Bullseye 30-40 Krag Loads needed

[brstevns]

Looking for some 30-40 Krag loads using Bullsye powder and bullets from 130 gr. to 220 gr. Have a 311359 , 311291 and 311284 molds to try as well as the Lee 155gr made for the SKS
These would be shot from a Siamese 98 Action rifle.

I work in the range of 5 to 7 grains in the .303 Brit and .30-40, and up to 9 grains in the .30-'06, in your Siamese Mauser you should find a sweet spot with 211284 or 311299 from 7-8 grains.

Not going to happen powder way to fast. Unique will work. 5744 is a great powder for that round. I just looked at 160 loads and none were bullseye. Good luck be careful

Of course it will work. It's Bullseye.
I envy your Siamese 30-40. I built one in the shop at high school in 1976 (in letting & sanding a Bishop stock). A gunsmith fitted a McGowan barrel and it was a dandy. With that action I ran it up to max .308 levels with no problems. It's still getting game down in Eagle Pass, Texas with a friend's family.
Best, Thomas.

Lyman has always been an advocate of pistol powders for reduced cast bullet loads in rifle cartridges. While it will probably work, there are more suitable powders than Bullseye. Lyman doesn't recommend it in their data for the .30-40 or other comparatively large cases, perhaps for good reason.

Looking for Bullseye loads because I was gifted, almost 2 lb. Just some loads giving around 1400 fps would be great.

Bullseye isn't going to give you 1400 fps before going over-pressure and leading. The most satisfactory small game and gallery loads using it in rifles will be in the range of 900-1300 fps, being well suited for soft, plainbased bullets. In the .30-40 you can expect good results with charges from 5-7 grains, but once cast bullet velocity goes supersonic pressure can spike quickly with small increases in powder charge. If velocity is more important to you than accuracy and clean shooting, without leading, you should select a different powder.

Essential for understanding the proper application of Bullseye in reduced rifle loads is that it is a low velocity powder for light charges only. It tolerates free airspace in the case well and is easily ignited so that no fillers are needed. A correct charge of Bullseye must also be light enough that an inadvertent double-charge will not blow up the gun!

Just a FYI comment:
According to Quickload, a 311291 boolit fired in a 24" barrel needs 9.0grns of Bullseye to reach 1417fps. It does so producing 17,774psi pressure. Considering the 30-40's max pressure is 47,000psi, it seems quite "do-able" with Bullseye in my eyes. Not the optimum powder to use for this application, but useable.

MAP is the sample average plus three standard deviations. 47kpsi is NOT a safe loading limit for .30-40!

A handy chart that I have printed out and stuck in my reloading binder.

Personally, I don't load my 30-40 to anywhere near max, but 40K-47K is considered max for this cartridge.

I could live with 1300 fps with the 311284 lyman bullet !

Ok, read this:

BULLSEYE most certainly will work. Pay particular attention to post numbers 6 and 19.

I have a Siamese Mauser and not a Krag rifle, so I would think this would me a safe load in it. I would never use this load in a Krag or a Old RB rifle.

At 3.2 grs of Bullseye, you will not be anywhere near max pressure for the .30-40. You did read the thread I linked above, correct? Bullseye is for mouse fart loads only.

[brstevns]

Yes I Did, very interesting.

6 grs should work just fine for 220 gr on down.
I used 6.8 grs/200gr RCBS in my .358 with no problems.

I will give it a try.
