Oh yes , the russian semi auto sporting rifle is the medved. had heard it that rifle and ammunition is exported to bulgaria but not more about it. the russian cartridge is very hard to find as a collector round here. it will be never exportetd in shooting quatity's in the evil empire here because the gun law only allow CIP proofed ammuntion, exept collector catridges.
even collector's where I buy some rare rounds asking me if I have it. some reloading points were be spoken in the M 95 moose killer post. the die set will be come from CH4D again, I have now 100 new brass cases and 60 Sako factory rounds. brass can be easy resized from 7,62x54r brass if you have it. the only brass case I found in my stuff was a russian sniper case with "166" headstamp -- LVE military load. resizing with the CH4D die is like making 9x57 from 8x57 brass.
the masterplan is to stay with the Kemira/ Vithavouri load. only problem is that nobody exported the 16,6gramm Sako softpoint bullet, maybe bokmal can again make a packet for me this year. the one rifle/ one load concept isn't so bad at all. for double rifle's it worked some years with satisfaction.
Wim Degol in belgium makes great bonded core bullets on demand, any size and weight, equally to woodleigh's in quality. will be a good idea to order the 16,6 gramm bullet also from him.
for bokmal information about the year 1944, the so called "peace" with the soviet union was made on the 19.9.44. iirc the now more or less obsolete but very interesting 7x33 was also develop in 1944. it seems to be that there some guy's in he finish ammunition industry were very quick to locking for a new peace time production.
did you have a pic of a 7x33 rifle, bokmal? I never see it before, believing it was sometimes THE cartridge for hunting wood grouse and black groose in Finland
