@csmiffy I have 303-25 dies but no 303-25 rifle

I brought them to help form 303-22 Brass for a rifle that was offered to me

The offer is hanging out there but the vendors expectations are unrealistic
Massive case, slow twist barrel. Means ultra fast speeds and ####ed bore

Simplex do dies not too pricey

Data for the 303/.25 is sorted by action type. Rear locker/SMLE and P14 / front locker.

Velocities for front lockers is similar to .25 savage. 87 at 3000 fps, 100s at 2800-2950 fps.

Powders in the 2206h, W748 to 2208, 2209, W760 burn rate range.

Rifles are about over here but demand is low. I’d rather a .25 sav on a kurz Mauser than a 303/.25 on a SMLE if I was going to get all nostalgic.

Surely a 257 Robert's would be a better match for a mauser

A "Kurz" Mauser is a short action (only produced as sporting rifles by the Oberndorf factory), originally chambered in 250 Savage etc

Makka, I have a Robert’s on the std Mauser. Years ago when working on a property in western QLD and old bloke turned up with and original kurz mouser in .250/3000.
It was a slick piece. The memory remains.

I have had an itch to build a 25 souper have the dies but never got round to it . This new 25 creedmoore does seem to be just a modern version of an older wildcat souper . Might be an easier way to scratch an itch though.

The Souper will have a few more fps

I have a 25 Souper built on a 24-inch barrel Tikka M55, normally shooting 100gn (87gn for long range wallabies). It replaced a 25-06 which wasn't much faster for more powder burnt.
