22 LR cz457 barrels

[600-60x]

Looking at barrels for my 457
L31 has one with a wasp chamber ?
How are the wasp chamber demolitions different than the standard chamber

Apparently the Wasp chamber has a 1.5 deg leade angle.

The otherwise similar SAAMI Match chamber has a 5 deg angle.

I hear a few reports that some skilled gunsmiths have lapped CZ barrels, with a taper at the muzzle, with good results.

I hope there not being shot in sanctioned ARA factory class as that is not allowed. no lapping is allowed; this came from Dawn and Brandon.
Quote, only recrowning is allowed for work on the barrel.

I have a L3I barrel in my 457. Wasp chamber. I can extract live rounds. It is very ammo insensitive. Sits in an Ultradyne chassis. 4 oz trigger using a Glock safety plunger spring.

Of course not. Silly to even consider such a thing. Because it would be so easy to tell if a barrel had been lapped. Wouldn't it?

Well hopefully shooters who do shoot ARA have a conscious and wouldn't think of doing that.
question would be would any respectable gunsmith lap a barrel knowing it would be used in sanctioned ARA
I like to think we have better people than that among the RFBR crowd those especially who shoot ARA

Yeah, they would. One gunsmith (not Calfee) offered to do it for me just for kicks, but I don't shoot factory. However, I do know people who do shoot factory and lapping is apparently fairly widespread. ARA shooters are just people and don't take an oath of honor. But now, if you shoot factory, you have to sign something saying your rifle complies with all rules or something like that. That should do it.

Why do I get the feeling that competition shooting is SO akin to NASCAR?

It's only cheating if you can prove it.

Nice.

Winner might be the slickest cheater. Not the best shooter.

Yet another 'sport' devoid of integrity. And I'm the fool for thinking otherwise.

People are just simply nasty as a whole.

You can pick up brass from a competitor --look at it and see if maybe they are using a modified firing pin--which is illegal simple to do---you can casually look and see if the breech has been worked indicating a possible set back and rechambering but short of causing a stink and whipping out a bore scope to check--lapping is not detectable from the outside by just being observant
I say all this as there is no great way to protest --you can-- I guess but after that you are "That guy"
So while you may suspect a rifle has been lapped, has rubber under the barrel etc etc and otherwise worked --it seems best practice to me - is -to try and whip their azz with your legal rifle and go on with it. There is no $$ payed--no glory except right there with your fellow shooters--and in that-- a win last until the parking lot clears --after that you are back to zero again so......I say at the nationals they should spot check ( they may I have never been ) and at least pose the threat of being caught--like check the first three finishers or some such. But..at a local match I say work on your game--whip em when you can--and just work on yourself.
I raced cars for 3o years--I am very used to being cheated out of a win. Shooting sports has proven to be Much more civilized than auto racing as far as that goes--hey if we are shooting for $1K I will protest my brother but the way it is now --smile and whip em when you can and keep rolling.

Disclaimer--I like all the guys I shoot with--if I do not win I figure it is on me

 

[wsmallwood]

I have not been an eye witness to any lapping or other illegal modifications to factory class rifles. I'm just going on what shooters (ARA included) have told me about thier own rifles. So, let's say it is a widespread practice. Then if you want to compete at a high level you about need to do that too. Let's say it's not a widespread practice, then what would a lot of people do if they believed it to be widespread. It snowballs from there.

It's something that somebody could do to a factory rifle just to make it shoot better. Just allow it and let the shooter decide.

Not all competitive shooting, just those competions with a lot of rules. The more rules, the more room to manipulate. That's why I shoot unlimited in ARA or Heavy Outlaw in ABRA. Not a great deal of room to manipulate the rules, at least in relation to equipment.

So. You just confirmed my suspicions.

Thanks.

My thoughts exactly.
I shoot UL so not a problem for me. but I see new shooters who buy their rifles from LGS who come to matches thinking, finally a class I can compete in and get hammered. how long do you think those shooters will stay?

I agree allow to make changes, but something not requiring a skill above simple hand tools.

Just wanting to know.
Does lapping make that much difference in a factory barrel?
What if a guy lapped his barrel but didn't get a good lot of ammo to shoot
and couldn't read the wind,
compared to a guy with a non-lapped barrel and a great shooting lot of ammo
and could read the wind better.
Very few people would know how to properly lap a barrel, and why waste it
on a factory barrel.

 

[tmwinds]

How would anyone verify that a barrel has been lapped?

 

[Jerry Halcomb]

This is typical evolution of sport. Unlimited class was originally born from competition with factory rifles. When they were modified and started winning unlimited was born. Today’s factory class was created to recreate the origins of .22 lr competition. That’s like time travel, it’s not gonna happen. This is a generation clamoring for the level playing field that has gone on forever. The level playing field ironically is anything goes and is only limited by how much money you want to spend!!

Could you tell me where in the rule book for this is written as I can't find anything about modifying the firing pin.
