Peoples on opinion between tapco and promag magazines for the sks

in WW1, the Colt MG would always/often drop short the first round….the gunner just took that one out of the belt…lol. maybe it`s the same with these mags….
mag may be pinned to 5 too tightly. test by loading one rd less, if they feed fine, the lips on the mag may just need adjusting
the old plastic issued mags for the C7 used to not properly feed the first round with a full load of 30, we used to load 27/28 rounds and no problem.

The reason I ask is because I have a chinese sks with a tapco stock on it, with tapco mags. Brought it out to the range the other day and the magazine fits nice and snug into the stock. Problem is loading the first round into the chamber i have to hit it with the charging handle two or three times in order to get the first round in. Once that round is in there is no problem with the remaining four rounds being jammed at all. So wondering if someone could help shed some light on the issue and their opinion between the two magazine manufacturers.

Good point about pinning. Tapco appears to use a rivet now on new production 5/20 mags as opposed to a vertical post(?) inside restricting the spring. Not sure if that matters.
 
Had the exact same issue with a tapco mag that was pinned too tight with the internal block, had to disassemble the magazine and file enough material off the block so that it would feed 5.5 rounds, no more issues after that.
 
I have a tapco stock on mine not alot of use and my picatinny rail has cracked down the middle, one of my mags have a cracked lip
