I have a Remington 700 varmint and I was trying to develop loads with the 178 gr ELD-X. Using 42.6 gr Varget with a COAL of 2.800". I could not seem to group to well, and that charge was my best. With this bullet, my lands are at 2.924" OAL, and my mag can hold 2.845". Is there any tips or tricks you guys know of that do not include switching bullets or getting new base metal etc.?
