Need a Measurement on Norma 416 Rem Brass

[intj]

I need to know the diameter immediately in front of the belt on unfired Norma 416 Rem brass.

It may allow me to save my current barrel. All I have now is Remington 416 Rem brass, and as I have seen with other cartridges, Rem brass made 20 years ago is sometimes below min SAAMI spec, which causes all kinds of problems. So I either need larger diameter brass or I need to chamber a new barrel.

It would be about 10 days before I could actually mic some brass, but,,,what problem are you having?

I shoot a 416 Remmag mod 70 as well and have the same click from reload 3 or four you mentioned in the other thread. The rifle is very accurate and has been 100 % reliable.

I don't like the clickers on firing 3. They are caused by undersized brass in an oversized chamber

Thanks!!!

That is only .0015" larger than mine, which isn't enough. Given this rifle as earned a forever place in my safe, I guess It's time to buy a reamer and fire up the lathe.

I too don't have any reliability issues, but I hate clickers......

Maybe not:
Have a gunsmith turn your barrel back one turn into the receiver. The smith will grind the equivalent off the rear face of the barrel. Then, due to a moderate amount of metal to be removed, a .416 finsher reamer of proper measurements would restore your barrels chamber to SAAMI standards.
Assuming the rear few inches of your barrel is cylindrical, - any bedding will not be severely affected.

I have my own lathe, and I'll just put on a new barrel if needed. Rechambering is about the same work as cutting a a new barrel, and with a new barrel and I can guarantee the chamber will be cut straight.
