Each to his own. I have a 600 h&h & 577 h&h doubles both modern guns (1948 & 1988 factory completions ). I find the 600 less stressful to use & noticeably more impacting on australian water buffaloe. Will soon have a 500 to use & form my own opinion on which is best for me. If I have a serious cull to complete out comes the sako 338 plastic stainless steel using 300 grain projectiles. My greatest satisfaction is derived from a good kill with the double. It's like a greatl wine as opposed to a ordinary wine. It's all in the head.
