.58 traditional rifle accuracy?

[Ranger J]

Has anyone had good luck getting accuracy in .58 traditional rifles?  I have had two—a CVA and a Cabela’s model and both seemed to be over bored.  Both patched round balls and conicals seemed to slide down the barrel much easier than on my .50 and .54 guns.  Light loads in the 50G neighborhood did all right, especially in the Cabela’s, but when I tried to shoot hunting loads of about 90-100 loads the groups really opened up.  Both Maxi Hunter and REAL bullets seem to load much too easy, that is going down the barrel with too little resistance. I would like to shoot the Cabela’s, which I still have more, but am put off by the lack of accuracy.

  i unknowingling got a chambers .62 becouse i wanted bigger.. bigger is better right?  well after a year and a ahalf of lots of work and troubles, iv found out quite abit about big bore ml rifles..  the .62 is a grand caliber partially becouse you can get .600 balls, .610 balls and you can cast them with very hot molds to get  .603  and  .613 inches in diameter.. also i can buy  20 guage wads.. i was cutting pathces like crazy at first and had to use 20 gauge fiber wads inbetween patched ball and powder to hit anything..  last winter i found that if i soaked the patches in the lube several days before shooting it made them alot tougher and theywouldnt cut anymore.. the .016 deep rifling is working in nicely....  track of the wolf sells  .020 tight weave patche material and its great stuff..  i use it and .613 balls and hammer them in with a small wood mallot to start the ball..  then i can shoot 100 gr 2f in hot weather, 115 in moderate weather and 125 grains 2fg in cold weather to get similar impact points and pretty good accuracy.. i think the impact differences is more due to recoil difference in different temperatures ..  it really swacks a deer with almost no meat damage if you hit them right...  aprox 335 grain ball at 1450 fps muzzel..   on at 10 yards, 2 inches high at 50 yards, on at about 80 yards and 2-3 inches low at 100 yards.. so get some thicker pathces and if you can some bigger balls.. there is a guy in engleand that will make moulds of what size you want.. try tanner moulds  or tanner molds iin your search engine... you have to cut the sprue your sellf..  if you get the tight ball fit you will need to wipe between shots or the ball will get stuck half way down...  if you can shoot mini slugs then you probably have shalow rifling and for round ball you will need to wipe and have tight patch/ ball in my way of thinking.. but keep at it and you will get there.. .58 will be an awsome caliber.. be sure twist is 1/48 or slower...  dave.

I guess the CVA .58 is a Big Bore Mtn. Rifle ?.  If so it is a 1-66 twist & will shoot a RB very accurately.  Try 75 grains of FF Goex, a .570 RB with a .015 Oxjoke or .017 Pillow ticking patch & some Lehigh Lube. (Be sure it is the New  Lehigh Lube & on the back of the bottle it will say Lestom Labs as the maker). With that Combo, mine will cut 3 in a cloverleaf group touching at  50 yards.  You will find with RB's  normally the most accurate load for the rifle is going to be on the lower velocity loads, unless you want to hammer the balls down the bore with a super tight combo.
 If you are deer hunting with it, 75 grains of FF will drop a deer in a heartbeat with a well placed shot, as I have done it many times & do it every year 4-5 times a season.  My objective is an accurate load so shot placement is good, and also for ALL of the energy to stop IN the deer, not blow thru him.  I shot one on Monday & it ran 20 yards.  I shot another on Tuesday & he dropped where he stood. I also have a .575 mold for this rifle but have never cast them as the .570 balls shoot more accurately than I can hold it.

Unfortionately I don't have the CVA rifle anymore but do still have the Cabelas.

Allot of times when you start shooting those heavy loads, you will blow the patch ( actually blowing the seal the patch is making) and accuracy goes to hell in a handbasket.  Try a thicker patch & you also can try a wonder wad or just wad up a greased patch & shove it down before the patched ball,  & you may find a substantial difference in the accuracy of ball or bullet.  And you don't need 90-100 grain loads to kill a deer with a .54 cal.  75 grains of FF is more than adequate to shoot thru them, I shoot 3-4 deer a year with one & it does the job with a RB.

.020 patch with a 62-cal wonderwad or two should help. Maybe even a .575 ball instead of a .570. You can try changing powders and/or grain size. Even a different lube may help.

Lots of stuff to try.
