43 Mauser and SR-4759 and Dacron?

[Fox]

Found almost a pound of SR-4759 and figured why not use it up in the 43 Mauser.

I have found data with this for trapdoor 45-70 but it showed Dacron filler is necessary. The 4198 loads for 43 Mauser line up with the 45-70 trapdoor loads but although the 45-70 data says to use Dacron the same cannot be said for the 43 Mauser published data.

Is Dacron necessary? Is it a bad idea?

Don’t you mean SR 4759?

Stuff it with 1/2 sheet toilet paper (unused).

Found almost a pound of SR-4579 and

lucky bugger!!!

I used up a couple tube of 4759 in 45-70, tried some with dacron and couldnt see an improvement over no dacron but i did see an improvement in consistency in my 45-90 so in a bigger case it was worthwhile.

I’ve used 4759 in a lot of things including 45/70 a d .458 Lott and never used dacron or anything else. I always thought that that was the point of 4759, light charge weights, low to mid-range loads and bulky as hell to take up some of the space. Back in the square tin days it came in 1/2 pounders.
Last time I bought any it was in 12 pound mini beer meg looking things for 150 a keg. Not that it has anything to do with anything, but I like saying it. Yeah, I got lots

It is funny that you say that, yes this is an old metal tin.

I went to weigh some 700x I have from back in the day, just to plan out some 16ga loads and decided to weigh everything. Looks like I have 6.1oz of 4759, ha ha.

I load 4759 in my 45-70 and tried it with and without a filler. With the filler, the velocity was 100fps higher but the extreme spread went to over a 100 fps difference.
