I am stuck on what bucking to get. 1. Nineball Purple Wide-Use 2. Firefly Hard 3. PDI W Hold (Will this be able to handle an m170?) My bar 10 can shoot 250 feet with the stock barrel and teflon bucking mod using an m170 and .4g. I want a 300 ft effective range. I have not gotten a tightbore yet, but I will. I only want to ask which bucking is best for a flat type adjustment lever and the components I listed above. I know about R hops and flat hops. I just want to know which of the following I listed above will best help achieve the 300 ft goal with respect to my circumstances. Also, if the answer happens to be PDI W Hold, I want to know how long that'll last before being worn by the M170. Thanks.
