Yay for no longer heat soaking the barrel after 4 shots!

Beautiful Rifle.

I'm curious about your crown covers. Is this an involved process?

I work at a company that designs and manufactures aerospace parts, the cutters/roughers/end mills that CNC's use get dipped into a heated vat of plastic like rubber when stored to protect the edges.
I just made solid pieces of round that were the size of my muzzles and dipped them.

Thanks for the detailed explanation, that's a great idea.

1.2" diameter to 1" dia muzzle

My that's a big one. You are going to need double hernia surgery after you build that one, that's rail gun size.

Thank you, no problem.
I've notice the one I've had on my .308 McGowen barrel for almost a year is pretty beat up - and it's always snug on the end of my barrel when I'm not shooting - so to think that same sort of wear could have been done to the muzzle/crown encouraged me to make more.

Curious why you went so long? The 6.5x55 isn't really a big powder burner like a belted magnum. I have a McGowen in 243 that shoots less than 0.25" groups.

You are going to have a sweet shooter when its done!

Actually, among modern action hand loaders, 28 29 and even 30 inches isn't uncommon in this cartridge when doing distance work. Especially since I'm using a slow burning powder like rl22.

Longer barrels are better for long distance: more muzzle velocity.

Yeah, not inherently more accurate just because it's longer - simply aids in bucking wind and reaching out to the long stuff.

Exactly. Regardless of length, barrels are bored straight not crooked. Unless there is a manufacturing error, of course.

Truly straight barrels are very uncommon.

I know McGowan makes Savage pre-fit barrels, when you say "pre-fit" for a Remington, is it short chambered or how is headspace controlled?

All I know is that it's finish chambered and doesn't require reaming

So, in theory, anyone with a barrel vice, action wrench & headspace gauge should be able to screw this on and go shoot...?


Randall- I'm not a gunsmith & don't pretend to be. I'm asking because I don't know the answer. You've done up a bunch of Remington's, how does the headspace compare from one action to the next? Recoil lug thickness would probably make a difference too, wouldn't it? Is it ever the same? Just trying to see the whole picture. Thanks.

Hmm, well did they supply a recoil lug with it as well? I think you will be extremely lucky if it headspaces correctly without modification.

I have done several rem700 barrel swaps of factory barrels that would headspace within Saami standards by just unscrewing one barrel and screwing in another.
I usually ended up tightening the headspace some though by surface grinding the lug a couple thousandths.

Keep in mind that Remington barrels are mass produced and just screwed together so they are maintaining tight enough tolerances for guns to interchange parts without issue.

What are you saying?

What are you saying?

What he is saying is that even high end barrel blanks are not straight. I have chambered a bunch of barrels than even through the breech end is dialed into .0001" , you look at the muzzle hanging out the spindle and you can watch it moving. It's normal and doesn't affect accuracy. Typically you want to time it facing up so that it doesn't affect your wind age adjustments and gives you slightly more elevation range.

Watch this video, typical production rifle barrel. You'll see how far off it really is.

I don't do barrel channel inletting.
That's why I ask people to walk-in with their barreled action...

^^ Holy smokes!!!!! You will have hernia surgury!!!

My *guess* is the headspace can be set by bumping the shoulder.

I'd start out with WAY coarser sandpaper than that... 60 or 40 even better if you can find it.

As to the barrel protectors.... A lot of woodworking tools and machinist endmills come coated with it. A blade sharpening service uses it too. I've not looked for it, but you can probably find it at woodworking supply places like 'rockler'. Or you could go to a hardware store and try using 'plasti dip' instead. If you do, get the liquid not the spray cans.

Well, I'm only lifting it out of the case to put on the ground then lifting it again into the case - not doing any run and gun tactical stuff, so I should be alright.

I used 100 grit then 180 220 and 500 to finish - seemed to work fine, just takes some muscle.
Opened most of it up to 1.25"
