[QUOTE="Pdvdh, post: 336577, member: 4191"] Chad, Glad you've joined this thread. Good to hear from another of the smiths that share on this forum. I've never seen a production line high-powered big game hunting rifle designed this way. Curious as to whether or not you have since you've seen a few bolt action designs over the years. It didn't sound to me as if the tang of MontanaRifleman's Sako was even designed to the size of standard recoil lugs. Mark stated "[I]The only place I can see where recoil is being transferred to the stock is in the tang area of the receiver which is somewhat thickened - about 3/16" and recessed into the plastic stock. That's it[/I]." Steel is strong, but placing the recoil lug at the base of the tang on a repeating rifle really doesn't make good sense to me because the action isn't symetrically strong on both sides. The ejection port side, combined with the magazine cutout underneath repeater bolt actions means that that side of the receiver is missing a lot of steel present on the other side. There's just a small strip of steel on some of my repeaters versus a solid slab of steel on the opposing side. And the tang is located such that the major portion of the compressive recoil force would be directed along the bottom of the action, right along that poorly supported section of the action. If the actions were symetrical (meaning one side was the spit'in image of the other) and sufficiently reinforced to prevent flexing and torsion, then the action would be better suited to transfer the recoil force of heavy kickers - my opinion from an engineering background. I know actions are beefed up on high powered target rifles. One way to do this is eliminating the cutout for the magazine boxes and go single shot bolt action. Now the action is only skeletonized for the ejection port. I think the bedding on light kicking rifles isn't so critical since they don't impart anywhere near the recoil forces of the 30 caliber magnums. I've got some .22's without any recoil lug. I'm looking forward to hearing Beretta's explanation. No offense intended toward anyone but I am questioning the guy that left the recoil lug out of the design of the Sako. I still think they boned it on the design and production of this bolt action. A 3/16" protrusion off the tang isn't a legitimate recoil lug - it's an oversight. PS: Chad; in your opinion is it possible to tig weld a recoil lug into the slot present for a recoil lug on the bottom of this Sako action without detrimental effects from the heat stresses of welding causing problems with the strength of this action? Thanks. [/QUOTE]
