10 inch 22lr Contender Question
« on: March 29, 2011, 05:02:49 AM »
Hey guys I have a 10 in 22lr factory barrel one of the old ones that has no crown. I it one of the barrels that the end of the barrel is flat with no crown. My question is do any of you guys have one like this? And how does it shoot? I wonder if I got it recrowned (or crowned at all) if it would be more accurate?

Unless your barrel has been shortened and left raw from the cut by some nimrod your barrel does have a crown pard.   Regardless of whether the barrels muzzle is a so called flat, extruded or inverted style, the crown is not the profile of the barrels "muzzle" (profiles are only meant to protect the crown, and sometimes for assetic appeal).   Instead the "chamfer" on the terminal end of the bore and rifling is the crown.    No doubt a flat muzzle profile deosn't protect the crown itself as well as the others do.    But as long as the crown itself is crisp and even all around the bore with no damage (burrs, nicks, etc) the barrels accuracy will be fine.   Some crowns lend themselves to more consistent accuracy, ie so called target crowns that use say 11 degress chamfers with invereted style profiles commonly, but overall it comes down to the condition of the crown itself regardless.   A simple check of a crowns condition can be made after shooting the barrel enough for a "powder star" to form on the end of a muzzle around the bore.   If its even all the way around the bore the crown is usually fine.    Far more crowns are damaged by poor cleaning techniques and highly questionable cleaning tools than from mishaps using the firearm.   It's not too hard to restore a crown that is not badly damaged yourself, but most will opt to let a qualified smith do it.

If in doubt, have it recrowned... it doesn't cost that much.

I received  10 inch 22lr TC barrel during a trade back a while ago. Mine didnt have a highly visible crown either. Accuracy wise, it wasn't the best, but then I really wasn't interested in 22lr anyways so I didnt try to hard to maybe find the right ammo that suited it.
I have some friends that shoot small bore silhouette competitions, they say that the TC match barrel is quite a bit more accurate then the standard.

Thats the way mine is. The end of the barrel is flat with a hole where the bullet comes out. No crown I have tried 3 or 4 different kinds of ammo and the best I can get is about 3/4 to 1 inch at 25 yards. The bore looks fine so thats why I was wondering about getting it crowned if that would help.

I would keep trying different ammo before I got it recrowned.  Try some different bullet weights,  different velocities, and some match loads.  I have over a dozen different boxes of .22's and I usually try them all with a new barrel.   You never know if you will find the sweet load.

Even if you eventually have to get it recrowned,  its not a waste.  Just start over to find the right load.


Also,  I agree more .22 barrels are ruined by improper cleaning.  In general, I clean my new .22 barrels once then NEVER touch them again.  Modern 22's are lubed or waxed and are self cleaning, will coat the barrel and not rust under normal use.   If I start to feel guilty (after many THOUSANDS rounds)  a quick brushing with solvent is all it takes.  Many target shooters rarely clean their barrels with a brush and if they do will shoot hundreds of rounds to "season" the bore before a match.

Rescue, Your group size was about what I was getting out of mine. I also didnt think it was all that great also. Especially when I had a Ruger Charger, that also had a 10 inch barrel, and compared side to side? The Ruger was much more accurate.
I wasn't impressed at all with the standard 22 lr barrel.
Now my 357 and 222 rem barrel are very accurate, so its not me.
I dont what kind of accuracy your looking for?

The Winchester M52C  .22 target rifle came with no crown. It was highly regarded as one of the most accurate factory rifles at the time. I have one. It does not have a crown. With the right ammo and no wind, I have shot 2" 5 shot groups off a rest @200+ yds.

     I had a 10" 22lr barrel with a rounded crown, an older bull barrel.  It shot great with open sights, for what it was.   I scoped a 22 lr match barrel with a rifle scope for NRA Hunter's Pistol.  It really isn't the crown that affects accuracy,  the ammunition does have more to do with it.

      In the usual ammo, Federal Lightning (now Gold) or Winchester Super X was about the same.  Accuracy is good, not fantastic.  I tried some variations at 75 meters and they all bombed!  Winchester Wildcat (white box), Subsonics (green box) etc.... all were worse. Anything under 40 grain roundnose in weight, didn't carry to 100 meters! 

       Now I use three kinds: Winchester X22LR, CCI standard velocity and CCI Green Tag.  The CCI Standard Velocity will work if you can adjust your sights for it.  There isn't a firearm that doesn't like the consistency of Green Tag but, sometimes the wax is too thick on the bullet. 

        If (and this is a big if) you happen upon PMC Sidewinders in 40 grain, it's probably one of the most accurate to shoot.  Runs right along with Green Tag.

       Never mind Velocitor or value paks, that's for kids.  

     Thought the scope was off, nope, one shot in the quarter spot at 50 meters!  That's my best friend there.  Super X 40 grains
