An old favorite

[Ben]

For the many who feel the gas check needs to stay in the neck of the case, the 30-30 Win. and the 30-40 Krag are all time favorites.

Here is my " new to me " NOE 30 Hunter, sized .310", seated to chamber smoothly in my T/C Contender , Super 14, 30-30 Win.

In this particular situation, the cast bullet has all the lube rings in the case neck but the gas check IS NOT below the neck.

Tis for sure Ben, a fine looking ctg!

And here I was thinking I was the only one with severe enough OCD to neck-turn the .30 WCF, seems the cat is out of the bag now.....

I only set the cutter close enough to cut 1/2 to 2/3 of the way around so's to only remove most of the high side, and it do make a difference at long range. I like to draw them after turning and fireform once or twice with tape or an o-ring back by the rim before doing things like comparing lubes etc for grouping. Then I have that shoebox full of "shoot 'em 'till they split" mixed range stuff, unknowns, and extras which get loaded up with a Lee round nose bullet and used up on the periodic migrating herds of hostile, rabid Dr. Pepper cans and empty gear oil bottles.

Geez Ben, Your kinda making me wish I'd bought that one too.
Can't wait to hear more results.

I can't chamber anything larger than .308 in my 10" 30-30 barrel without turning necks......

Mine are all turned to .010 "

Those T/C's are known for VERY tight chambers.
I had to have a gunsmith in CO cut a complete new chamber in my Super 14, 30-30 barrel. It came with zero throat.

I've read that T/C chambers had quality control issues.
Some are fantastic, some need quite a bit of work before a cast bullet shooter can use the barrel.

usually they cut a throat in their barrels that goes to about 1/4" from the muzzle.

Oh, like some of the Marlins. Actually, I think Marlin for about thirty years there was using the same reamer with the end broken off where there's supposed to be a step at the end of the chamber, so they just made up the difference with a bigger MicroGroove button swage and pulled the leade clear through the barrel. Then I bought a later model JM from Josh and it's throated like a Winchester or Chicopee Falls Savage.

Having a too-tight neck and throat is a good thing, because you can fix it. If it's the other way around, you're basically screwed.
