I appreciate the responses fellows.
My response to 86er is that I don't have any drilled and tapped holes on the side of the receiver. The only holes are in the moveable bolt at the rear, and are not tapped? It looks like there may have been a special type of peep sight that as an option could be installed at the time of purchase. The gun Ser.# is 1335 and checks out as production date 1935, which if i'm not mistaken is the first year the Model 71 was made. I enjoyed installing the Lyman Tang sight, and it only required drilling and tapping one hole in the upper tang. I did make one other change to compensate for the aging factor, that was to install a fibre-optic front bead sight. Yesterday I got a four-point buck up in the hills near my home. Everything worked perfectly, the shot was in thick bush with a deer that had already spooked. I stopped him momentarily with a grunt, and the bullet went exactly where I aimed! I think I'll stay with what I have, can't imagine any improvements. The only critique I could have is that I don't like to carry the gun with the tang sight in the up position and I have to develop a quick habit of flipping it up as I shoulder the rifle.
Gunnut69, your thread has really got me thinking this whole concept of reloading over. First of all, because of the number of cartridges that I have in the 200 grain Silvertip, the only need I have of reloading the .348 cartridge would be to acquire a 250 grain Grizzly smucker. After seeing the effect of the 200 grain Silvertip on a large Mule Deer, I now have no doubt that this is also more than adequate for Moose. Maybe I just can't justify the cost of setting up to start loading. I also find that when I target shoot, the recoil of the factory loaded .348 is how shall I say, substantial, but when shooting at game of course I don't give it a thought. If however, I load the 250 grain bullet ahead of about 60 grains of powder and crank out 2300 fps. flinching could result. What I need is just a couple of boxes of 250 grainers and that would last me a lifetime (Im 62). Perhaps I could offer 4 boxes of this collectible ammo. for two boxes made up to my spec.s with the Barnes 250 grain bullet? I,m open for suggestions. Thanks for the info. and advice.
