I have a Remy PSS in 243 with a 9" twist barrel. According to Hornady the 105 gr A-Max should work in this barrel but does anybody have any experience with it......do you have a load suggestion? Any ideas appreciated.

Not yet, I am planning on trying it in 6mm Rem. I have a friend that really likes this bullet in a 243AI he has though.

POst that ? here-- http://www.longrangehunting.com Lot's of guys there that shoot that bullet.

Suggest you try Reloder 22 . Gives excellent velocity with heavy bullets in the .243 .
Have heard that the 105 A Max can be excellent if you sort them by ogive length ? Apparently they're inconsistent . Haven't got the tools or patience for this myself . I thought that given the "A" is supposed to be for "accuracy" that they should do that at the factory .
Some say that VLD bullets like the 105 A Max must be seated into the lands . This rules out using the magazine on Rem. short actions .
Have a look on 6mmBR.com
