I bought a new Ruger American 450 Bushmaster recently and when I tried to sight it in the cartridges would not feed from the magazine into the chamber. After examining the magazine I noticed that the back of the Platform ( or follower ) in the magazine ( or clip ) was sticking along the back wall. I disassembled the magazine with a small screwdriver by prying the bottom plate rearward. I sanded about 1 mm (1/32”) from the back edge of the Platform and rounded off and smoothed the edges. I bent the back of the platform up a little and reassembled the magazine. IT WORKS PERFECTLY. Here’s some photos.

After receiving the replacement magazine from Ruger I noticed that the platform was reversed from front to back. (The bullet shape is facing backwards) Take the magazine apart and reverse the bottom plate on the spring.

Now I’m worried if my rifle is really sighted in. With the original magazine not feeding a cartridge into the chamber I sighted in the scope by inserting one cartridge at a time by hand. I didn’t fire it again until I hunted with the new magazine and recovered a nice buck that went 30 yards but thought the shot hit lower than I aimed. Back to the range. Thanks for all the input guys.
