I have an elderly No4 Mk1 which is normally only shot at 100y so I am going to try to find a lightish load for the old girl. (It will be beneficial to both of us) I've got some 150gn SPMJ PPU bullets and as I use N140 for three rifles am looking to keep it simple and use this rather than a different powder. I was planning to use around 22gn as a starting load but if anyone has tried this with success I would be grateful for any info.
