I'm looking for an OAL to start with for my 243 load. I'm using 41g of H-414 90gr berger BT to start with but am unsure of an OAL to start with. I'm shooting it in a Remington 700 Heavy Barrel. Any help with this would be awesome.
You'll get varying answer becasue all chambers are different. You need to purchase a Hornady O.A.L guage. That will answer your questions better than we can. Good Luck.
