 Load Testing -> Best results = unburnt powder

I'm switching to Ramshot XTerminator and did some load testing. I loaded 10 rounds of 23-25 grains in .2gr increments for a total of 11 sets. Using Wolf/Tula SR Primers. Went to the range and shot them all. Scanned all the targets and used the on target program and got the following results:



Now the best choice was 23.2 grains which has performed flawlessley except for one thing: it leaves unburnt powder all in my upper receiver and a little in the barrel. I saw it the last time I went shooting earlier last week and had a couple light primer strikes but didn't think anything of it. I had a match today and things were starting great no issues, but then towards the end I kept getting light primer strikes.

Took the rifle home and there was a fair amount of unburnt powder in the upper and I'm thinking that the powder is starting to get around the hole in the bolt face where the firing pin protrudes and it's slowing down the FP's momentum.

So I've never ran into this issue because H335 used to work until this whole wolf primer issue. So is there anything that I'm doing wrong that's causing unburnt powder? Does this mean I need to up the charge (possibly 23.6gr)? Does this mean it requires magnum primers?

Any advice would be most appreciated, thanks in advance.
