They are a military weapon and destined never to be a tack driver good enough for a regular trained soldier to hit the COM of a person at reasonable ranges I'm not going to quote any distances as they all had different levels of skill.
Plus the rifles though close some may have been more accurate than others but the data I sent you from what I ended up using with all my 303's should give you good results if you want do a ladder test and see which weight of charge gives the best grouping.
There is plenty of info on how to conduct a ladder test, try the Hornady 140Gn SPFB .312" they do work the SMK's work very well also I also used the Highland 174Gn which also worked very well I think S&B own them now.
Seat them with a medium crimp as my above pic shows, check mag fit and also chambering, I did up a dummy round for this but it will work if done like I did it same charge weight.
I also have @400 Taipan 170Gn HPFB .312" but these are very special and I doubt I'll ever use them as the Australian company TAIPAN Bullets after many years producing outstanding projectiles the owner getting to old stopped production.
Another chap started the company back up with the original tooling but break in's, theft's and damage to machines saw the company fold for good so bl**dy sad it was because they were outstanding projectiles any Aussie who used the 303 projies will attest, I won allot of matches with them.
