Birx Posted July 31, 2011 Report Share Posted July 31, 2011 I've been using Hornady 17 grain V-max in my CZ, and achieving sub 1inch groups at 110yds. I recently bought some Winchester Supreme 17 grain V-Max because the shop didn't have any Hornadys. Five shot groups with these were rarely sub 4inch. I was astonished at the difference (especially as I'd stupidly bought 250 of them) Has anyone else experienced such extreme group sizes with different HMR ammo?

triscrx Posted July 31, 2011 Report Share Posted July 31, 2011 I used to buy the Remington but my local RFD hasn't had any in for a long time so I have switched to Hornady and find them very good. Cheaper too in my shop Quote Link to comment Share on other sites More sharing options...

I thought they made them all? Do Winchester make their own? Quote Link to comment Share on other sites More sharing options...
Salop Matt Posted August 1, 2011 Report Share Posted August 1, 2011 My CZ452 american heavy barrel likes its diet of Hornaday 17grn`s I did once try some other ammo and my rifle didnt mind the change at all. As ive always been able to buy hornaday thats all ive ever used in my 2.5 years of ownership ! Quote Link to comment Share on other sites More sharing options...
kyska Posted August 1, 2011 Report Share Posted August 1, 2011 I've always used remington, my first hmr just wouldn't produce a tight pattern with hornady, all the rest I've had have got on with rem's so have stuck with them. Quote Link to comment Share on other sites More sharing options...

Gimlet Posted August 1, 2011 Report Share Posted August 1, 2011 (edited) I've been using Hornady 17 grain V-max in my CZ, and achieving sub 1inch groups at 110yds. I recently bought some Winchester Supreme 17 grain V-Max because the shop didn't have any Hornadys. Five shot groups with these were rarely sub 4inch. I was astonished at the difference (especially as I'd stupidly bought 250 of them) Has anyone else experienced such extreme group sizes with different HMR ammo? Take any unopened winchesters back. I've done that with ammo the rifle didn't like and they swapped them like for like. My HW60 is the opposite of your CZ. It tack drives Winchesters, tolerates Hornadys below 100 yds but throws them around all over the place at 120+. Its all down to your rifle's harmonics. No two are exactly the same and you just have to find the ammo that suits the individual resonance of your gun. It varies between models of the same make too. Most HW owners report that their rifles love Remmingtons. Mine treats them like plum stones. Its Winchesters for me or take a catapult. If a gun is that fussy it pays to buy your maximum allocation from the same batch of your favourite ammo if you can.
