Which barrel contour??

[satchamo]

I’m putting together a 7 PRC on a tikka action and I’m a bit overwhelmed by the amount of different proprietary contours available. I am looking at having UM chamber an ACE barrel amongst a few other options.

This will be strictly a hunting rifle and I plan to do 18” in because I have a DD LTI can it will be wearing (I know it will be slow and I don’t care). So 5/8 threads at a requirement.

I’m not looking for a pencil barrel but I definitely want to keep the weight reasonable. I will also be likely to spiral flute it.

Given the above - I’ve been looking at an ACE #3 contour but wasn’t sure if I was better to bump down to a #1 or #2 sporter?

#1 is the lightest option and is a touch below the min dimension to thread to 5/8" if you cut to 18". Could be done if you add a shouldering ring.

#2 works, and could be fluted, but the flutes will only be in a 10" long section of barrel and probably not going to get you lighter than a #1.

#3 is the heavier version of #2.

All depends on what you want for final weight.

This is the context I needed - thank you!

Any chance you'd know the weights of a #3 22" fluted?

I don't know why barrel makers don't have a Suppressor Contour.

Because, just get a carbon instead for $350 more bro. They look so cool.

Pay 1.33 x price of steel barrel which can be lighter than a Carbon barrel.

And need to open up the barrel channel as well. #nope

I have a DD Lti on a 24" Bartlein #3 that's .700 at the muzzle and 5/8 threads. When this barrel is shot I have an Ace #3 in the safe which will also be threaded 5/8 for the Lti.
The only thing I did was dust off about .015" from the face of the Lti mount to get rid of most of the internal chamfer. That gave me face contact from about .630 out to the .700 max dia.

Sorry for the delay. Depends on brand, but a #3 Shilen with 5 flutes will be around 2lbs 10 oz chambered in 7mm RM.

Tikka lite contour, have it threaded 9/16 and get a 9/16 direct thread for the enticer

If you Absolutely hate 9/16 or buying another hub direct thread then have a smith thread your barrel 1/2 then mount a permanent 5/8 adapter on it

Thanks!
