As I mentioned in my post, I am sure they do have there up side. However, I don't think there neccesary if using the correct custom action. Like I said, I think it's the gunsmiths responsibility to be honest with the customer and let them know if a barrel block is neccesary. As I mentioned, if your using a large diameter custom action, like Nesika or BAT, you wont need a barrel block.
I wanted to make this post, because I've heard so many stories about guys getting talked into barrel blocks, and they were not neccesary. Make sure you do your homework when building a custom rifle
, espicially the first timer. I admit, I would have easly been talked into a barrel block during my first custom rifle
build. However, I had a very honest and well known gunsmith who informed me I did not need one if I was using a Large Diameter Nesika or BAT action. This gunsmith gave me valuable info during my first custom rifle build. I have learned a bunch since that time, and I want to make sure the first timer gets this info too.
Nesika and BAT informed me there large diameter actions would have no problem handling large diamter barrels without barrel blocks. If you think I am making this up, just give them a call, and they will tell you the same thing they told me. Nesika and BAT make there large diameter actions for this exact reason. However, if your going to use a 40" or longer barrel, then you might want to see if a barrel block would be benificial.
I just think there are a lot of gunsmiths out there trying to get people to spend money on equipment that is not needed. I have been swindled by a gunsmith before, so I know it happens. It is a long story, but I got taken for alot of money, because I did not know what to look for. I DO NOW!!
