| 3UE/2- 17R. No Iron sights on this one, originally part of a pair, The .416 Rigby does have Irons, which I believe in. This one was to be a .375 H &H. It got changed to a .340 WBY before I had the Mag box made. Owner already had 2 .375's and inheirited a 3d, Didn't have a 340, so why not? and scope only. I know the Rigby went to Africa (D'Arcy stocked it,too.) After making the box regular 3.625 length so he could hang the bullets out further than the long established not over 3 9/16" long .340's, I had to make still another because Wby really HAD changed the specs. to need a 3.725 inside length box. I didn't get invited into what ever led to it's being made into a .416 Rem. You who have read my posts here simply won't want to believe it true, but I tend to get terse and sharp tongued even.......when requests that don't compute get made. Speculation, and right to .45nut's comment earlier about the responsibility of having just one of these. A Rem .416 could use the 340 box ,just fine, you could make a longer OAL load and it might sell better. Having both a Rem and Rigby to shoot one after the other settles things rather quickly. There are 3 main components to recoil. Initial thrust, acceleration recoil, and rocket thrust when the propellant gases reach the air at the muzzle. You feel all three at once as a simple reaction. To this you can add counter rotation, the reaction counter the rifling twist, and in a right hand twist, 1:14 in the Rem and a faster burning powder to move a 400 gr. projectile to match the lazy old Rigby and the 1:16 twist I use for it makes the Rem. uncomfortable by comparison. Expln. Counter rotation- Rifle wants to spin in opposite direction to the rotation of the bullet. Most noticible when heavy bullets and fast powders are employed. Felt recoil along side face, sometimes bruises to match. Not really pronounced between the 2 rifles but If you have them to shoot a lot,you would notice the difference, and at 2375FPS for the both. A fat old Rigby at 16 twist can and often does print 325 through 410 grain bullets in the same group out to 100 and sometimes even to 150 yards. The Rem at 14 twist is a bit more finicky. Pfeifer, Square bridge. I need a flat near .845 wide on the bridge. Most of the Rem Mod.17's clean up the flat for the old sight spring about .025 higher than the top of the ring once you have precisely ground the ring to get rid of the Tsunami like wave style polishing done to suit the Military. There is considerable variation in the blend from the side of the ears to where this meets the radius on the side of the bridge and the left hand side wall. There are 2 flat grinds tangent to what ever radius cleans up the side walls projecting up to the flat top of the bridge allowing this width. These flats are Plus or minus 5 min of angle to 20 degrees as it suits the needs.. One flat per side. The approach from end of the bolt stop up to the flat top is a curve and this radius is made by the wheel diameter.. The only welding done on the bridge or its sides is in the clip ear pockets, and not much, Only to insure that there is no void showing up in the recoil tab cut for the lever release scope rings. The dovetail bases themselves are made of AISI 4340 Chrome Nickel Moly steel hardened to Rockwell C 38 and milled in that condition, then they are ground for the rear base and milled for the front base to the required highth and ring radius, Ring base is lapped, then both are soldered to the receiver using regular 6x48 screws and these are then replaced with screws made to exactly fit the bases from remnants of the same base material, and these are cold swaged to the bases and this part is then ground causing the dummied off screws to disappear into the base top surface. You must have some surfaces to work with ,register from and clamp onto for these operations and that is all done in the grinding, as a preparation for subsequent doings. It is always hillarious when I hear the comment about "He even grinds and polishes below the stockline!". Hope I answered most of the questions |
