I have been looking at building a 7X68 rimmed in a replica 1885 high wall.
The goal would be to have a rimmed case for extraction and shoot the 175 and 180 gr VLD Berger bullets over 3000 fps with Retumbo or VV N-570.
What can you tell me about possible sizing dies. Do you know of a bushing die that I could use for routine sizing in 7mm X 68 ?
What size die are you going to use in your 8X68S ?
I do not need "dies". The traditional seating die will not work with VLD bullets. I will use a Wilson seating die created with the barrel chambering reamer.
Berger VLD bullets 7mm bullets are .284 in diameter.
The 7X64 or 7x65 rimmed or rimless will not provide the velocity for big game hunting at long range with 180 gr bullets.
What I am looking for is a bushing size die so I can control neck tension and partial sizing.
What are you going to use to size?
I can use 6.5 X 68 rimmed RWS brass.
I would build a 6.5 but I already have four in that size.
The Berger is meant for reduced true "LRH" terminal velocities not 300m...for 300m the best bullet would more likely be the Barnes Triple Shock
