Furyan Posted October 30, 2016 Report Share Posted October 30, 2016 Hi has anyone tried 30gr Berger`s in their .17 Hornet , Mine like most other CZ i think are 1 in 9 twist 24" barrel. Thank you. Link to comment Share on other sites More sharing options...
srvet Posted October 30, 2016 Report Share Posted October 30, 2016 Are they not a bit heavy and would a 20g or 25g bullet not be easier to stabilise? Link to comment Share on other sites More sharing options...
Furyan Posted October 31, 2016 Author Report Share Posted October 31, 2016 Not sure just wondering if they would be any good in 1-9 Link to comment Share on other sites More sharing options...
gbal Posted October 31, 2016 Report Share Posted October 31, 2016 Berger's "Twist rate stability calculator" will be a good guide,backed by the laws of physics and considerable expertise ion this very topic.Might even agree with "my buddy shoots them,ok"/"tried them and didn't work" which some seem to put more weight on. There will be some ballistic price to pay,but maybe an energy trade off....but stability is all.My experience with the much larger capacity 17Rem showed no advantage in 30g,and disintegration with 15-18g,with 25g about perfect for the cartridge.Most end up there too. The 17H will be at it's cartridge best with a lighter bullet in the much smaller case,probably the factory bullet weight. gbal Link to comment Share on other sites More sharing options...
Furyan Posted October 31, 2016 Author Report Share Posted October 31, 2016 Many thanks for that Gbal, think ill stick with 25s and try to find some 25 HP . Link to comment Share on other sites More sharing options...
gbal Posted October 31, 2016 Report Share Posted October 31, 2016 We all can be tempted to the better mousetrap idea....and just sometimes there is a niche application advantage-a tad more energy eg (though really if marginal,a different cartridge should be used).... ...the Bergers might just offer improved accuracy in some rifles too...though maybe not/and is it critical? The initial velocity attraction eg of the 15.5 g lead free 17Hornet load is soon haemorrhaged away,just as with say 224 Varmint Grenades in a 222,devastating though these uber velocity and frangible bullets can be at limited range, 'uber dead' offers little advantage over 'dead' (corvids possibly excepted) and for fox, the wrong bullet). There should be 25 and 20 g ammo available in 17Hornet (20g@3650fps sounds rather impressive,used at sensible ranges)! g Link to comment Share on other sites More sharing options...
