Does your breech block stick up too much?

I have a no 1 45-70 and when the breech is open and you insert a shell the front of the cartridge rim hits the back of my breech block. You have to wiggle the shell some to get it past the lip. Does anyone else have this problem? I like shooting off the bench but would hesitate taking it hunting as your second shot might be delayed as you try to wiggle the rim over the breech block. Would be very interested to see if I am alone on this...thanks in advance..Joe

The 45-70 is a relatively long, straight-wall, Rimmed cartridge.
If you are lying the cartridge on the top of the breach block and pushing it forward, a technique you may be using if you are sitting at a bench while loading, the rim is likely to catch the breach block.
However, if you are standing up, holding the rifle in your weak hand with the muzzle slightly down, insert the bullet tip in the chamber and push the cartridge into the chamber - the cartridge rim probably will not even touch the back corner of the breach block.

I think some of your problem is the rifle is horizontal on a bench and you're loading from a seated position.

I agree with Petrol, I have a .218 Bee at the bench I have a similar issue and not with the .243.

The rim of the .303 can sometimes get caught up. The easiest way to feed it is dropping the round down into the chamber with the barrel almost vertical.

My only #1 Ruger is a .270 and I have never had your problem, and the .270 is a rather long cartridge. Keep yer powder dry.....robin

Mine sticks up about the width of a nickle or so. Its enough that some brands of 45-70 ammo will not go in, they just stick on the rim. I think I figured out whats going on. The Breech block arm is the part that cocks the hammer. When the hammer is cocked the hammer is still pushing up on the block. I found a used hammer on eBay and will play with it to see if i can increase the clearance between the hammer and the breech block arm. I didn't want to mess with the original parts in case i goofed it. Pull your lever down then push down with your thumb on the block. If the hammer moves, then the hammer is what is positioning the block. I hope by increasing slightly the clearance between the lip on the arm and the lip on the hammer where the two meet to do the cocking, the block will end up lower and be even with the loading ramp when the lever is in the down position.
