Re: 303 happiness
It’s not a headspace issue. The 303 head spaces on the rim, it’s just a chamber designed to function in adverse conditions and not worry about reloading brass.
Don’t take life too seriously, no one gets out alive.

Re: 303 happiness
Not quite. The chamber is oversize and yes the headspace is slightly more than hunting rifles on regular Lee-Enfields, but brass does last quite a while even when full-length resizing.
What we are talking about is excessive headspace that you get with some 303's. By that I mean either the action made slightly longer than standard, bolts made slightly shorter than standard, non-original bolt, or from DIY gunsmithing "improving" the locking lugs.

Re: 303 happiness
The round nose Hornady 174 gr bullet almost seems to be a cure all problems bullet. I just works, longer bearing surface. I have .303 thread here some where (2 I think) relating my trip from A5 to touching hole groups.

Interesting that I also load 38.5gr S335 behind a 174grain bullet. Have hit a 30x30 military plate out to 600 yards with it.

Re: 303 happiness
Where did you get that load data Against the grain ? 44 gr S341 is 2 gr above the maximum load as per Somchem. Although they use a 180 gr bullet, the 6 gr difference has little infleunce in this regard.

Re: 303 happiness
Jokes aside, 600 yards is just less that half the total elevation on the peep sight which is calibrated up to (an extremely optimistic) 1300 yards.
