.348 Win reduced loads using SR4759?

[Bwana John]

Hi,
Id like to make up some reduced loads for a buddy's .348 Winchester.
Does anybody have any data for that caliber and powder?
I found data for SR 4759 with 35 Whelen and 35 Rem Mag, both are very similar in caliber and powder capacity, but very different is case shape.

When I get home I can check my older Speer manual and see if it has .348 Win.

Try Trail Boss

A couple months ago, Handloader mag. had an article on using Trail Boss for these reduced loads.

Basically, the process is to calculate the under-bullet volume of the case and start with 70-75% of that volume in TB.

Big caution is to never compress Trail Boss.

Trail boss would be the way to go with reduced loads in most rifles.

I have a 348 but haven't run any lower loads in it but I use TB in lots of handgun calibers (32-20, 38/357, 45LC/Schof, and 44 mag). pretty much as posted above, stay away from compression of the powder and you're good to go. check the OAL of a seated bullet/brass combo and compare it to the OAL of the bullet and work from that.
