Before developing any load I do a lot of research from four or five reloading manuals, consult with my mentor, scour this site and start gradually and see what works best for my particular purpose and caliber. I am not a master reloader by any means and I am having some difficulty with a starting point for a 7mm Rem Mag. I am using Barnes TTSX 140 GR, Hodgon 4831(based on a recommendation from the good folks at Hodgon), Winchester Brass and Remington 91/2M primers using a Winchester Model 70 with a 24" barrel. It seems every manual suggests a different starting and maximum powder charge and a many varying C.O.A.L. measurements. Can anyone suggest a good recipe I can use to start running through the chrony before wasting too much powder and projectiles? I plan to use this cartridge for 250+ yard shots on deer and hogs. I do not think I will go much beyond the 350-400 yard mark until my markmanship can be ruled out as a variable as I do not want to just injure an animal. Dead Right There is what I am looking for. It seems my 308 cartridge recipes were much easier to design and they have proven very consitent with velocity and accuracy. Thank you everyone. p.s. Sorry for being so long winded but I felt the more information I gave, the better the "teachers" in this forum would be able to assist me.
