I recently bought a 1942 Lithgow No1 MkIII* to shoot service rifle here in Australia. Since that means using the original open sights the desire is to duplicate as closely as possible the military load in charge and especially in bullet weight and shape. As it happens Sierra makes the 174gn MatchKing HPBT which is scary accurate with a BC of almost .500, particularly good because it's precisely the same weight as the 303 British MkVII ammunition and the right shape too. That's fine for punching holes in a man sized target at up to 300yds.
However, what really stumps me is why there aren't .303 cal 174gn hunting bullets that are even close to the ballistic efficiency of the MatchKing. Admittedly Sierra makes the 180gn SPT Pro-Hunter which has a BC of around .400 but you have to ask why they aren't making a 174gn SPBT GameKing which would have to be close behind the MatchKing in BC.
And don't get me wrong there are some 174gn hunting bullets out there. Woodleigh, the Aussie bonded core maker, produce a 174gn Protected Point (like a Mag Tip) which has a BC of .362, but that's not even as high as the 180gn Sierra. And the .303 cal 174gn RN Norma loads into their 7.7 Japanese and 7.65 Argentine has a really low BC of .262. And that's not even mentioning the 180gn RNs from Remington and Speer. I also don't think it bears mentioning the Hornady offerings since they've suspended manufacture of them.
Any theories on why 174gn SPs are mostly RNs?
