I've recently bought a RSM Titanium moderator for my Tikka T3 .300Wm.
It has a 'pepperpot' style integrated muzzle brake, which can be unscrewed and changed for a different size that is calibre specific for the rifle up to .30 cal.
I used it on my rifle at Kingsbury 600 yd range this week and bullseyed the target, what a difference it makes. There is very little noise, more of a gaseous 'whoosh' than a loud bang, obviously the supersonic 'crack' of the bullet is still heard, there is much less felt recoil and muzzle flip. Far more pleasant to shoot with than the anti social muzzle breaks that some of the other shooters were using.
The RSM was made to order and is 145mm long, 45mm in diameter and only weighs 360gr or 12.7 oz in old money and at only £375, is almost half the price of another Uk manufactured Titanium mod and about the same cost as an Ase Utra.
In theory I could just buy extra pepperpots to suit each thread and calibre of my other rifles and it will work on them all.
Money well spent.
