Reply To: thimbles for barrels and do they work
aa I am glad to see you started this thread. I learned about indexing 40 + yrs ago, when my gunsmithing bud was setting up my 6.5mm long range (500-1000 yard) rifle. I had no idea that this technique was being applied to air rifles. It did make a major difference in my rifle back then. I know there will be the experts wannbee or real who say it does not make a difference. I personally would disagree. I cannot see any air rifle company going to the expense or using the type materials it takes to even make a bbl that is 1/1000 true even 3/1000 which is rather rare even with the top dollar pb rifles. I am getting ready to purchase a rifle for FT competition and would like to know of a source to get a thimble installed on it.
