I did pick up some hunting ammo for my M91-30 it was wolf gold 180gr its boxer primed brass cased ammo. Has any one reloaded wolf gold ammo?
Wolf Gold Line ammo is made by Prvi Partizan,Wolf is just an ammo importer and contracts out all there ammo to various mfg. As far as your question goes if its brass case and boxer primed yes you can reload it.
Subsonic rifle rounds are typically for suppressor use. There is a real danger of detonation if no case filler is used and there is a real likely possibility of tumbling as it leaves the muzzle.
Unless your running suppressed there is no real need for taking your rifle down to the power level of a weak 38 special.
There are some truths and some myths to what JonM is saying,however you have to take several things into consideration when developing subsonic rds. choices as to the powder and bullet type as well as case prep and philosophy of need and use all come into play.
I shoot sub-sonic rds. in all my centerfire rifles (cast bullets) one because there accurate,quiet,cheap to make and shoot and it gives me/you the ability to turn one rifle into a multi use weapon for taking anything from small to large game when you may find yourself limited to just one rifle or only rifles in 30 cal. or larger.
As far as suppressors go I don't own one or have a need for one since my sub-sonice cast bullet loads barely break the 950 fps. range in all my rifles,plus lead and suppressors don't work well together. They are useful if you want to quiet the report down further and are using jacketed bullets. For the sake of discussion without getting into lots of detail shooting pistol velocity loads with shotgun/pistol powders in rifles longer barrel basically acts as the suppressor absorbing both the bullets velocity due to friction and pressure decreasing more rapidly in the longer barrel,this also cools the hot gases as they expand and decline more rapidly in the longer barrel rifle.
Powder wise I use fast to med-fast burning shotgun/pistol powders these can be used in low volume with many 30 cal. rifles calibers with a a variety of bullet weights. They also ignite very easily and require no filler as long as you work within the safe load density range. The real problem of detonation or SEE Secondary Explosive Effect and most notable Hangfire comes when you go below a safe load density with a given powder.
For all my sub-sonic load in 7.62 x 39 and 54r,30-30 and 300 Sav. I use one bullet and one powder this bullet as well as the powder can also be use in 06 and 308 cartridges with equal results. For powder In all these cartridge case I use Bullseye it readily ignites with no issues in large capacity cases with standard or magnum primers if you so desire to use those,these loads need no filler. For the x39,case you can start at 2.7 grs. and go up to 3.0 grs. in all the other cases mentioned you can start with 3.0 grs. and go up to 3.5 grs. these are not max load but leading may become an issue if you push them over the 1K fps. range since I cast my bullets from pure lead. I get excellent results in the X39 using the 3.0 gr. load and 3.5 grs. in all the rest.
My bullet of choice is the Lee 32 cal. .314 90 gr. tumble lube SWC,bullets can be cast from pure lead with a little tin added if you like or cast them from 50/50 Lead/WW alloy. In the X39 and 54r my rifles like a .314 dia. bullet. I TL once run it through the Lee .314 sizer and TL once more before loading,for the 308 cal. rifles I use the same procedure as above but size the bullets to .311 in my Lee sizer. All bullets are roll crimped in the top lube groove. If you don't cast and a .314. dia. lead bullet will be useful Hornady makes a swadged 32 cal. .314' bullet that may work for you.
Here is an example of my 30-30 subsonic load using said bullet and powder and Win. LR primer.
