After many years I have a new 30-40 Krag.

Lets Get busy making some boolits...

I've dug out my old molds. This one is a 301620. I'm also casting some 311284 and 311467 which I'll use in my initial load development.

Here's the three boolits all loaded up...

Ain't technology wonderful! Here's my iPad loading log with the 30-40 loads.
DON'T TRUST MY LOAD DATA...ALWAYS USE RELIABLE MANUALS!

The proof is in the shooting...http://castboolits.gunloads.com/imagehosting/thum_36454eaf5313bb14f.jpg (http://castboolits.gunloads.com/vbimghost.php?do=displayimg&imgid=2559)
The groups are color-coded. The first 5 shot group is blue. Low with factory sight setting. I moved it up two clicks for the pink group. Both of these are Load #1:
311284 30gr IMR4895, source LASC.
Stats: MEAN FPS 1728, MIN 1704, MAX 1740, STD DEV 10.2, VARIANCE 105.2.
These loads were beam scale loaded for precise load.
The Green is Load # 3B, 311284 21 gr SR4759, source Lyman #4. These boolits were cast with Lyman #2 Alloy. This was my best group.
Stats: MEAN FPS 1742, MIN 1673, MAX 1858, STD DEV 67.5, VARIANCE 4550
The 311467 and 301620 all strung vertically with about 1 MOA horizontal. The velocity of these were about 2050 and 1850 respectively. I've never had great success with paper-patch and the 311467 is a new-to-me mold. These old Guy Loverin designs were considered the best by many. I'll be working more with this and the lighter 311466.
It's interesting that the small group is from the load with the most uniform velocity. I'm not sure if there is a correlation but it is interesting. I've always had good results with SR4559 and am not surprised by these results. I took this from the Lyman 3rd edition Cast Handbook, 'Speaking Frankly' on cast loads for 30-06. Also be sure and read the 'Cast Bullets in the 30-40 Krag' article on LASC (Los Angeles Silhouette Club).
Most of my groups were strung vertically. I'm sure it's my eyes and the open rear sight. I have a Lyman #21 coming from buffaloarms.com. I think this peep sight will help a lot.
Just a little nostalgia..my first rifle was a Model 71 in 348 Win of course. I think it was about 1959 or so. I bought a Lyman Ammunition Maker kit with 310 tool, Lead Pot and 350447 mold. I love Winchesters, old and new.
The 30-40 is a great cast bullet cartridge, and the 1895 is a great gun. Even Teddy R loved it!
