How well will this work? I'm in the process of ordering a Sako brake for my TRG-42 in 338LM and am curious if it will be equally effective on my T3 Tac in 308w aswell so I can just switch between the rifles, instead of ordering one more in 308w for the T3 Tac. Also, is there even a difference between the Sako brakes for 338LM and 308w or are they identical parts?
