Kenny Jarrett once stated that the 3 lug design was much easier to make accurate that any 2 lug design. Jarrett's own rifle utilizes a 3 lug design. This six lug design is just an interrupted version of the same thing. I bet it is very strong. The Weatherby Mark V's are noted for their strength ( I still don't like them). Sako's have been using 3 lug designs for years now in both push feed(the Model 75) and control round feed (the Model 85) and they feed well and are some of the most accurate commercial sporter rifles out today. The Browning's also utilize a 3 lug design and are generally good rifles.

The 2 lug design has the advantage of extraction camming. A 10 to 1 extraction ratio versus a 6 to 1 ratio for a 3,6,or 9 lug design is a significant increase in extraction camming power. Handy if things go South.

The funny thing about German rifles is that I always see them at gunsmiths because the wrist always splits. Calibres don't seem to make much of difference, 30-06 or .375 H&H, they seem to split because of there being absolutely no clearance in the wood to metal fit. I personally will not buy a German rifle with a wooden stock because of this. Heym, Sauer, Mauser,or a high dollar custom, it doesn't seem to make any difference. Even the 30 K$ customs I have picked up at SCI have absolutely no provision for recoil, shrink, or swell. Things that hunting rifles will experience if they are carried afield.
