Rob,
I currently have the PII with a standard trigger, covered with a Austrian Swarovski Optik ZfM 10x42 sniperscope. I opted for the Harris "SL" bipod ILO the VersaPod, strictly as a concession to weight & compactness. The system as described, has a strong penchant for Federal Gold Medal Match - 168grain (GM308M),lobbing a 3-shot group into the same jagged hole (each overlapping the other two) at 100 yards. I don't think there is anything wrong with that kind of performance, except that it's indicative that the inherent precision of the system is hindered by my ability to use it more accurately.
I don't understand the problems others have described with the SSG69. I've never previously heard of anyone having difficulty with them. During the latter '70s I used one in .243WIN, w/ double set trigger & a 12x Redfield to routinely vaporize prarie poodles out to 400 yards.
However, I much prefer the P-II series bolt knob to the butter-knife handle of the '69, especially when cycling the action for a fast follow-up shot.
There is a MATFLCS-III looming on the horizon, wanna come along and wring it out?
