If you pillar bed a .416 Rigby, do you still need the barrel mounted recoil lug? Is going to be used with 400 gr. @ 2350, or less, fps. Thanks in advance. | ||

Pillar bedding is done prevent compression during tightening action screws. And to lessen torque differences during stock swelling and contraction due to stock moisture changes. It would only minimally have effect on the front to rear force of recoil, especially since the action screws should have clearance all the way around the pillars. | |||

I restocked a CZ 550 in .416 Rigby with a McMillan stock and the answer I got directly from McMillan and also from Mark Penrod was that it did not require the forward recoil lug in the fiberglass stock. I consulted with several well known gunsmiths about the same issue in a custom wood stock and got different answers. Mainly it depended on how the rifle was bedded and whether there were cross bolts used in the front and rear of the stock under the receiver. THe real issue with the forward lug (as it was explained to me) is its never going to be properly bedded due to the expansion and contraction of the wood and barrel under various temperature ranges. Many CZs are shot with the factory stocks and forward lugs removed. YMMV | |||

Ky N, yep - in a mac composite stock, properly bedded, one may forego the 3rd lug. However, what I inferred from the OP was reusing the wood stock. having broken a few stocks, and seen more, a way to ensure longevity of the stock is a 3rd lug wood also expands between the action screws, .. and stocks dry out/get wet too... i haven't seen many CZs that aren't MOA in the big bores, even direct from the factory ... though i've seen a few shooters that aren't opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I reckon the best barrel lug system is on the Wby Mark V, it is only about an inch down from the action. I have never worried about using barrel lug on M70 or Rem 700. Both big recoil lugs and plenty of stock material behind the recoil lug, especially the Rem 700. On factor M70s in 375 and 458 I have fully floated the barrel including the barrel lug. Some don't shoot well because the barrel is often fucked by the attachment of the lug. For those I have had a take down screw into the lug and the bottom of the lug bedded. I never really had anything to do with CZs but if I did I would use a barrel lug in the big kickers. I have seen a BRNO converted to450 Ackley and no barrel lug used and the stock split. I tend to agree with jeffeosso on this. | |||

I have seen some rifles with a metal plate inletted to contact the recoil lug and the rest of the inletting idexed off that plate, which was screwed or fiberglassed (or both) into place behind the recoil lug. Seemed to work pretty well. | |||

Those Ruger Magnum rifles were basically like that although the action had no recoil lug but a slot for the plate. Not sure but I think the ordinay Ruger in 458 had the same. I had a Mark V Wby that was a 416 Wby and I had the sides machined off the recoil lug, about a 1/4" per side so the recoil lug went into a slot in a plate several inches long. I did it because I wanted different barrels in the 378 based calibres and so the barrel lug was not practical. I would never have a Mark V in a big kicker rely on the recoil lug. The lug is plenty big, about M70 size but very small amount of stock material behind the lug. If I was doing it these days I would just start with an Accumark and the allow insert. | |||

If the stock of wood (walnut or laminate or whatever wood) does not have an integral metal bedding block surrounding the bottom of the action entirely, then use a barrel lug as secondary recoil lug, with a hidden or visible crossbolt backing up any recoil lug and the magazine well web, and pillars. My rule of thumb is to do that with any rifle capable of 5000 ft-lbs or greater loading, and that includes the likes of a .375 Wby. I do that with McMillan or Brown Precision stocks too. Tupperware or Zytel boat paddles are let go without any secondary lugs, and I have not lost one yet, darn it ! | |||
