[QUOTE="MNbogboy, post: 788145, member: 18849"] [b]Re: test results help[/b] Hello emn83, Was certainly a little nippy this morn...I shot a couple of groups at home with a new lot of bergers and some new brass in a couple of my 260s...I had a gusty 2:00 wind at about 5-10 definitely will spread out your groups....Both were wearing a different scope so after the sighters a .53 & .56 were very respectable for me (the SDs were bad but expected with new brass)...They should only get better after the new brass gets a couple more firings and I fine tune the seating (new dies at Berger make a whole new bullet)... Your charges seem to be in a good node...Normally if you get to your sweet node the groups won't change too much plus or minus a couple of tenths...When you start your seating tests stick with one charge in your case average out your best 4 and it looks like 44.7 or 44.8....Did you happen to shoot these over the chrono? After the first seating test you can narrow that down even more with a couple more seating tests....I generally try .010, .020, .030, .040 .050, .060, .070, .080 &. 090 the first time....The second time I take the two or three best ones and go in .005 increments in each direction from them.... Once I find what seems to be the best seating then I go back to the charge and work both ways from there....If accuracy picks up at another charge then I once again work the seating .003 in both directions...Usually you will find a home for both but sometimes it takes a couple of trys....Better than random chasing your tail. BTW I sent you a PM with the rifle club info. Good shooting, Randy [/QUOTE]
