Re: Savage type barrel nut on CZ action / swich barrels
Here is my answer: DON'T do it until or unless you have someone watching and checking your first few times that knows what they are doing.
I know nothing about the CZ bolt face. Savage is a NO BRAINER as every barrel has a finite thread count and the breach of the barrel is flush without a bolt extractor cutout. The hex and the new spanner nuts also have a finite measurement depending on application. Simple math or cheat like me the first time and measure the thread count and the nut of a pre-existing setup like Savage.
I am not prepared to go any further because one of our barrel makers out there still can't get the thread count correct. A shipment of barrels went out and the thread shank did not have enough threads so with nut they could not thread the barrel deep enough to correctly hadspace. I also have three barrels from that maker that have too many threads requiring me to go from an oversized .250 lug to .375 to cover up the threads.
What I am saying is, you are playing with high explosives and I for one never chambered the first few times without a friend looking over my shoulder. I still have two eyes and ten fingers and I really am allergic to pain. This comes from a machinist who made a living doing precision work.
Don't do it is just my opinion.
