I am going to try this for a custom 257ackley i built 2 years ago with a Brux MTU contour 1:8twist i finished at 31" I chsmbered with a reamer i designed to give 0.130" free bore and slightly tight necked just to do a good clean up neck turn on brass. I designed the reamer specifically for using Berger 133gr and 135gr lomg range match bullets and its an absolute hammer. Problem is hardly anyone makes 257rbt +P brass anymore, cant even hardly get 7x57mauser. So i think i will buy Lapua 30-06sprg brass and do this since i use that rifle for unlimited class 1000yd benchrest at Williamsport, PA. My only concern is getting brass flow that will constantly need turned off the outside of the case neck. Which isnt that big of an issue really
Converting cartridge cases is something I do fairly commonly. My top conversions .308 Win to 300 Savage, 7.62x39 to 6.5 Grendel, 40S&W to 357 SIG. It's a dieing art but very necessary for the "odder" cartridges, but it saves alot of money. The .06 is the grandfather of a lot of rounds, a lot! Harbor Freight and Amazon have those mini chop saws, and they work pretty good on the cases. Look up making 300 Blackout from .223 and one of the videos will have them. Get your son to wear safety glasses!
Just make sure you trim your length on those. You can do 270 to 25-06 or neck up to 30-06. People make the mistake though of trying to use 30-06 or 25-06 to make 270win which you shouldnt do since 270win has a neck that is 0.050" longer for max case length and then have a case up in the chamber that the case is short and put all that flame at the back of the throat of their chamber. What you are doing though is fine just trim to 2.485" after otherwise you may have really grity feeling bolt lift after you fire a shot
Yes! Things are going well...nothing exciting! No bass videos lately. Family stuff is more of what I have been focusing on. We're butchering some hogs tomorrow, so maybe I'll shoot some video of that. Hope all is well with you! Dave
I appreciate great dads teaching kids things.
Awesome video
Nice to know!

The 300 BLKOut very popular and available today, no need to go to the 223 cases
It's now a 257 Tenney!
Thanks Chris! It's pig skinning time 😩
Great video. I am wanting to convert .270 Winchester to 25-06 - it should be easy. I am waiting on a 25-06 case gauge on back order.

Greetings Dave. I hope things are good there.
