Right. So even if you had an advanced cool propellant, moly coated bullets, and a fancy chrome hammer forged barrel, it would still be the rate of fire which could cause problems?

I've seen some bad things happen with Nitride barrels, that being said only SS not Chrome moly.
If I was gonna do nitride it would be chrome moly and after it had about 15 rounds down making sure and very fine tooling marks are gone in the throat from the reamer. Once its nitrided whatever in the barrel before will be after. |

My first choice would be the new 400 steel that Bartlein is using now I gotta believe other manufacturers will start soon also.
I dont think Bartlein is making 20 cals unfortunately. |

What are you seeing with the nitrided barrels?

Bore and grooves dimension changes, like I said ive never seen it on a chrome moly.

I am shooting a 20 Dasher with 55gr Bergers, and it's a Bartlein gain twist barrel. It is very accurate but as others said I don't expect much life out of it. I only shoot it maybe once a year though so it'll last me forever. I would like to try some heavier bullets but given how little I shoot anymore I am satisfied where it is now.

Bartlien doesn't list 20 cals on there website, maybe worth a call though.

i have a 20 br in a rem 700 titanium , shot in the .3 with 32 and 40's first couple loads. i never heat the barrel up as i use a timer and wait 3 min between shots. rifle is 20 years old and has less than 50 rounds thru it. 40 rounds load work up and 10 coyotes which is what it was built for.
had several pairs of coyotes called in and would shoot one and the other would head for the next county. i would start barking like a dog or hit the old coyote in distress sound. they would stop at 350 to 400 yards, the 20 br would reach out and do it's job.

Dave i wish somebody would try a barrel in the new 400 Bartlien steel in a 20 Dasher, 20 BRAI or 20-250 if nothing more to test how many rounds compared to there regular steel.
