Moderators/"suppressors"

hurlsey

Just a general wondering, why do lads use Moderators on rifles with high velocity ammunition?? This more or less defeats the purpose of a Moderator in the true sense unless its used with subsonic ammunition!!

A) it reduces velocity
that affects range/accuracy
C) wears the internal parts of the moderator due to high pressures

IMO using a Moderator without havin access to subsonic ammunition is defeating the purpose

Any thoughts?

* it should be noted I am not attacking there use or those who employ them I'm just wondering why?!

Safety, don't have to wear hearing protection (good for your ears on its own, a 20dB reduction is still very welcome) Without hearing protection a person can give and receive instructions/warnings/advice from those around them.

Recoil reduction, it makes the firearms more comfortable to shoot (which sometimes will have a positive influence on shooter and allow them to shoot better groups), allows for quicker follow up shots if necessary.

Also on point A) some people are of the opinion they increase velocity. Either way for hunting applications they don't have a big enough effect on velocity or range to worry about.

If I was target shooting competitively on a range I wouldn't use one as it's just another component to worry about/fiddle with. For hunting and varminting they are a very useful and valuable tool.

The only negatives I have with them is they are not lieftime products, they do wear out (know that when buying them though) and the extra weight on the end of a barrel is not great for firearm balance.

A) it doesn't
can act in the same way a brake does thereby increasing accuracy and assisting in follow through
C)obviously anything that gets used gets worn, the same could be said for the rifle

It's quite simple. It can improve accuracy and allows you to shoot in situation where hearing protection is a last recourse.

If your coming at this from a ninja assassin point of view then yes, a mod without subsonic ammo is likely to get you killed before your buddies on seal team 6 can extract you

4200fps

Only two disadvantages I know in using a mod is increased weight and adds extra length to your rifle. The rest is advantages

One shot on kill

Are you taking about rim fire or center fire. As far as I know the ammo doesn't have to be subsonic for the mod to work properly.

I ask this as I only have a mod on my 22. Don't have one for the center fire yet.

A]Nope,reduces the supersonic crack not velocity.
B] Nope, should have no effect on range or accruacy,bar compensating for extra front end weight,[you can trim the barrel if it is that much of an annoyance]or the bullet is hitting an internal baffle.
C]Anything will wear out eventually,but firing normal ammo thru it wont make much difference.Unless you ar firing it on something full auto.Even then a well made can will withstand nowadays over 100k worth of rounds before it is unserviceable.

A) it reduces velocity.....No it doesnt
that affects range/accuracy..no it doesnt.good cans fitted correctly dont affect accuracy,they may have a repeatable poi shift for your zero which can be recorded and accounted for.this is usually very small.How would it affect range ?
C) wears the internal parts of the moderator due to high pressures...no it doesnt.quality suppressors and practically all centre fire suppressors are designed for use with high velocity ammo.everything on the planet wears with use.

Reasons for their use have allready been listed by others.biggest pro for me is makin my centrefire ear safe without needing earpro

Not really, what you hear with a mod is the supersonic crack. This is constant regardless if whether or not you use a mod. What a mod does reduce is the sound from the gas expansion from the shot. The can acts like an expansion chamber.

Recently started to use one on a .243 with 100grn, have to say I'm hooked, Damn the expense, I'm getting one.
In the field it just makes the rifle so much more tame. Although slightly off balance when slung for the carry the rifle still points and shoots as it did prior to fitting.
Ballisticly the foxs don't notice any difference.

I fired one round in all my years without a moderator on my .223 and theres a reason I only fired one round. It near blew the ears off me.
A moderator is not a 'silencer' so I disagree that its pointless use one without sub sonic ammo. It stops you going deaf and I wouldnt shoot without one.

As far as I know. It catchs the gas and reduces the speed the gas leaves the barrel. Is that right.

The only time a mod will effect the velocity if it is a internally suppressed rifle with a ported barrel..

It also makes it difficult for an animal to hear where the shot originated.
If you shoot at an animal and it hears the crack but not the bang, its very hard to locate you .
If you miss this sometimes allows you to get a second shot before the animal decides which way its going to go.

Basically the silencer, sound modifier,moderator ,suppressor is semantics for the same thing.A device that significantly reduces gunfire noise.

Cannot add anything that has not already been said, but here is a video posted a few days ago. See the difference in recoil management with and without a mod.

From someone that used to shoot a 30-06 (close enough to 300 winmag) trust me it's a necessity.

4200fps

Any round firing greater than 1125fps will break the sound barrier. I personally think air pressure and wind speed has some impact on how loud the supersonic pitch noise is going to be after the moderator absorbs the crack/boom out of the round. This also depends on the quality and build of the mod of coarse. Just my opinion
