My favorite load in the .243 for deer size game is 45 gr IMR 4350 behind a 100 gr Hornady or Sierra Sp. Today the handbooks don't give this heavy a load. Use your head and work up slowly. Your rifle might not handle it. It chronographs from my Pre 64 FW M 70 at 3150 fps. It is accurate and I get 1 minute groups most of the time. However, I am not an accuracy nut. I prefer to settle on a minimum accuracy requirement for big game of 1.5 min. When I reach that I prefer to have increased velocity for flat trajectory and long range killing power. I wouldn't personally settle for less than an honest 3000 fps in the 6mms. I have read through the years of criticism regarding the killing power of the 6mms on deer size game. The loads used are usually around 2800-2900 for a 100 gr bullet. When you add another 250 fps or so you have a different cartridge. Again I caution to work up loads carefully. You only get one set of eyes, etc. Jerry
