Gunsmithing Please help me understand chamber dimensions...

[DoSqH]

And how they will affect or help guide me in loading for a particular rifle....

Was directed to re-ask my question from the 'Reloading Forum' over here for more context...

Not all of them...but in particular the neck and freebore.

The rifle I just picked up was chambered with a 223 Remington Match chamber reamer. I was told that the neck dimension is .253" and that is has 0 freebore.

Typically when loading for my Service Rifle I've always used LC brass, unturned necks, and a Redding S die with a .245 bushing. All of the barrels were White Oaks and chambered with a 223 Wylde reamer.

So in this new Remington Match chamber it's my understanding that the throat is right there at the end of the case mouth...and the lands right there too. So seating to touching the lands will have to be measure for each of my bullets vs. previous loads. From a neck tension standpoint would I benefit from turning my necks and finding a new bushing size to better suit this chamber?

I feel like I'm missing something here and looking for a little guidance on where to learn from.

Thanks!

Jake

Your question was already answered by spiife and very well. Hoping Lynn Jr. Doesn't see this one or the other. But if you run across him pay no mind. Shelled shock during the Battle of Santa Clara in his own mind.
