Well instead of sleeping like a sane person last night I had a little idea. Since this mold is supposed to be THE thing first standard 30cal .308 bore and the like...and my bear creek AR has a .308 bore.... Why not ?

The Lyman hand book was kinda a waste of time since it basically says don't waste your time with cast and semi autos, but looking in the Hornady hand book I saw that most of the loads where running. In the same ball park as what this bullet apparently likes for cast velocity soooo,did a little bit of a SWAG and decided 22.5 GR of accurate 2015 should be a good place.

Honestly didn't get super crazy with brass prep like I usually do because one I've only ever fed this thing steel cased and two ....I may have been half asleep at 1 a.m so standard, lube ,size ,trim champer all that goodness then expand with a NOE .311x307 plug. Then I just kinda fiddled around till I found a seating depth that would change the round with me using my thumb to just barely press the bolt carrier home.
Actually a little surprised but these need to be in kinda far

And today's set up. 50 yd( why 50yd ? Because apparently that's what your supposed to test cast at for some reason, it's what all the books do and it's what everyone else lese does , gotta say though seem every time you start doing good at 50yd people say go to 100yd then 200yd or talk about how you would really only need to do it at 50ys so smirk this is a 75yd brush gun anyway so ) feeding from the mag , front rest rear bag 1-4 monstrum LPVO, magneto speed Chrono which I must say, isn't the biggest fan of cast lol, she's a lil picky
[Linked Image]
Now I gotta say I wasn't expecting much but after the first 6rd of getting on paper I don't have ANY feeding issues, as far as the bolt not catching or picking up, did have to mortar the charging handle though but fixed the seating depth a little to hopefully alleviate that. But guys when I got on target !
First three rounds at 50 after getting some what zeroed, only read two of them right though

And the next charge level up

And why don't you call it an AR-10?

Why your hands white?


swampgas chili and schmidt beer makes for a deadly combo

You have to remember that 1 out of 3 Democratic Voters is just as dumb as the other two.

If only, this drought has them so pushed far back in the crap. Haven't seen hide nor hair of one in months. Then again the little ten days I have home a month doesn't leave much time for scouting. that being said I'm curious about some stuff with these bullets . The ones I fired where double quenched and should be pretty hard , not much expansion but honestly for the kinda shot I take on hogs that doesn't really matter too much as long as they go where I want.
That being said I got some that I double coated but let air cool from the oven , so theri basically annealed and should be pretty soft. Things to expand pretty nice but then I need to do a separate load development for those

So took a few out to 100yd today just because, and honestly these shot about who I figured as far as group sized goes though I will say tryin to shoot a 3" sticky with a 4x LPVO who's crosshair covers the whole thing is a lil , annoying laugh
Actually it's pretty close to the steel case SP or HP I used for hog hunting Soo
