I am wanting to put together a 6.5X47 lapua. I am wanting to use a Savage target action. I want a RH bolt / Port. Is a Standard Caliber bolt head Target action SKU#18184 what I need to buy? Why is there not a long and short action in the target action? Is it because it is single shot and no Magazine? If so I could use it for a short or long action calibers?
