I would only size the bullet, before BSing, if it takes to much pressure to seat it w/o sizing.

A .310 base band would be best, tapering to .308/.306 forward of that, as cast.

As a kid growing up in SoCal son of a WWII USN South Pacific vet in a neighborhood where it seemed like everybody came out of the war and instead of going back home bought a cheap home in California, land of milk and honey. Lots of jobs, cheap VA housing, sunshine, beaches and orange trees. My four best friends Fathers moved from Indiana, Ohio, MI the industrial Midwest. All were machinists or tradesmen of similar skills. Like at home they loved to bowl, played 8-Ball or Snooker, lots of weekly card games, smoked cigarettes with no filters and Pabts Blue Ribbon was the only beer.  

Frank Snow was my neighbor and he was starting up Sierra Bullets in a Quonset hut at the time in Whittier, CA. In his shop was a beater Win 94 hanging on the wall. I asked him the story and he claimed it would group 1” or a bit less at 100 yards and would never part with it. There were four or five targets nailed up next to it. Lots of people called BS on him but the story was two of the targets were shot before some of his crew. How and why this old gun could shoot like this boggled the minds of many. I’ve had two old 94’s and one Marlin and 3.5” was best I ever shot. His rifle was a freak.

You had me going for a while there Rick, Didn't think you would ever get to the point.... Grin


I really am terrible that way. I feel sorry for my poor dogs who just have put up with me. That was pretty brief wasn’t it ? I need to work on it

It should be fine if, the bullet comes out concentric. 

Spin it and look at the bands, to see if they are still even, after sizing.


Ordered the NOE mold.  Good timing; Black Friday sale!  Saved 25%.
Got the top punch, too.  Good winter project.
Thanks again,
Mike.

I have a 20” Contender barrel in .30-30

With good quality pointy jacketed bullets it shoots sub 1/2” groups at 200 yds.  I’ve never shot cast bullets with it.  It loves the Sierra 155 grain HPBT Palma bullets.  I was able to get almost 2400 fps with that bullet and both RamShot Tac and BL-C(2) without showing signs of pressure.  I don’t remember the exact loads, but both were right around the max loads in the manuals for 150 grain bullets.


Sub .25 MOA Contender  Smiley

Today I was doing a little bit of load development with an original highwall with a Douglas 1/2 octagon barrel in 30-30.  I have only had this rifle out 3 times but it seems to be easy to make shoot well. 

This is 5 shots @ 100m, a little under an inch center to center.  The rifle has the original straight grip stocks and a 10x Lyman Junior Targetspot.   The load is 31.1gr of H335 and a moly 168gr amax bullet.  I haven't tried cast yet.

Chris.

I have been kind of following this thread with a bit of interest. I have pretty much come to the conclusion that the 30-30 has the potential to be quite the accurate cartridge providing it is used in the proper platform. A good solid action, a quality barrel and good loads it looks like it takes a back seat to no one. Kind of gets me to thinking of building one. I have the dies and a boat load of brass. Might be a very good set up.

Here are a couple of 30 cal rifles I have been trying to get back to working with, "in my spare
time" outside of BPCR.
Browning BPCR rebarreled to Hart  1:8 twist chambered in 32-40 Remington.This cartridge, formed from 303 Brit brass has about the same case capacity as the 30-30. Perhaps shooting comparison could could be done re. the thread regarding 
case forms for accuracy.

Ruger No 1 rebarreled with Obermeyer 5R 1:8.5 twist 
chambered to 30 USA akd 30-40 Krag.

I have a number of bullets to work with as per the photo attached. It is noted my error that the first two bullets on the list
are the 311-242 fn flat base and gas check NOT 311-247

It is noted that the 30 USA is on the left side 
and on the right side are the 32-40 Rem and the 30-30 cases.

You might consider this mold:

(You need to Login or Register to view media files and links).
.

Got the mold and cast up a number of them from some stiff alloy.   

Not going to work.   

The bore riding section (most of the bullet's length) mic's to 0.302"+/- as cast.  Sized a few to 0.309" and that bumped up the BR section even more.
Even my "very used" DCM Garand wouldn't swallow them as cast Undecided

I usually cast with certified 20:1 alloy.  I don't know if that alloy would drop any smaller?  The alloy I used was probably close to WW hardness.

Maybe I'll contact NOE and see what they recommend.

If you are shooting fixed, from the case, don't size the bands, only size the BR nose. Use a .2995 - .300 sizer on the nose. What type of bullet sizer are you using?

If the bands are .311, use a .310 button in the die and give the case mouth and chamfer of at least 1/2 the neck thickness.

If "stiff" is harder than 20/1, it's most likely harder than straight WW. Try 20/1 and see if it cast smaller.

20/1 on a .302 nose may still chamber, if you have narrow lands in the rifling. I only BS and a .302 nose doesn't BS hard but, your nose is a little longer than my BRer bullets.
