[QUOTE="MagnumManiac, post: 1444462, member: 10755"] A rifle that shoots 2 distinct groups is most likely not settled in it’s bedding correctly or has a barrel that is heat sensitive. Take the rifle apart and look for ANY scuffing or other marks where the action sits in the bedding, shiny marks in aluminum bedding blocks is a sign of movement. Weatherby chambers have freebore, often a COL close to max mag length is optimum, but you can try seating deeper in .005” increments to try and tune it. My 300 & 340 Weatherby’s had 3/8” freebore and worked well with the bullet at mag length. My 270 Weatherby works best with a .050” short of mag length, the freebore in this is 1/4”. My 375 Weatherby has 1/2” of freebore, it works well with mag length also. A bullet can be far away from the rifling and still be accurate, it just needs tuning and refining, often a seating change works alone, but I found a powder charge variation may also need to be trie. Cheers. :) [/QUOTE]
