Guys,

Below is a picture of my brass. I am working up a load with the wolf .223 primers, the load is H335, wolf primers, 130gr speer hot cor, SSA brass, shot out of my 1/12 - 3 groove - DMR chamber. I don't have a chrono

From left to right is 29.5, 29.7, 29.9, and 30.1 of H335. I think on the last two you can see some very light ejector marks but they are pretty light...the primers I think look good. Can I keep going? I think I am close to max but want to go as far as I can and still keep it safe.

Tell me what you think

The 29.9 looks like some primer cratering that would indicate high pressures. It would be easier to tell with multiple primers at that load level. The 30.1 looks to be a lighter load by the looks of the primer so that makes it all the more interesting.

IMHO you need to try a few other rounds at those loadings. You might also look at different primers as those may be softer than some of the others available. It could also be those particular primers are a little softer than some of the others.

Others with more knowledge should weigh in here shortly.

30gr was my max last year and hit 2521fps. the 30.1 shows a complete circle where the brass flowed into the ejector hole, i wouldn't go any higher.

I get ejector swipes marks on factory loaded SSA (not combat) Pro Hunter loads in my DPMS that look like your last pic, but my primers & the rest of the brass looks good so I don't pay any attention to the swipe marks.

H-

That is what I was looking for thanks!

Describe where the circle is you guys see on the 30.1. By the First "s" in SSA? That the half moon?

Yes but, if you look it makes a complete circle froom the "S" up and to the left.

Ok I see. Thanks.

I agree the last one is your clear swipe and for a regular shot round dropping down from a couple tenths to a .5 grain depending on the temps it was shot at woudl be a good idea. That last load IMO is not bad just hotter than need be unless you have some specific vel goal/need. Not sure about the other specs of your laod but if you can go even a small amount further out in COAL that will have a good effect on the pressure. If you have any crimp at all loose it. Depending on the primer you are using you can try changing it.
