This may be a tough one!

[fourarmed]

Here's the problem: 10" pistol barrel chambered in .30-30. Boolit is the RG-4 SAECO at 200 gr. I can't find any published .30-30 data for boolits this heavy. I consulted the tea leaves and loaded 15/2400, 15/4759, and 19/Re-7. If any of these spur an "EEEK" from the cognoscenti, I would like to hear it. Any other suggestions?

..............I had read an article quite sometime back, and in fact I believe it was one of those "Readers Write" articles about really heavy for caliber cast boolit in the 30-30. IIRC they used 4350. Rather then use that powder I used surplus WC872 under a Lyman 311284 @ 215grs.

OAL was too long to feed from the magazine so it was a single load proposition. Velocity was about 1600 fps and accuracy was very good. This was in a really good conditon old 1893 Marlin that had belonged to my great grandfather. It was one of those rifles that did very well with most anything you fed it.

I can't comment on those powder charges other then I'm sure they'd be okay. I used a lot of 4198 (similar to Re7) in that 30-30 at 21.0grs and a 160 Lee and it was a mild load.

In my 336 30-30 using 22 BHN 170 grain GC Lee bullets, the groups start to open up with 18.5 grains of 4759 or 4227. 18 grains is a very accurate load. 19 grains gives slight pressure signs in my near-new 336, and I certainly wouldn't recommend that pressure level.

Sounds to me as if 15/4759 with a well-fitted 200 grain bullet in an action at least as strong as a Marlin 336, should be a safe place to start, for what my opinion is worth. I have no experience with 2400 or Re7. I doubt either is sold in Australia. However Re7 is just a tad slower than 4227, so I think the 19 grains you've suggested would be a considerably higher pressure load than 15 grains of 4759. Being conservative, I'd start a bit lower to be on the safe side, just because I don't have experience with 200 grain bullets in the 30-30.

FA;
I load for a .303 Savage, balistically the same as a .30-30.
With a 200gr RN GC, I use 34gr BLC-2, gives 1970fps and 24gr IMR 4198, also gives 1970fps.
These are my factory duplication loads for my rifle.
30gr BLC-2 gave 1750fps, still a very useable hunting load.

The new Lyman48 th. shows a 173 grain as largest. I like RX-7. Starting load with 173 grain is 20.0 at 1486 fps, and max of 28.6 grains at 2088 fps. I would extrapolate and start 18.0 grains of RX 7, Tom.:castmine:

I have Quickload if you want to PM me, I will tell you what info is needed.

16.0 grains of 2400 with a 200 grain bullet is a standard target load for the .30.06 (with a 24 inch barrel).

15 grains in a 10 inch .30/30 doesn't sound all that bad. Watch for muzzle flash and you may have to try some faster powders.

I shot the first test loads with the RG-4/.30-30 combo. They showed that my initial loads were (thankfully) conservative. Statistics are: (# shots, avg. v, ext. spr.). For 15gr./4759 I got (12, 1280, 90) and 2.5" at 70 yards. 15/2400 gave (10,1390, 96) and 3.5". 19/Re-7 yielded (10,1220,228) and 6" group. All holes showed that the bullets were tipped going through the target.

The nose of this bullet is a tight fit in the throat, and I can't be sure that I didn't push some of them back into the case chambering them. I know that happened with one of the 4759 loads. It showed 600 fps, and was deleted from the data. The driving bands mike .309", and I sized and checked in a .310 die, so the neck was not as tight on the bullets as it should be for the circumstances. I will have to get a .309 die to go farther.
