I wish there was more stock options for these rifles.

I wonder how much it would cost have a blank from Mcmillan inletted.

@swavescatter have you measured any of your fired brass? I used a headspace comparator and my fired brass only grew .005-.0010. Wondered if the chamber was tight or just the thicker Norma brass didn’t move much after one firing

I’m only getting 2500 from a 20 inch tikka in 6.5 creed with handloaded 147s. What’s your load?

It was… crunchy. No pressure signs though but right at the edge. Also not a tikka so add a free hundred fps.

Only measured one of each.

Norma grew 1.5 thou
Hornady Match grew 3 thou
Hornady ELDX grew 1 thou

Just measured once fired Norma brass from my Fierce Reaper that had a verified FUBARd barrel and wouldn’t chamber factory Hornady.

Norma brass grew 2.5 thou in that

Man I gotta say I would be bummed if I jumped up to a heavier, harder kicking, PRC and loads came out at the same speed as they do my 18" Kimber 6.5 CM.
Guess hand loading the PRC is the way to go.

Well I chopped a couple inches off and added a suppressor - looks like I only lost about 35 fps muzzle velocity with the Norma.

I lost about 20 fps with 147gr ELD Match and 43 fps with the ELDX factory ammos. Swapped out scopes to my ATACR. Heavy little rig now...

How many inches did you cut off and were those numbers total fps lost or fps lost per inch removed?

About 2"but I didn't measure exactly, just in front of the flutes.

Total fps lost, not per inch, but I wasn't using my suppressor initially. So likely what you would expect apples to apples (25 fps/inch)...

Pretty good group, right? Top hole was last shot.

I'd say it's extremely promising, considering this was a load workup with N565 using Large and Magnum primers (156gr Berger EOL) all in one string...

Those are impressive groups from a factory rifle!

My son and I bought 3 of the s20’s. A 6.5 PRC, 30 06, and 300 win mag. My favorite of all of them may surprise you. It’s the 300 win! I put an Area 419 sidewinder muzzlebreak on it and it kicks less than the PRC. It also shoots super tight groups. My son shot a mtn goat with the 300 win at 240 yards and the goat dropped in his tracks!

The drop of the PRC at 400 yards with a 140ish grain bullet is 7” more than a 150 grain 300 win bullet. The PRC also travels approximately 400 fps slower at 400 yards.

I think you can see why I chose the 300 win vs PRC as my favorite!
