Barrel speed up after rechàmbered?

[JayBeeYou]

Question for anyone who may have had this situation before. I had a Bartlein barrel 11 1/4 twist that I ran 600 rounds through. It was impressively accurate with 185 juggernauts, but I went up to the 200's and could not get the vertical to go away at LR. So I pulled the barrel and went to a 10 twist krieger.
I sold the barrel to a friend cheap and he is now chambering for his rifle. My question is after 600 RDS will the barrel go through a speed up between 80-120 RDS or not?
I would not think it would but just seeing if any first hand experience.

Thanks

Why don’t you ask your gunsmith,I have a feeling he would know.

From my experience the Barrels I have set back and rechambered did not speed up like a new barrel. However, since I almost always go with a new barrel, my experience with setbacks and rechambering is only 2.

New owner'll be using the same loads you used? I'd say no, I doubt it'll be any faster.
If he's doing something different - like a different propellant, different chamber / throat length, tighter throat - then yes he just might get more velocity than you saw.

Thank you sir,
That is what I expected but was just looking for some real world experience with it.
