Whats the barrel twist on my Remington 600 .243?

I just bought it and dont have it back yet to see what year it was manufactured. It has a 18.5" vented rib barrel and I'm guessing it was made around 1964 to 1968. I was wondering if the barrel twist was slow or fast? I'm guessing its a one in 10 twist? I'd like to shoot 55g Noslers through it all the way up to 105g bullets if it will stabilize them.

To my knowldege rem never made a 10 twist for a 243-6mm, if your rifle is old enough it will be 12 t, if after rem changed it will be 9 1/4 twist. ed
 
I learned to never take someone else's word regarding twist rate after buying a brand new rifle that got out of the factory with the wrong twist barrel.

Best to measure it your self with a cleaning rod and piece of masking tape.

OT, but since this comes up about once a week, I wonder if people would read it if there were a how to determine twist rate sticky?
A FAQ thread might not be a bad idea either, for answering redundant questions.

Luck with the old Remmy.
Those are great little rifles.
 
it is a 9.25" twist. speed and twist rate factors into stabalizing a bullets. 55-100 grainers no problem. the 105 amx MAYBE in a 26 inch barrel.
 
The greenhill formula puts out .89 inches as the longest bullet for a 1:10.
A nosler partion 100 grain needs a 1:8.86 twist for good stability. So around
90 grains is where a 1:10 will completely stabilize most bullet designs.

Once again,,, "Measure it yourself".
Takes two minutes and a piece of masking tape for crying out loud.
If you don't own a cleaning rod, then by all means, continue to take the word of total strangers on the Internet.
While well intentioned,,, hear say is just that.

EDIT; I just reread your op and remembered that you don't have the rifle yet.
Same answer though.
"Measure it your self when you do have it to be sure."
