Tight Barrel?

[GLC]

I acquired an old Sako AV which had been re-barreled in .260 Rem. I have no knowledge of the rifle before I got it in Feb. 2012.

The rifle seems to shoot well. It will shoot 1" groups at 100 yds with consistency - I am not a great marksman, and I have only fired about 50 rounds through it. With work, it (not me) may be a really good shooter.

My question is the following: It takes a lot of effort to push a 6.5mm phosphor bronze brush through the bore. So, I have taken to using a .25 brush, and this works a lot better. Is it common for some barrels to be very tight? I don't have enough experience with center-fire rifles to know.

Thanks for your help. George

If it were me I wouldn't use a bronze brush. I would use a nylon brush and a good solvent.

The correct size brush is going to be tight. That's normal.

Are you using a bore guide?

Yes. I am using a Mike Lucas bore guide.

Re: Tight Barrel?

good solvent and patches are all you really need.

The smaller the caliber the shorter the bristles are and the more resistance you'll get. Use a good solvent and keep it clean. After cleaning apply a light coat of oil in the bore to act as a lube for the first round.
