Hello all...... I am wondering if anyone can help me out??? I have a 300wby ultra light wieght that is being stubern.... The gun has only had maybe 200 rounds through it and I clean it really well after around 25-30 rounds........ Ive just switched powders and bullet and am having wierd results....... Ive been trying to find the tightest group with that new powder but am getting a lot of flyers, I will shoot 3 shots that are touching each other and give the gun a cool down and then shoot 3 more and they will be all over the map............
I dont think its my hand loading..... but let me know if this sounds right....
I wieght sort my cases, trim them all, i use Fed. Match mag primers...... i use a digital scale (i do re calibrate it after about every 5 rounds and take random samples and re-check the charge to make sure its right..) (is recalibrating it that much too much????) I use Redding Comp. dies and check the OAL of every round (witch I really dont need to with these dies)
Now ive even tryed shooting without cleaning and get the same results, ive tryed cleaning after every 5 shots.... same thing......
Now the reason I posted this in optics is i think its my scope........ I have a B&L 4200 3-9x40 When ive been at the range i havnt mooved the cross hairs just because ive been shooting so many diff. charges and powders, So i paper the Whole back stop so i dont have to change the elev. or windage..... Now im finding my windage is usually on its the elevation thats off........ IS this a scope problem????? Im thinking it is cause i have had that gun on many planes, even strapped to the out side of bush planes.......So im thinking the scope is getting loose....... any ideas???
thanks
