You got it to stay back on the follower, nothing unusual about that. One major cause of 'Garand thumb'.
You're right. It is hard to get the bolt to hang back on the follower bevel alone.
(I just finished trying for a coupla minutes.)
In fact there must be something very seriously wrong with your Garand.
Send it to me and I'll if I can fix it over the next several years.
Im not sure I understand what you mean. If youre referring to getting the bolt to do what you have it doing, I can do the same on my M1 with little trouble.
Do you have the op rod out of its track?
