Moderator bore size ?

[Hales Smut]

Is it possible to use an A-Tec CMM4 in 30 cal on everything from 223 to 308/30-06 ? Any advice?

Yes, that is my preferred approach from a safety perspective. I only have .30 cal moderators. Regards JCS

I use a .25 (6.5mm bore) moderator on .243, .222, .22, and .17

for me the cost implications of more mocerators outweigh the possible, potential but unlikely difference in sound reduction buying a smaller calibre

So long as the bullet can pass through the hole and doesn't generate more energy than the largest calibre specified I don't think it matters. I have used a .30 mod on a .223 and the noise reduction wasn't noticeably different.

Hello HS.

Yes you can, although some will say that the moderator bore linked to the size of the bullet fires has better attenuation. Personally, on my .243, and .30-06, I use .30 Cal mods... The .243 is not much quieter with a .25 cal mod as I tried it, but did not get good accuracy, so went to a .30 cal Roedale, and things improved immediately. Not a scientific answer, but only my experience.

All the best.

Neil.

Yes, good idea cover all your calibres with it, dont listen to the crap about large calibre can, small calibre rifle, bigger bang, you cant measure it on the scale.

Yep that's what I do and it's a great moderator also....
