Ran into an issue with the magazine floor pate on my Rigby Big Game in 450 Rigby over the weekend.
I have put quite a few rounds through this rifle since buying it only 6-7 months ago and the rifle has been flawless up until this weekends range session. All of a sudden the magazine floor plate would pop open under recoil every time I fired the rifle. After closer inspection I noticed a small grub screw in the floor plate (pictures below) at first I thought maybe the grub screw was not wound in far enough but after some experimenting it turns out it was wound in too far and wasn't allowing the floor plate release button to come all the way back out when the floor plate was closed. With the release button not being able to come all the way back out with the floor plate closed and rounds in the magazine putting downward pressure on the floor plate it would pop open under recoil.
I'm glad this started happening before my buffalo hunt in a couple of months because it would have been a very difficult fix in the field, the grub screw had some good thread locker on it, couldn't even move it at first. Soaked it in brakekleen for a few minutes and I could eventually start moving the screw in and out, I now have it in the right spot for the floor plate release to go all the way back in with the floor plate closed and have test fired it with a full magazine and no more issues. Will be getting some light duty thread locker to put on it tomorrow to make sure it is locked in place.
Not sure why it hasn't had the issue from brand new as the screw definitely has not moved, it must have just been hanging in there all this time and now with a tiny bit of wear and things settling in it must have been enough for it to just start letting go.
I would be interested to hear if any other Rigby owners have run into this issue.
