is this normal wear for a moderator

[beesley121]

Well this is a brand new rifle and it's not been out much, prob less than 10 times but I like to paper punch.

 

I clean it after each outing and it's left on the radiator to dry. This is because my rifle is still bleeding in so that too is clean after every outing.

 

So that make it even worse that it deteriorated already

 

I've read there a warranty on these sak, is that true

[jeffo223]

Yes there is a warranty on the moderator, I think Jacksonrrifles will charge you 60% less of the normal costs but what's the point if it's just going to burn out again. Get a moderator that is made for 17hmr not something that is made for 22lr and seems to be ok with 17hmr because that obviously don't work....SAK? Sack that!

I suspect its single shots v range use. With each shot the metals retain heat and the next rises the temp still further. I never cleaned my SAK on the HMR I had either and it was fine after in excess of that

[Dougy]

I mentioned years ago about this and I think it got poo poo,d. Exchange it for an ASE utra.

Sak on a lr ok.

[jimmygillborn]

the damage that has been caused, what it result in doing ie irregular shot placement etc?

[dorianbuilders]

I thought we were discussing the fashion sense of the moderators here.

[Dekers]

And some say a SAK is fine for Hornet!

 

The manufacturers say it is OK for Hornet on their website, if you have a problem with that talk to the manufacturers!

[Dekers]

Obviously a lot of different views on the SAK here, the fact is Jacksons give it a lifetime replacement warranty (see their website) and also rate it at 10,000 rounds on a HMR.

 

My Sirocco melted after about 2000 rounds on my HMR, things happen, my SAK on my .22WMR (more energy) is about 4000 rounds down the line, used almost exclusively with Hornady 30 g V-Max at 2200 ft sec and 320 ft lb and looks like new internally!

I think barrel length can play a significant part. My 14 inch Anschutz chewed up a sak after only a few hundred rounds.

 

Perhaps people stating whether their sak is chewed up or not could give their barrel length.

[team tractor]

600 in with 16" barrel and all good

[Bewsher500]

its not knackered unless it is not making the shot quieter, is catching bullets or is altering the POI

 

it just wont be as effective as the holes get bigger

but as the gas cutting is predominantly going to be the nearest baffle hole you wont see a major drop in noise attenuation until the cutting moves up towards the last baffle

 

for £35 you should treat them as disposable anyway

 

if you want to protect against gas cutting you need stainless and it comes at a cost and weight

 

stop opening it to look at the hole and replace when it either gets a lot louder or affects accuracy

Ah, sense at last !

[wacker]

That's some gas cutting! Shoot it until it falls apart then get a LEI

[turbo33]

Not sure I would like to be firing an HMR round into a can full of shrapnel and possible obstructions 20" from my mug

[Catweazle]

Are we all looking at the same picture ? The hole is oval because it is cut into an angled face, and the part that looks like a jagged edge is actually part of a baffle behind the hole. Metal that goes to such a sharp edge is going to get bent over or eroded, but the moderator looks safe to me, no case of " firing HMR into a mod full of shrapnel".
