Some of my possible shots are 1500yrd possible and never owned a rifle with this capability. Looking at upgrade on barrel down the road. Is shillen a good way to go? I'm a newby to this gun and long range. Go easy and thanks for taking the time on combinations. lost in wyoming and lovin it!
Welcome. Im' not sure of the twist rate on the factory Sendero but as a rule I wouldn't shoot anything unde 160gr and would look to the 180-190gr offerings if you can find them and it will stabilize them.
Check your paperwork that came with it and see what the twist rate is and then compare it to the twist rate recommendations of the bullet mfg's you plan to use.
When that day in the future comes to rebarrel it Shilen is a good choice but so are Benchmark, Bartlein, Krieger, Hart, and many others. Today we are not limited to just a handful of good barrel makers like we were 30-40 years ago.
Find a bullet you like that it shoots well, then tweak your load till you hit the sweet spot.
Be patient when shooting and just don't get it hot and keep shooting and it'll last you quite a long time. As a rule if you'll keep to 3 shot groups and not average more than 1 round per two-3 minutes at the bench you'll get a lot of life out of any barrel even in such an overbored caliber like the 7mm STW or 7mm RUM.
I tend to shoot three shots in fairly quick succession and then put it down and pick up another rifle and start with it giving each rifle a minimum of 5-10 minutes to cool down between groups even on cold days.
