Free: Contests & Raffles.
Forgot to add I shoot a 1-9 twist with 52 gr. hollow points. Your existing barrel is probably just fine accuracy wise if you free float it and it will shoot M.O.A. at 100 yrds I would run it.
If your shooting M.O.A. at 100 yrds with what ya got your good to go.Dont go spending a ton of money until you KNOW this is going to be something your going to do a lot.I have seen a large number of people spend a ton of money getting all set up for calling coyotes to just end up losing interest when things did not come together for them right away. Calling coyotes is something you have to have a passion for, you have to live it,breath it, dream it and love it or you will end up quitting the game.There is one heck of a learning curve and it does not come easy. Save your money for gas and time of to travel to find good areas.This is the BEST thing i can tell you to do right now. Go with what ya got, Change only what needs to be changed ( for accuracy) then use your money to spend time in the field calling coyotes .
