[QUOTE="johnnyk, post: 284150, member: 307"] Ryan, I'm guessing your rifle is still pretty new. Give the barrel a chance to season. Give it a good break-in/cleaning routine. The first .300 WM Sendero that I owned shot about like yours is doing. I probably ran around 100 rds through it before it started coming around. I was starting to worry because I already had a Sendero in 7mmRM that was shooting lights out. I couldn't understand why this one wouldn't shoot. Some barrels take longer to come around than others. The .300WM that I currently have shoots great with 180gn Ballistic Tips and 69.0gn H4350 (.3's). It wasn't the fastest load but was the most accurate with this powder. I then tried RL22 with the same bullet and it wouldn't group for crap. I tried from 73.0 up to 76.0gn and accuracy never got better than .675". My stepson gave me a box of 180gn SMK's for my anniversary and with 75.5gn's of RL22/9.5M they shoot in the .3's. I shot five rounds today and velocities were 3121/3123/3124/3132/3163 (avg.3133). I pretty much run all my bullets for all my rifles .010" off the LaG's, unless it's a VLD type or just too short to touch. I usually play around with the powder charge or type (burn rate) until I find one that vibrates the right way everytime :) Hang in there man, it will get better. JohnnyK. [/QUOTE]
