[Rifle for B western]

So, I have a new WIN 1892...stock... in .45 Colt...why does it seem its is soooo difficult to load those dang rounds? I busted my finger nails, caught the tip of my finger in the loading gate, etc..I'm not lame and I'm very well versed in loading, example, I haver no issues loading the 38's in the 1866...anyone else have issues and anyone have a solution?
