I've been planning to load up some 65g vmax rounds for foxing and thought that I may try to load some with a bit less 'oomph' and so reduce recoil. I don't think that I need the extra 600fps or uberflat trajectory, given that most of my foxing is over the small fields of Devon where a 100m shot is long range. I've currently got some N160, and usually load 100g softpoints. The min load for N160 given in the Lee Manual (for a 70g bullet) is 49.1g compressed, whereas the min load for a 100g bullet is 34.4g. I read that the danger of down loading is that of flashover, if insufficient case space is used, with the suggestion that 80% of case be filled to avoid this. My calculation is that for a .243 case of 3.4cc, 80% is ~2.75, making a minimum load in N160 of 37.5g
Can anyone suggest any problems that I may encounter if I use this lower 'minimum load' of 37.5g as opposed to the Lee recommendation of 49.1g. I usually stay well within the recommendations, so this is (may be) my first foray into more exploratory reloading
