I picked the wrong gunsmith from the get go on my sendero. He would only take the trigger down to 3lbs, now some people think thats light enough, I like a light trigger and thats why I bought a jewell. Have you had a muzzle brake
put on it or are you too??? I had one I mine until we figured out it was built wrong and according to my new gunsmith was causing some of my accuracy issues and I can say after he took it off it did shoot better, but now because of back surgery I have to have another brake put back on, also some will say you might have a flinching problem, those 300RUM's do have a little bit of recoil to them. Are you a reloader????
When you get that sendero dialed in you will have fun with it and will soon be shooting out to 1000 yards.
