Loading 110 gr 308 carbine in 30-30

[Hank Zudd]

got some 110 gr soft point jacketed (lead round nose) sierras that I'm gonna load in a 30-30; Bag sez they're for 30 carbine, but they're still .308.

I know about keeping the max. OAL, but is there a minimum OAL when feeding em' in a Marlin 336?

The powder charge should be the same for this 110 gr. as any other 110 gr.? thanks

OAL, minimum

Press a bullet to minimum depth into an unprimed not-loaded cartridge, measure the OAL, and then chamber it slowly. Recheck the OAL after extraction. Then check several loading manuals for recommended head-space and load for your Marlin336. The "jump" from case to rifling is important for accuracy and safety. Don't be tempted to try filling up the cartridge just because there may be more room. Check your loads with a chronometer, and don't go nuts. You have a good combination in your hands. Good luck.

that's pretty much what I did with my 222 in a Savaage 340 today; just wanted to know if anyone had some starting numbers.

thanks

"starting" numbers.

It's pretty much a poor idea for anyone to post weights, etc. on-line as a suggestion for others to use. I'd keep such data in my mind, but I'd begin at the lower end, and chrony my loads with explicit figures until I reached a safe plateau for MY OWN PARTICULAR gun. I recently found a set of .44 mag dies, and the data the previous user had kept came along with them. Very expensive for me to repeat all of that trial and error, but I kept it in mind as I built my own packages. I have a Desert Eagle in .44 mag with 6 inch, 10 inch, and 14 inch barrels. The data in my dies is for a carbine barrel of 16 inches. But it's a place to start. Good luck in your experimenting. And, by the way, you can get oooodles of numbers by just Googling your caliber/bullet wt combination. Study them carefully. Your 110 gr. bullet is quite light, and it won't take a whole lot of powder to get going REAL fast and flat.

Here's a site with some data for 110gr. Use with caution, and start 10% below any max load.

Every loading manual in my house lists loads for the 110 grain .30 carbine bullet in the 30-30.

Be aware that ammo for use in a tube magazine needs to be crimped to keep recoil & mag spring tension from driving the bullets back in the cases.

But .30 Carbine bullets do not have a crimp cannelure.

One option is to pick a powder that completely fills the case so there is no room for bullet set-back to occur.

WW-748 will give you a compressed load, while still well below max pressure.

i'm using a Lee crimp die; it sez you can crimp boolits w/o a cannelure.
thanks for all the imput.
