That's made my ears prick up!
What bullet are you using, and what charge weight?
Cast/swaged bullets are not something I've played with in the 303.

I have a custom Lee 6 cavity mould which is a copy of the RCBS 185gn Silhouette bullet.
It is gas checked and casts at 0.312.
I use the start load of N140 (off hand I think its 38gn but believe I do use 35gn - notes not to hand) which gives me an estimated 2000fps.

Extremely economical and pleasant to shoot.
I sue the same bullet in 303 and 7.5 swiss.

Ideal for use on an ETR range.

Yep I’ve been loading 54r for a little while, 41gr of n140 with 181gr ppu .311 bullets and it shoots lovely

Ive just got myself a load of cases and have cleaned them ready to start loading! Ill probably go for the .311 ppu route

I have just stripped the gun down, sanded the old varnish off all the wood and will re finish it later in the week! Then ill order some bullets

you must size it down some for the Swiss, as mine runs .309 cast, I use unique at the moment but would be interested in your results with N140

my 7.5 Swiss runs on 155gr .311 cast
it was the case length I had trouble with,

shouldnt ever be a problem with case length, ogive size is the classic banana skin, the K31 has no throat as such so you need to adjust bullet seating depth to avoid jamming the bullet into the rifling, the 1889'6 have a throat like a hippo so rarely cause problems.
