After almost 5 hours of continuous working on the mag I have finally finished. There were two problems with the mag seating and removal. After the stock was removed the mag would still not fit in the upper because the back of the mag could not get past the post. The ear of the front catch on the mag was a tad bit to long. Filed down (approx 1/64") with a dremel rotary sand paper fitting and with the stock removed the mag would finally seat in the upper with out a mallet. Started putting everything back together and the wood "mag well" was so tight it would not let the mag fully seat without binding. Again the dremel and some light sanding and everything went back together like it is supposed to. For once I did not take to much off and it looks like it will function as intended. Will go shoot the SKS on Saturday after my ammo comes in this Friday. Speaking of ammo; I ended up getting my ammo from aimsurplus which had the best price I could find for 1120 rounds. I paid $182 but the shipping brought the price up to $225.36. The Silverbear would have been $230 (for 1000 rounds) plus shipping and is not brass. Glad I ordered when I did for I think they are sold out now! If someone knows of a better place to purchase ammo I am all ears!
Their take on the ammo is:
Beautiful Surplus Yugoslavian 7.62x39 ammunition. This is the best shooting 7.62x39 ammunition available. Features a 123grn lead core copper jacketed bullet, brass case, and berdan corrosive primer. Packed 10rds on a steel charger (stripper clip), 40rds (4 SKS chargers) in a box , and 1,120rds (28 boxes and 112 chargers) sealed in metal tin inside of a hinged latched wooden case. At these prices... while supplies last!
I have used Silverbear in my ARs and would have purchased some more especially since it is non-corosive but I am not that concerned about corosive ammo in that I clean after a range trip or hunting. Thanks for the info guys and wow I am glad that is over!!
