Developing/Choosing a Hunting Bullet for a Win 30-30
My wife gave me a Winchester 94AE for Christmas (apparently I'd been better than I thought), and now I'm working up a hunting load for whitetail deer. My son gave me some NOE Ranch Dog 165gr but they are too large to feed reliably. I have to seat them deeply otherwise they heavily engrave and take a hard lever squeeze to chamber. At that point they are too short to feed reliably. This isn't a knock on the RD bullet, it and my rifle's chamber just aren't a match.
I upset a slug in the chamber and took the following measurements:
(Brass trimmed to 2.020 Measured from outside of rim.)
Outside of rim to start of throat taper = 2.090
End of brass to start of throat taper = .070 (would be .050 if I trim to 2.039 max length)
Length of throat = .050
Barrel slugs at .3085x.301
I'd like to be able to buy a cheap Lee 2 cavity, but reading Ranch Dog's posts about bullet design has me convinced that I need to look into getting a custom mold. I can get a single cavity cut to my specs from Accurate for about $80. I'll need a gas check and would like a tumble lube design. Any ideas? Obviously I'd like to get Ranch Dog's input on this. Thanks!

Re: Developing/Choosing a Hunting Bullet for a Win 30-30
Has this case been fired in this rifle?
It looks to me like you have a very short amount of freebore followed by a short amount of step, the sum of the two being your throat.
The dimensions of "A", "B", and "C" are important. Also take a dimension about a .25" north of "A" to see if there is a leade.

Re: Developing/Choosing a Hunting Bullet for a Win 30-30
Thanks for your help.
Just to be sure my measurements are good, I made another cast. I resized a piece of brass, loaded a stiff jacketed load, fired it, cleaned the bore, and used a nice clean pure lead bullet.
I then measured everything about 10 times.
Dimension A = .3085
Dimension B = .330
Dimension C = .331
1/4" north of A =.3085
The distance from Diameter B to Diameter A is .040 as near as I could eyeball it with my calipers.

Thanks, give me up to a couple of days and I will see what I can do.

I don't think I've ever had a similar problem with my old 94.
I've since acquired a mystery metal 94 and a 94 AE that I've not even tried lead in yet.
I look forward to following some interesting discussion.

It is said that a picture is worth a thousand words so let's give it a try!

Your chamber with a bullet that fits!

Here it is, the Ranch Dog TLC310-170-RF KiLR (took a bit of liberty with your initials!)

Spent way too much time on this today, about 7 hours... got to go do some wiring on my truck now.

Re: Developing/Choosing a Hunting Bullet for a Win 30-30
Wow! That looks great. I really, really appreciate it. If I would have known it was that much time I wouldn't have imposed.
Now I need to send this to Accurate Molds and see if he can cut it. I don't think NOE does a one-off.
Thanks!

I will get you a detail drawing, this one isn't sufficient to make the tooling.

Re: Developing/Choosing a Hunting Bullet for a Win 30-30
Thanks. Take all the time you need.
BTW, I'm not trying to look a gift horse in the mouth, but do you mind if I double check a few of the measurements? I took two sets of measurements and I feel the second impact cast was the most accurate and taken with an average case length rather than the minimum case length I originally trimmed to. Also, the body diameter is shown as .303. Should that be .310?
Thanks.
