Start low and work up as always. Then you can tweak the seating depth for best accuracy.
I've had great success with this powder.
I use fed 215 primers but alot of folks also have good results with the cci-250's
I would also use the muzzle break- unless of course you think it was installed in an improper manner.
Thanks for your inputs. I have felt like the lone ranger since I have had this rifle. I just bought a can of acurate 8700 to try. I will look for this US 869 as well as the175. I have some 175 sieras. Where did you get the load data fo rthe 869?
I will play with the primers some more if I can find them.
The muzzle break, now, I had the mercery stick put in the stock of a 300 whetherby mag and loved the results. So when I went back to have one put in the ultra mag they had this new thing called the Q. They sold me on it so I had both put on, the Q was around 300 bucks instaled. with that and the mercery stick you can let a 10 year old shoot it! thing is after loading some rounds they key holed. I blaimed it on the loads and went back to the origanal loads I had made and continued hunting. They seemed OK. After season I could hear a rattle when I jared the rifle. It was the Q. I couldnt find the gun smith that put it on and he apears to have gone under. I took it to another gun smith who had no info on the Q. The mounting of the Q seems to be fine. If I screw it all the way down it is quiet but not properly adjusted. So I just screwed it off. It is adjustable supposidly to help tighten a group with different bullets. Between that and reloading, what a headace. For the money, the company should back it up. I think it was installed right but wore out fast.
any info on the Q would be apreciated. I have left the mount on just in case and just shoot with it screwed off for now.
Also more inputs on the ULTRA Brass inspection would be nice.
Thanks for all inputs
