This may not be the answer your looking for but i use a .284 dia. jag for my .308's. The .308 jag is way to hard to push down the bore unless its clean and dry then it will go down. If its the least bit dirty its like trying to push a car...
Hope this helped,
Nathan.
Thanks for the info Guys !
nddodd, did you write down the caliber diameter, what you use, or did you in fact measure the phisical diameter. Just asking, because you mentioned .308 jag, which has obviously smaller diameter than .308", otherwise you could push it in at all.
I want to make one myself, cause the jags I could buy online from the states have imperial thread, and my cleaning rod has metric thread. Anyway which one is better in your opinion, the slotted one or the one with the spear tip?
