G,day all.
In the process of purchasing a JP murray carbine in 58cal.Was wondering if anyone has got and/or shot one,what powder charge,projectile etc.Thinking of using 80g of FFg with a .575 500g minie as a starter.Any advice would be appreciated.Thanks Justin :thumbsup:
 
I have had two and had no luck with either one. I have used patched round balls and Minis in both. Due to shape of stock it is very hard for me to get a good sight picture. Neither one ever gave very good accuracy. Good luck with yours.
 
Most competitive target shooters use about 40-50g ff or fff powder. The minie ideally should be 1 or 2 thous. under bore size. If you cant get a good measurment then stick the minie into the muzzle enough to cover the grease grooves and try to wiggle it. there should be very little to almost no wiggle.. Make sure that the grease grooves are coated with a good black powder lubricant. I cant stress that enough. Poorly lubed minies can shear the skirts off of minie balls which usually requires a trip to a gunsmith to remove the breech plug. For more info I advise going to www.N-SSA.org and log into thier forum. These guys are the minie ball pros and are receptive to new shooters. Cheers! Bob E

The service charge for a .58 Springfield musket with a 42" barrel was 60 grains of 2f and it can be uncomfortable after a while. 80 grains in that light carbine would hurt. A 325 grain mini over 40 grains of 2f would be comfortable and very accurate and a 24" barrel is just too short for a heavy charge. A .575" mini is way too small and will keyhole. Slug or otherwise measure your bore and size your cast mini to 1 or 2 thousandths under that and use a quality firm lube in the groves. The bores vary and can be as large a .580". I just checked my vintage Zoli Murray with a set of plug gauges and it is .578". To the best of my knowledge all Zoli .58s were rifled on the same machinery and have a slow twist, about 1 in 70".

hi, lowkew,

i've had mine for quite a while but haven't used it much lately.. iirc, i used the cast mine which has 3 grease rings a.k.a. the .575213-OS (os for "old style" ?) or .570 prb all powered by 55-60g fff (or @ 70g ff) goex.

typically, it was used for targets at 25yds., and i had no complaints.. i'm sure the muskatoon is more accurate than my eyesight.. some ppl here have even used them for huntin wild hog - :shocked2: wow !

personally, i found the size and shape of the stock to be near perfect since i'm kinda small anyway (5' 6").. the fit and finish of my euroworks model is beautiful and all that brass shines up real sweet.. since they aren't being produced by euro anymore, your zoli would be quite a find indeed.

enjoy it while you can,
~daniel~
 
The one im looking at has a 23" barrell with a 1 in 60 twist.Thanks for all the info.
 
I shot one of the Euroarms version of the JP Murry in NSSA for awhile. I like the Lee 575 traditional minie best with 40 grains. It shot very well, but I went to a Smith Carbine so I could be quicker and more competeative. The smith shoots no straiter than the Murry, however. I never shot it with 60 grain service loads, so can comment there. It was hell on clays with the target load.
