My first custom chamber: 300 Ultra X! (Creedmoor was taken)

[Mram10us]

playing with wildcats is expensive but a lot of fun and more failures then successes. I know I changed my 30-338 rum imp reamer a couple times and about to make another change for all the new bullets and brass that is now available
keep us informed and have fun.

Great to hear from the guys with experience rather than the naysayers. We'd still be using the 30-30 if others stopped experimenting

Here are pics of the primers and sides of case.

Looks like you need to learn how to bush a firing pin hole, holy crap!!

 

[Mram10us]

Never done it. Teach me. Explain

 

[bigngreen]

Youtube it or go to Gretan's website, way easier than me trying to explain anything.

Could those primers relate to a headspace issue?

That's what I like about you...you ain't got a clue what you're doing but doing it anyway...lol
Btw I'm tuning in to learn as well, I always see folks talking about bushing a firing pin, but never bothered to see what that all about.

I like fiddling . That lathe has made more work for me. I've made comparators for my cartridges, headspace making tools, jigs, jags, etc. Crazy what is possible

Today I turned down a punch to knock out the ejector pin cuz I didn't have one that fit. So much easier that running to the store.y

I wouldn't say I don't have a clue. Just never learned how to bush a firing pin always something else to learn

The edges yes but the massive muffin top no.

Not finding anything on YouTube. If you mention a problem, you have to help out. Maybe you could video how you do it. Thanks

Thank you. Lots of speed bumps along the way, but it might work out great .... or maybe not
