As I posted earlier, I just ordered an X-Caliber pre-fit barrel 6.5X55 SE. They told me that the reamer they use will have .266" of free bore, which the guy from X-Caliber said is not a lot of free bore. I ordered a 1:8" twist 5R barrel and I'll be shooting 140-147 gr high BC bullets.

Is .266" about the right amount of free bore?

Will .266" allow me to load theses bullets out to the lands?

Looks like it is less than this version (but that's a 170 gr cast bullet!). I'd say you're gold.

You should be able to get there... My 260 Rem Match CBI barrel has a .190 freebore. I shoot the 143 ELD-X out of mine with a COAL of 2.933 which is .04 off my lands. you'll have .076 more room.

The saami creedmoor is .188 I believe. If they are measuring it the same way, .266 is more than I want. Somebody setting up for the new 150SMK bullets (in a 6.5x284) is going for .200.... I have read some swede reamers are setup for the massive 160g roundnose bullet for hunting in the old days. I wish I could be of more help,

Don't tell the guys using the Norma 156 gr Onyx in their 6.5X55mm they are out of touch. ;-) They won't share any moose kielbasa with you.

No doubt they work. Thanks for sharing the reamer print, it will help me read some of my own.

Those guys are real sharp. I'd imagine it will be right.

I've measured freebore on a couple of my other rifles (257 Rob and 300 WM) and they are running about +/- .200", .266" seems like a lot of freebore. I hope I'll be able to reach the lands with 143 gr ELD-X with enough neck to hold the bullet in place.
