I know there has previously been a similar question asked, but that thread is of some antiquity now so I thought it worth a go.

Looking for data for the .350 Magnum Rigby using 225 Partitions, Bertram brass and either Fed 215 or 210 GM primers, in UK so powders such as IMR or H 4831 H 4350 no longer imported thanks to European safety regulations (REACH Regs). Was hoping to use one of Rel 15: 19 or maybe 22 which we can still obtain, albeit with some supply issues.

Rifle is an original single square bridge .350 which we are hoping to get back into regular use notwithstanding some issues sourcing readily available factory ammo, only Kynamco load this in the UK but have zero stocks and no suggestion that position is likely to change anytime soon.

Any help or insight greatly appreciated.

Many thanks

Jonathan

Reloder 15 would work for 200 grain bullets. For the 250's I would go with a slower powder.

For the 250 Partition, Nosler used to recommend the following Max loads:

Removed, 350 Rigby Magnum data

Thank you both.

Frank. May I just check we are on the same cartridge here. 100 plus grains seems considerable

The loads I have so far is from the Woodleigh Loading Manual and covers H4350 or H4831 nether imported into the UK any longer ( although I have managed to source one canister so far) but the range given appears from 70- 76 grains H 4831 SC, the latter lying right up to the base of the bullet, I do wonder if I could even get to 80 grains of 4831 without considerable compression?

Many thanks

Jonathan, My apologies. I had 350 Rigby Magnum data. I removed it.

Frank

No worries, thank you for clarifying.
