Re: Suppressed .308 load with 175 gr SMKs
There's no difference when working up a load for use with a suppressor or not - varget and the 175smk must be one of the most written about loading combinations on this forum, search the reloading depot at the top of the forum page. 41 - 43.5 grains should be in the ballpark.
Good job you are not looking to go subsonic with this combination, I'm pretty sure that will lead to ignition due to under loading. Subsonics require powders such as Trial Boss to work effectively and safely.
