Changing a chamber for ammunition

[Hi-NV Shooter]

Yes I have been setting them up for full engraving. Have not experimented with the light engraving. Thanks for the advice.

Alex,

It wasn't advice just explaining what I have experienced. because of your CF background, I just thought you might have tried less engraving.

I don't want to start a big argument here but let me ask a question.

What is the primary purpose of the leade angle in the first place?

Answer that and it will give you the answer to shallow vs complete. With the exception to a couple of other factors thrown in depending on which you choose.

I'm not trying to make a riddle out of this just avoid arguments. Everyone is free to make their own decision.

Hi Tony,

You get no argument from me. I was just explaining my experience. as for what a leade does, I can only guess that it has to do with how the bullet will engage the rifling. a much steeper angel will need more force to set the bullet.
in any case could you explain I would love to understand and learn.

Lee,

The leade angle is there to ensure or at least try to ensure bullets engage the rifling in the centered position. A lead bullet regardless of shape cannot self-correct. If it enters at an angle it will travel down the barrel at that angle and become elongated on one side, and maybe out of balance.

The chamber has to be cut square and centered in the bore regard of leade angle.

But it doesn't end there.

It is critical that the bolt face be absolutely square with the bore. If you use the bolt to push bullets into the chamber/rifling, you want minimum play between your bolt body and action raceway. You also want to push the round the same way every time. It is surprising how closing the bolt differently can affect rounds on target.

If you try seating your bullets with your finger you will find it very difficult if not impossible to do the same each time. You will find some seat easier than others. That is because they are not all the same. You wish they were but that don't make it so.

Sometimes I get too caught up in the technical aspects of shooting and overlook the greater part of shooting and that is the actual act of shooting.

If you watch an accomplished shooter, you will see he/she is very machine like. They do the same thing over and over again in exactly the same way. That is the process of accuracy shooting. This is where the shooter makes the difference and not the equipment. Today, it takes more than just great equipment, it takes great shooting techniques.

It is a partnership between man and machine and they both have to do their part.

Oh great, now I have something else to worry about ... just joking.

Just want to acknowledge the knowledge bomb dropped here, I had no idea. I appreciate it when people in the know take the time to share. Thanks.

Thanks, Tony, for the explanation on leade angles and how it helps to align the bullet.

I shoot a Falcon and remember Bill Calfee explaining what the loading tray height adjustment screw was for like most I thought it was for aligning the bullet into the chamber. but he explained it was to align the bolt head/face so it will seat back into the same place when the bolt was closed.
Thanks again for the explanation and information.

Thanks for sharing your knowledge Sir!!

I agree, a smooth precise process is very important.
