Great info guys , so the SMLE action has been done in 7.62x54R , that would be quite neat to , I thought that it was a high pressure round ?

Interesting on the use of 303 in old Drillings after the war , may have worked better in some I suppose .

Thank you for the pressure info , I just could not find it , so it sounds like it would be good to go & a good round I think it is to !
