Hi
I've just bought a Heym rifle in 7x57. All the reloading data on the powder manufacturers websites shows slower speeds than for a 7-08. Heym factory test their rifles to 110,000psi so I know the rifle has a strong action.The 7x57 is the parent case for the 6mm Remington which has equally high pressures as the 7-08.Thus with the higher case capacity of the 7x57, I see no reason why I should not be able to get speeds at least equal to the 7-08.I'm not trying to make my 7x57 into a 7mm rem mag I just want it to equal or best the 7-08. I understand that with lots of old military actions around , for legal reasons hotter loads cannot be published. Therefore I am not asking for recommendations , I just want to know what other people are loading in their 7x57s and what speeds they are getting .I only own 1 gun and thus I am targeting 3100fps+ with 120gr nosler BTs for foxes and Roe deer , 2900fps+ with 140gr nosler BTs for Red deer and 2700fps+ 160gr nosler partition for Wild boar and moose. Anyone doing these or something similar in their 7x57s?
many thanks Steve
