This one should throw the cat amongst the pigeons... I used to be a strong advocate of Spirit of the Original, with Full Service Loads and all of that. As all good, right-thinking people were. However, I have changed my tune significantly in the last few years, for several reasons: 1. Cost of components -- this has gone through the roof in the last few years, and availability (particularly of 311-diameter bullets) can be patchy. 70 pounds for a kilo of powder that will load around 300 rounds? You're having a laugh. Add onto that over 10 pounds per hundred for S&B or Privi FMJ's, or almost 30 pounds per hundred for something decent like Sierra match kings, 25-30 pounds per thousand for primers and you already looking at pushing 40 pence a round for blatting ammo, or over 50 pence per round for match. 2. Cost of replacement barrels/new rifles -- again, through the roof. Arm-and-a-leg Sarony will do you a new barrel for a number 4 for about 350 pounds! So not wanting to wear out a barrel with full house loads is certainly a valid argument. 3. My personal circumstances -- I have weekly access to a 100 m range and almost never have access to longer. 4. Cast bullet accuracy -- is actually not an awful lot better out of old military rifles than FMJ, yet costs an absolute fraction of what FMJ costs. So, I now have no complaints whatsoever about people shooting cast bullets, even ones tailored to different distances -- they are really only protecting their barrels and their shoulders without any competitive advantage (let's not forget that slow, cast loads get blown around far more than 180gn MK's @ 2400fps). I know some of you have strong opinions on this, so flame on!
