This thread may have changed my luck, (hopefully), with my magazine issue that I've been experiencing with my Remington Model 7400 in .30-06. (See my above post).
I started poking around the Internet this morning having my coffee, seeing if I could find an old style, (read one piece bottom and sides), magazine for my Remington 7400 in .30-06. And low and behold I came across a little mom & pop operation in Galesburg, Illinois (Simpson Ltd.), that had 3 brand new, (still in the original packaging) old style Remington 7400 magazines in .30-06!
The price wasn't bad at all for $110.00 for all 3. ($124.00 including shipping). That comes to just $41.00 each. I paid almost $40.00 for a 2 piece new one from Midway. And the damn thing wouldn't even fit in the gun. The newer 2 piece one's claim they'll fit .30-06, .25-06, .270, .280, and .35 Whelen.
These are stamped .30-06 ONLY. From what I've read the older one piece walls and sides magazines had much tighter dimensional control. The newer one's are all over the map. These are the one's I bought.

And these are the newer 2 piece models of the same magazine, that are hit or miss as far as fit and function. And Midway wants almost $40.00 for a blemished one. And that's not including shipping.

When I get them I'm going to crank up my 7400. I'm hoping these magazines will do the trick. The older one piece magazines are hard to find used at any price. Let alone find 3 brand new in the original packaging. For once I was at the right place, at the right time.
