like? With the weight of silencer hanging off the end of your barrel, it could exacerbate your cold bore shot.

What barrel profile and how heavy is your silencer?

No can group
I would start with knowing that the weight of the can will adjust shot placement because it changes the way the barrel functions etc..... I would look at your attachment system to the barrel, torque spec if its threaded and also check the end cap. An easy way to determine if there is any movement is to mark the rifle to can and can to end cap. I would start there if there are no baffle strikes..... It appears with the group above you can do your part ;)

I’m getting the same thing with a can on two different 300 wm rifles, one a light weight hunting rifle, the other a heavy barrel. I think it’s something with the gasses or temp, as my cold bore shot is about an Moa high on both. If I shoot a group, put the rifle down to cool off, and shoot another group, I get the same results. When I keep the rifles warm, I’m getting consistent sub Moa groups.
I think next I’m going to try pushing some fresh air through the barrel, to rule out gasses. Any other ideas?

I have a SC Omega that does the same thing, but not on every rifle... still haven't figured it out, so im tagging in!

My cab is an omega as well. I’ve grouped on 2 300 wm’s. I’ll have to see what it does on some ARs and a 308.
Anyone try asking SilencerCo about this? I would assume they’ve done tons of testing.

I haven't talked to silencerco...
Mine hated my bolt action blackout, seemed ok on my AR blackout.
it seems to do best on my 300 SAUM

I have a rifle / can combo that is doing this. See thumbnail. I tested 3 different bullets, including a factory load. There was just a few minutes of cooling between each group.
Rifle: 6 Creed AR10
Can: Dakota Silencer Varminter 3.0, 30 cal

Whats odd / frustrating is that this same can / rifle combo did NOT do this initially. I want to say the first 500-600 rounds did not show this. Also, I use this same can on a Desert Tech, and it does NOT do this.
So what gives? Are maybe the threads on can, rifle, or both not lining up the baffles with the bore perfectly? Even so, why just the first shot of the group?

FWIW, the first shot of each group was very consistent.

Anyone find a solution?
I've heard of putting a little water in the can, but as I understand it, that's to help with 1st round sound supression.
