It’s a protein, it can be eliminated way more easily than you are suggesting. It does however linger on surfaces for a long time if it’s not cleaned properly. Usually in the lab we use a light acid to denature/ destroy the protein.

Maybe check out the 6.5 Sherman short?

This Wilson expanding mandrel works really well for expanding the cases. I go straight to 33 cal from 270 with zero problems. I just jam the bullet into the throat and fireform

My ar15 grendel has a very soft recoil. Any kid should be able to handle it.

Thank you

I only fireformed cases, my scope bit the dust and didn’t move forward with the project. Just picked another up so sometime in the next few months I will be working up loads. The leupold scope I bought was only 2 feet high at 100, it tracks backwards vertically and will go no lower

270 win brass

I only have 1 shot through my Winchester brass. I’m afraid I can’t help much there. The leupold scope I have on my gun tracks backwards up and down and the lowest I can get it is 8” high at 100. My experimentation ended early this year due to that. I say load 10-15 of each up and find out.

I have only used 230 grain Hornady copper bullets. I am using Winchester brass with no issues. I don’t think I had to trim at all with 270w brass (I’m not near my bench or notes atm). Of course I did fireform the case so there’s that. The issue with win brass is that it is softer than the...

The non e The non expanded brass chambers just fine FYI

It’s the neck diameter. My readings say .368-.369 And the sharpie is scraped off most of the way down the neck on a piece I trimmed way back. That confirms it in my mind. Unfortunately I don’t have a way to turn them right now. On to the 270 brass. The length is 2.5 with the neck expanded if...

I’ll breakout the marker to check

I’m just starting on fire forming loads and noticed that the Peterson 280ai brass will not chamber. I thought the brass would need to stretch not be set back. Does that seem right? The 270 win brass I have chambers with no issues when necked up.

Ahh perfect, I was think heavy 06 but that makes more sense. Thanks again
