Been refining a little more. Messing with oal crimp and powder charge. I am up to 6 MOA. With a slight flier about every 15 rounds or so. .18.7 grain. Starting to show a little, still in the normal no worry range, pressure.
Actually had a better accuracy shortening the length up a bit, creating a longer jump then anything so far.
Function is now flawless. Stepping up to 19 grains. Loaded up 30 so I can get a good sampling. Think this is as fast As I want to go with this.
Way different experience then anything I have tried to date.
One thing, I am pretty sure of, is I have the alloy and size right.
I have Definatly learned that load development is not a one method solves all thing.

Have to take this one as far as it will go for me first. We will see what that 19 grain gets me first. 6064 may be next up.Soon as I get my Handler to allow me some range time. :)

Ps used wife's phone, auto correct changed no worry, to now worry, have bit it to go yet. As far as pressure goes. It's getting close and I think 19 grains may put me real close to hot for this combo. But not there yet.

yeah,, your kinda in a box with the slick side, plain base, and the ker-chunk machine your using as a platform.
there's a lot of little things going on all at once and they all contribute to the success or fail of the whole package.

Ok we are pretty much set a 19 grain. at 19.5 it turned into a scatter round and left lead in the throat. From 18.2 to 19.3, pretty much getting a nice 3 inch MOA.
19.5 gives me MIA's

Loaded some last night. Messing with variables in PC. Plus small changes in oal today, or as soon as I get back out.
Will do some target posting later. Think I have hit that first accuracy node for jacket, data pretty much lines up, but go hotter I hit the fence.
After I finish fiddling with this I am going to load up 200 or so for practice, then head on still using 335 but with Tommy's suggestion of a gas check. If I can figure out what ones I need for a plane base at.224IMG_20210510_094845705~2.jpg
Here is what is up to bat.

well you'd need plain base gas checks.
I don't know of anyone making them though, unless it's someone at home doing it, or someone is selling a tool to do it.
I guess it just depends on which tunnel you want to follow.

The only commercial producer of PBGC I have heard of, is Sages. But they don’t seem to make for .22. So, a tool might be the only way; Pat Marlin makes checkmakers for more or less everything. Or maybe you can find a clever way to make a few, using a .22-something push-through sizer, and a push rod of slightly reduced diameter?

I’ve had a .30-cal PB check maker for a while, and have shot a bit with different loads. My observations so far:

- PBGC added to lubed bullets increase tolerance to about the same level as lubed bullets with regular GC (like 1800 fps ballpark. Results are very similar with PB, PC bullets

- Adding a PBGC with PC on top does not, however, give a drastic increase in tolerance; around +5% powder charge or so, compared to PB/PC.

Thought about trying to make a punch. Need to do some research yet. Well we will cross that road when we come to it.

you'd have to punch them open and then fold them in place.
might be easier to punch down some 24 cal. checks in a tapered die and leave the sides long.

Not as nice and clean as yours but I am getting there. May end up going to a hot plate like others. Have great bases and am getting more consistent in weight variation. Still get a few very minor wrinkles with those 22's, But so little, the powder and sizing wipes them out.

Well took those out and shot them then decided on the best combo. Loaded up 25 more and went back out. Shots prone with sandbag at 80 yards. Could not get back to the full 100 as the bench was flooded out.
Best 3 out of 5 groups. Ps ignore the 100 yard note. I put that on there before I went to the range, these groups were shot at 80 yards.

Did this prone and bagged, but as you can see I still managed a flier. The other 2 groups I shot were without a bag and came out at 5MOA, my shakyness to blame.
Will post my load data for this work up, as soon as I get my notes.
I think any improvement in this might come from better casting. Or better shooting. LOL
But ready to cast and load up 500 at this. Figure this is, about as good as it gets for me at this point. Pretty happy with 2 to 3.25 at 80 yards.
That is a consistent 4 MOA or better. I am very happy with this as it will serve good as a 50 yard practice, and close range on the move, drill round.
I set my scope for the round but wrote down the clicks to get it back to jacketed.
