Ran some tests the other day indicating 300 MP is about 2% denser than Li'l Gun. Not much, but every little bit helps in the little bitty case!

Behind my house is a 1,400 acre cattle farm. In front is an upscale neighborhood. Shooting wouldn't be a problem, except for the noise. Not sure how the neighbors would take to that. I have a range around 3/4 miles behind the house, but it's pretty muddy right now. That far away, they can hear, but it's not objectionable. I just don't like to shoot in the mud, walk to targets in the mud. get my truck all muddy. My wife just hates to wash it and I don't like seeing her scrubbing heavy mud off the wheels, etc. If I gotta use 4WD to target shoot, I can wait... I've posted this picture before. You know how a bunch of cows love to tromp in the mud and make a big mess. And this Red River Delta mud is probably nastier and stickier than your OK mud... DF

10-4 and agreed on all that DF, and the cows WILL invariably every time stand between you and the target , I jump on that little Ford tractor out the back door, go staple up a few targets and let fly from the shop. There is no one within 3/4 of a mile here but me and Wifey.

My range results were interesting today. The load was the Tipped 30-grain Varmageddon in Winchester brass, already fire-formed in this rifle, with CCI 450 primers and three charges of 300 MP:
14.0 grains--3270 fps, .77 inch group 14.2 grains--3287 fps, 1.49 inch group 14.5 grains--3348 fps, 2.48 inch group Sure would like to see what a 13.7gr charge would do....

I'm gonna be shooting 45 gr. Speers and 45 gr. TSX's. I'll be dropping JB's 30 gr. load a bit. Could end up in the 13 gr. range. We'll see. DF

The 527 firing pin was indenting rifle primers too deep, almost to the point of piercing them. Mic had mentioned that happening with his 527 and took a couple of coils off the main spring.
I just did the same thing. We'll see how that works. I can always get another spring if I screwed it up.

Luck with the spring/pin adjustment DF, are you using the CCI-450 primers?
I started using them because I believe they have a harder more robust face on them, turns out, they are the most accurate in my rifle too.

Those weren't 450's, Feds I think.
Haven't shot 450's yet.

DF,
As gunner points out, 450's have a thicker up than Federal SR primers. The F200, in particular, has a thin cup. You might want to hold off on the spring adjustment until you try 450's.
I haven't had any problems with the firing pins in my 527's, but thicker-cup primers have proven most accurate in all of them.

Done done it... I'm sure the lock time will be slightly more, but so what. "What difference, at this point, does it make"...(H. R. Clinton) If I "done wrong", a new spring isn't a major deal... We'll see how it goes and I'll report. Thanks for all your help...!! This is an intersting project, for sure. DF

Gunner, seems to me 300-MP isn't as bad about sticking to the powder measure as Lil gun. I dusted the chamber with graphite and get complete delivery of each charge without "late" granules showing up with extra bumps with the handle.
I think I'm gonna like 300-MP.

I tried it today in the Bee, and got promising accuracy with 50's but a lot of velocity variation. I used CCI BR4's. There's a lot of air space in the case so I think 1680 may be a better choice for "heavy bullet" Bees
