I have taken deer and an elk with the 210 Berger from my 300 RUM Sendero with great results out to 700 yards. After screwing a new Douglas 28" custom barrel on the Sendero recently I have discovered that the Bergers don't shoot an acceptable group until I begin to see pressure signs on the brass (ejector marks). I recently tried the 208 gr. A-Max's and have found a load that shoots extremely accurate (1/2 MOA and better) but am wondering how it will perform on deer size game up to elk and black bear size game. Has anyone any experience (good or bad) with the A-Max's? Thanks in advance for your response!
