throat too short

hello

hello i have a custom 7 ultra and the throat is very short. I am shooting 180 bergers @3.750 oal being set this deep puts the base of the bullet into the powder and reduces case capacity. Inorder to optimize the potential of this round i need to throat it .250 deeper. The rifle shoots very well but just is not at its full potential. I have found a hand throater from midway and was wondering if this is a job i could do myself or will i have to take it to a profesional.


thanks
Chris

Re: throat too short

I have never seen a throat anywhere near that much too short. I would take it to
a pro. Once you do it you can't go back.

Re: throat too short

This is NOT a home workshop job. You should have told your smith what bullet you intended to shoot before it was chambered. Take it back and have him re chamber with a longer throat reamer.

Re: throat too short

I would take it to your gunsmith and see if he will let you watch the operation. It is a simple method and tool use but, if not get impatient or lose focus, you will have a lot longer throat than you wanted. If that happens you can either jump your bullets or have the smith set the chamber back. I watched my local smith do my f class rifle. He let me borrow his throater becasue I had to move it out a little farther. The hand throater is essentially a precise drill bit. It is very sensitive to pressure. The more pressure=more material removed. Bottom line watch someone do the first one then if you think you can do it, let er rip.

Re: throat too short

So when shooting long VLD's like the 7mm 180 and the .308 / 210 where do you guys like to see the base of the bullet in relationship to the neck? I have noticed on my 300 wm's chambered with standard match reamers , that if you try to seat off the lands lets say .060" to .100" the bullets are really deep in the case. Is ther a "majic" place for the base to be.

Re: throat too short

ultimately I like to have the bullet seated with the boat tail junction of the bullet at the neck shoulder junction of the case. If your trying to fit it in a magazine you can run into some problems depending on the bullet though. Thank you Mr. Wyatts !!
I would recommend having let the smith that chambered the rifle for you throat it to a dummy round that you supply him with, with the bullet seated where you'd like it.. Don't be surprised if he charges you for it though since you might not have specified your intended bullet originally.
