30 TC case dimensions


Registered Users do not see the above ad.


Gents,
I could use a little help with the 30 TC. A friend has asked me to reload this new caliber for him. He has spent brass, and all I will need is his rifle, the dies, a shellholder and a couple of unfired rounds for baseline measurements. The dies are easy to get, but there is no specific shell holders for 30 TC listed.

I am sure the .308 shell holder will work but would appreciate a confirmation of that from any of the members. It will be several weeks before I see him again to obtain any cases for measurement and would like to have everything I need in advance. It seems to be a neat little cartridge. Thanks, Salt

I don't have a drawing of it, but the February Guns and Ammo has an article on line that says, in part:

So, yes, it's the same good old #3 RCBS shell holder or #2 in Lyman or Lee, or #1 in Hornady, Redding, and C-H.

The dimensions are the same as the .308 Winchester, given normal tolerances.

This is a pretty poor picture but I hope it illustrates how difficult it is to keep these cartridges separated in a cartridge collection.
There is not a great deal of difference between these cartridges.

This power class of cartridges interests me most for deer, pigs and even larger game. When I started hunting in the late 1950ís and early 1960ís the 300 Savage was commonly used for Elk hunting in New Mexico.
This power class includes the 307 Winchester and the 30-40 Krag.
Due to a variety of accidents I have limited upper body strength and a right wrist with limited flexibility and strength. This class of rifle tends to be a bit lighter which helps me support the rifles forend when shooting offhand. I consider the recoil from these cartridges to be light and I shoot them well.
The case capacity and pressure limits established for these cartridges allows the handloader a wide selection of component powders and bullet weights. Using todayís premium bullets and some of the newer powders you will have no difficulty tailoring your handloads over a wide range of power levels. It will take many years of shooting to fully explore the capabilities of any of these cartridges. I look forward to reading your range results.

Slim,
The Hornady factory 30 TC ammo states 2940 f.p.s. with 150 gr. Just a little better than .06 if 2910 is the standard. I doubt I will be able to acheive that with over the counter powders for my friend, but at least he understands that the game will not know the difference between 2800 and 2940 f.p.s. He will primarily be hunting whitetails and an occasional hog. I'm sure though, I can build him some accurate ammo at a savings and that is our real goal. I will let you know the results. Salt
