Hi Zak, I have a 338BA on order. I plan on using this for 300 RUM, 308 and 260. I plan on using the 2 port brake on the 300 RUM, but was unsure about the 308/260. Other then the added weight, Any reason NOT to use the 2 port brake on smaller calibers? Any evidence to support that a 2 port brake on the 308/260 may help to reduce blast baffle erosion due to the extra brake port redirecting gasses? Thanks again.
