Stupid question?

[GLTaylor]

Most folks who want to lengthen their throat are trying to get some of the bullet up/ further out of the case, trying to get the boat tail/body junction up near the base of the case neck. Especially so for our newer, longer bullets. This obviously affects COAL.

With the current setup I have to set the bullets really deep. I want to be able to use longer bullets. I can't even use vlds now as I have to set them way down.

As stated above, you need to consider your maximum magazine length before you consider lengthening the throat. However, it is usually possible to also have a longer magazine installed which could accommodate your interest in using a cartridge with a longer OAL.

I have 270 Win factory Tikka T3 rifle. Can a gunsmith use a 270 Win reamer to deepen the chamber?

The answer is yes, assuming you want to use longer bullets only without changing the actual chamber.
It only requires the actual throat be changed to allow for more length.
Be advised you might lose the ability to use the magazine due to the longer length of the cartridge.
Id personally be trying the longer bullets seated as long as the magazine will allow first, and if the gun shoots that way id just be shooting it that way.

Also you should consider if your 270 can even spin VLDs (twist rate) before making a chamber that will have an insane amount of jump for the standard 130g 270 bullet.

Absolutely correct if you have a 1-10 twist making the throat longer might have a adverse effect causing you not too be able too shoot anything accurately get some good gunsmithing advice ggod luck

What rifle model is this regarding? Or did I miss that info?

 

[Mc Fraser]

You missed it. It's a Tikka T3 in 270 Win.

I'm sure somebody will correct me if I'm wrong. I think if you switch to a AI style mag they are little longer and may allow a little more room to play with.

Its plastic I can cut a groove or replace it.

I wouldn't recommend cutting a grove in your magazine. Lol

Effects of Cartridge Over All Length (COAL) and Cartridge Base To Ogive (CBTO) - Part 1

Many shooters are not aware of the dramatic effects that bullet seating depth can have on the pressure and velocity generated by a rifle cartridge. COAL is also a variable that can be used to fine tune accuracy. It’s also an important consideration for rifles that need to feed rounds through a...
