Gentlemen,

I have an old Rigby rifle in the caliber 400/350 Rigby Nitro Express.

The rifle is equipped with an ancient scope which does not fit my needs, so I plan to mount an additional modern scope in the old rifle bases for switching from "modern" to "original" condition.

Brass can be obtained from Bell end maybe Horneber.
I used to reform new RWS cases in 9,3x74R.

After forming and thinning of the rim, the cases were fireformed with a medium load of a) Kemira N140 and b) Rottweil R 904 (approx. Reloader 19) with a 250grs Hornady SPRN bullet.

If you are interested, I can provide more data.
Up to now I did shoot the rifle only on the range, for hunting I would stay with the Hornady 250grs SPRN or the Woodleigh 250grs SPRN.
Feeding of the 250grs Partition was not successful, the lead points tend to be deformed.
The system is a Mauser 98 Magnum system, which has a more shallow angle of cartridge to chamber axis, but the rifle dislikes feeding Partitions.

With round nose bullets the rifle feeds flawlessly, even with the Woodleigh 310grs SPRN.

best regards
Rolf
