I had a low wall relined in .22 a year ago. Shooting 1230 fps plus or minus a little with great success. The other day I shot some high velocity 1650fps which seemed fine. Today I went back to work on a 200 meter target and couldn’t get on paper. I don’t have a bore scope but when looking down a clean barrel it almost seems like the rifling is gone. What happened? 

Lower fps Eley match, Aguila 1130 fps, Eley club and Winchester super X 1650 fps.

Aged. So best way to get it out? Thanks

I'd use some "Lead Away" cloth, or Birchwood Casey "Lead Remover" cloth. Make sure you have a very tight patch and push it through the bore. It will come out as shards of lead shaped like the rifling. Change patches each time until it comes out clean, and then polish the bore with the last patch by pushing it back and forth until it looks like new again.
I've used this on old bores that looked ruined, and when done they shot great.

Soak a patch in Kroil, give the barrel some stokes then set it aside. When you have some time, get another patch, soak it in Kroil, then wrap it with 4-0 steel wool, with some Kroil on it too. It’s going to be a tough start, so you will have probably have to bump the rod pretty good to get things started. The steel wool wont harm the barrel and will grab the lead. You may have to do the procedure a few times to get all of the debris out. When you think it’s gone, scrub the bore with Kroil and a tight fitting brush, then clean as usual. It works, and won’t harm a thing.

I’ll add this to “if” it’s a leading problem. On a soaked patch use artist turpentine. It is quite different than the Home Depot stuff. It’s not cheap but works very well at grabbing lead out of the bore. 
Amazon makes it easy if you search artist turpentine.

I don’t know. Curt Hardcastle did it for me and I took his recommendation. 
I tried a number of the suggestions like kroil oil, artist turpentine and others. Everything but shooter choice which came yesterday. I can’t say that I ever saw anything that I would recognize as lead or lead particles. 

So I went to the range today to shoot 50 and 100 yards. Tomorrow if they worked for 185 and 200. 
Shot CCI Mini Mag, 40 gr , copper plated @ 1235 FPS and Aguila 40 gr, lead, 1130 FPS. 
Both were perfect. Sight setting for Aguila a little less. 
Fingers crossed. 

I tried many of the suggestions like. Kroil oil, artist turpentine and others. All except Shooters Choice which came today. Nothing ever showed what I would think was lead. 
Went to the range today for 50 and 100. If things worked I’d go tomorrow for 185 and 200. 
Shot Aguila 40 gr, lead and 1230 FPS. and CCI 40 gr, copper plated, 1235 FPS. Both were great. A little less sight setting for the Aguila. So we’ll see what happens tomorrow.
Who made the liner I don’t know.
Kurt Hardcastle did it and I took his recommendation. 

If Kurt installed it, most likely a TJ’s liner.
You know, copper plated bullets leave copper fowling. There fine for hunting and plinking, but not so much for precision shooting unless you like to clean copper…..

The first place scope and iron both shot 95’s at 300yds. The top 9 places in scape class all shot on the 90’s. 
A couple used high velocity ammo and had lower scores especially at 300yds.
Blair Svihra won scope
Kim Hays won iron, Kim also had a higher score at 300yd than he did at 200yd.
I believe We used the MR 2  200yd target at 300yd.

Stick with standard velocity ammo for long range shooting. The ultra HV stuff loses velocity rapidly and becomes unstable in the transonic zone. [/quote]

I'm shooting the Norma Xtreme Long Range at 300 and 400 yards.

It has an average muzzle velocity of 1165 fps with a standard deviation of 7 according to my Garmin chronograph.

The same ammo at 300 yards.

At long range higher muzzle velocities result in less vertical spread.

At 400 yards with an MV of 1165 with a SD of 7.5 a two SD spread above and below the average MV the vertical spread due to this variation is 9.25 inches according to the "Analytics" ballistics solver from Bryan litz.

If the average  MV is reduced to 1065 fps the vertical spread increases to 14.01 inches.

It is true that the higher MV does result in more horizontal drift due to the wind.  At 1165 fps. a one mph change in wind speed from the right or left moves the bullet's impact 5.5 inches.  At 1065 fps. the sideways movement is 5.04 inches.

High velocity 22 Long Rifles bullets do not become unstable in the transonic zone as established by McCoy and several others.  This is a myth that is simply not true.
