.22lr moderator

[Oly]

I'm thinking about moderating my .22lr Anschutz 64MPR (heavy weight barrel) for quieter rabbit shooting.

 

I would like to know the pro's and con's for this desicion - including any possible negative effects on accuracy & the noticeable benefits when rabbitting (do they take much notice anyway??!).

 

Finally I would like to know recommendations for manufacturers etc - I'm particularly keen to hear about moderators that are the same diameter as my heavyweight barrel too.

 

As ever, thanks in advance!

there are really very few cons, the only con is the extra weight and length, however with a 16" barrel (you dont need a longer one) you can easily keep a moderated .22 barrel with silencer under 20" (less than some factory barrels) Weight also becomes less of an issue once you remove the leverage of a long barrel.

 

The only possible effects on accuracy might be if your gun was poorly crowned after being cut down, or if the thread was not true and some clipping occured in the silencer, the simple answer to this is to get a good gunsmith to do the work, not a friend with a lathe.

 

The advantages are that you dont make such an obvious disruption to everythign around you, although in my experiance my bags have not changed since having a silencer installed, the rabbits are still aware of you taking shots. But they are less edgey after the 2nd or 3rd shots when using a silencer.

 

Silencers which are likely to roughly match the profile of your barrel are probably the Parker Hale. I use this, its not the best one, but it does the job. The SAK looks more bulky but weighs less and is more effective. The ASE is the really pick of the bunch, but twice the price of the parkerhale or SAK.

Depending if you want an easy cleaning one then I would get one of these:

 

 

Silent, made of aluminium and plastic baffels so it aint heavy.

Once you've got one, you'll see (or hear) the pro's, it's well worth moderating a 22rf. There should be no loss of accuracy either.

 

Models I've tried;

Soundbiter -Very short, very light (made of plastic!), tough

Sak -Quite chunky, seemed very quiet

Parker-Hale -matches barrel profile of my cut down finnfire

 

All are about £20-£35 depending on proof.

a moderator on a .22rf is highly advisable, they reduce the noise to next to nothing. brilliant for rabbiting, the only con is the extra length, but thats no big deal...

[markbivvy]

cant think of a reason not to have one on a .22 rimmi.

It's pointless shooting subs without one, but for hypersonics you may as well not bother.

i have a SAK's on my sako finfire and its very good indeed. a bit thicker than the barrel but does not look offensive or out of size

[luckytrigger]

Ive got a sak on my sillouette and its quieter than my old rapid 7 airrifle. Cheap too

[invector]

I've got SAKs on both my .22 and .17HMR. Both are CZ Varmints.

I have a Parker hale, find it great on my CZ 452 .22lr.

Thanks for all the info so far - much appreciated. If I do decide on a moderator I'm looking at having my barrels shortened first - however my anschutz has fluted barrel end on it which I have been told by a friend that it acts as a choking type effect to aid accuracy - common with many "button" made barrels - comments??

 

Invector - any chance of a couple of pics of your Varmints with moderators attached?

 

Cheers,

i agree with that i would go for it.

Very happy with my Parker Hale too (CZ452)

The term button your friend is referring to is one of the three methods of rifleing which are button, broach and cut. Poorly rifled barrels using the button method can show a reversed choke effect which is detrimental to accuracy. This problem is more likely to occur in tapered barrels therefore your tapered fluted barrel will have, for want of a better term, a thicker end to the profile at the muzzle to stop this happening.

Charli,

 

So I presume from what your saying is that as they employ a thicker end on the barrel during the manufacturing process so that this restriction/choking does not occur - hence it is now effectively surplus to requirements (as it has done it's 'job') and could theoretically be removed to allow barrel shortening to take place?

 

I'm a little unsure to whether you've got the whole picture too as I don't believe it to be a tapered barrel...it is it is not noticeable to the naked eye! To my eye the barrel is uniform in it's length (i.e. no tapering) apart from the last 3 inches - at which point the barrel tapers slightly outwards to become marginally thicker than the rest of the barrel - the 64 MPR can be seen at http://jga.anschuetz-sport.com/pm/detailan...;project=jga_de

 

Thanks,

I miss read your post. Your first post did say heavy varmint barrel whereas I miss read your post where you mentioned fluting.

 

I am no engineer and others on here will give you a more educated answer. However, I believe that Anschuetz, being highly accurate rifles, have built in this "thicker end" to the barrel for exactly the purpose of very slightly introducing a constriction and therefore increasing accuracy which would compensate for any errors in the rifleing. I would think that removing this would be detrimental to accuracy and I would not go down that route without the express guidance of a top flight riflesmith or advice from the makers. Also Shortening this type of barrel could alter (releive) the stresses in the barrel steel caused during rifleing and thus alter the tolerances.

OK, thanks for that info. Any others got any comments on this one??

Yeah ive heard of barrels being made like that with there being a difference of .001 from the bore to the muzzle im not sure about the anshutz id give em a ring or see if anyone else has done it.

A guy I shoot with was saying last night that it is to do with how a button barrel is made - they are heated drilled and then a button pulled through it to finish the job. As the buttoning process is at such high pressures then metal is then left stressed (if you get it wrong it goes massively wrong apparently!). This stressed metal is basically what makes the barrel so accurate - unlike most other barrels which all the stress is taken out of the metal first, and then simply drilled. Hence he thinks that by cutting the barrel it has the possiblility of weakening and damaging, and has even heard of barrels virtually exploding apart as the barrel's stresses are released!

 

Any comments/other knowledge out there on this one?
