JR= .318" JRS= .323"pastorp said:Does this take .318 bullets? Whats the designation for the .323 bore. Thanks, Byron
I'm sure someone does make .318" bullets, but personally i'd want my gun to more than go bang! In this type of gun i'd want the best bullet available, and use it on everything i'd ever hunt, both big and small, as you can't just "ajust the sights" every time you change bullets.I do believe that someone sells .318 bullets?
I used some H mantles a LONG time ago, but i'd rather have NP's anyday...Sir said:And you'd stick to your guns even if you could score some RWS H-mantels?
That "draw die" sounds like good idea, if you could do it yourself or had a handy friend or neighbor to make one. Is it any more complicated that a variation on a cast bullet sizing die? It would have to be well finished and would need some Imperial Die Wax, likely?
I don't want to be nitpicking, BUT....LOLSir said:I copied my other post for the 8 X 57 JRS. I do believe that someone sells .318 bullets? If you could tap into NORMA or RWS they would. In the US try some of the minor bullet makers
"8; is the nominal diameter of the bullet in milimetres.
57; Is the length of the case in mm.
"j"; or actually "i" for "Infantry". Indicates the case is related to the case for the issue army rifle.
R; is for "rad" or more commonly translated as rim. The only difference in case shape is the rim. You can reload with regular 8 x 57 dies. Usually a belted magnum shell holder will work.
S; indicates that the rifling is the deeper form required by the "S" or spitzer bullet. The normal bullet diameter for the "S bore" is .323 rather than the earlier bore of .318 diameter. When evaluating German 8 mm cartridges the presence or absence of the "S" in the description is VERY important. There are many older Drillings in 8 x 57JR in circulation. Usually they are in well used shape. Don't shy away if you find a good one as .318 bullets are available, and ordinary loading dies still work. The only caution is to stay with low pressures for older guns."
Seeing as how "northwolf" isn't nitpicking, i'm not either.... But, when it comes to bullets, you "draw" a bullet down, and "swage" a bullet up... So, if you want to make .318" bullets out of .323" bullets, you need a "draw" die...Brazos_Jack said:I have a prewar German drilling in 8x57JR and 16 GA. I bought 20 years ago. I ordered a bullet swaging die from Corbin at that time to swage .323 bullets down to .318. I used both Speer and Nosler partition bullets and got excellent accuracy. Killed a 6 point buck in SW Oklahoma with it the second year I owned it. I'm working overseas right now so I don't have access to my loading notes. I believe I was using 4350 or 4831 powder. I was using factory equivalent 8x57 data. Pretty mild, but I don't think it's smart to hot rod prewar drillings.
