Careful with that. You’re up there in pressure according to velocity. Wrecking some brass will be okay but I’d hate to etch my firing pin on a load that honestly is probably not safe with any moisture involved.

I water test my match rounds and will on my hunting stuff as welll, though I now purposely load fairly low because of it. Quite a few match shooters have figured this out after blowing brass on rainy days. Im shooting 42 grains of h4831sc on my 22 creed.
Is a water test as simple as it sounds? Just start low, wet your ammo and shoot it? Seems like a good thing to figure out before a hunt goes bad.

I normally make it as realistic as I can and shoot in the rain/snow.

Couple rounds wet by dropping in snow or set out in the rain.

Careful doing this. It’s going to wreck brass and at Rokslide standard 70,000 psi it’s not advised. Proceed at your own risk.

I learned about this the hard way on a hunt in Alaska. I was 1 grain under where I saw pressure and was blowing primers out on wet cases from river crossings. I pulled another grain out but haven’t tested to see if that’s enough. I don’t think it needs to be any harder than dipping it in water or spraying it with water.

I’ll load up 38 & 39gr. as well then and start at 38gr.

I’m not going to test it any higher than I have to. Just want to see where it gets dicey at.

I tested wet cases this evening. Sat the case head in water and they sprayed the entire case/bullet with water.

Went from 38gr. and 3180fps up to 42gr. and 3444fps.

The bolt a little lift resistance and click at the top, but nothing too too crazy.

I then went back down to 40 grains with a standard load and was still getting a bolt lift and click from just the residual moisture.

But I think 40gr. is a nice forgiving load.

You should absolutely come out to the MDT match in Arbuckle. It's a great match. You could shoot skills, shoot one day with the 22cm and one day with the 7-300.
I was JUST looking at the schedule and saw that one!

It’s the weekend after I get back from an aoudad hunt. But as it gets closer I’ll get a feel for whether I can swing it or not. If I didn’t already have that hunt set up, I’d just plan on doing it.

You would have to tone it down to 3275 as max velocity, something to keep in mind.

If you’re willing to do this to learn, I can imagine a match would be a really good time for you. Probably could shoot with some of the guys watching this thread too.
