Started to mess around with loading for a 6.5x284 about 10 days ago, using Imr 4350 and 142 gr Nosler spitzer, I am now at 45 grns. of 4350, and shooting 5 shot groups at just under .5" at 200 yrds, I tried 45.5 and groups opened up to just over an inch, Question?? will this load take me out to at least 500 yrds? don't have a crno, but am guessing I am going some where around 2700 fps.

Love the rifle shoots great, should I stop here ? or keep going? I have fired 69 rnds so far starting with a new barrel. Rio7

Record where the first shot hits from a cold barrel.

Cold bore first shot on the left edge of 3/4" red dot just barley cut the dot, wind from the right at 10-12 mph, 5 shot group .450, next 5 shot group out of a warm but not hot barrel .490, wish i knew how to post pic's Rio7

Excellent shooting! Most of all you knew where it hit!

I just got back from the range and that's where I record all of my shots from the hunting rifles.

After checking a rifle's zero or firing more shots I write down where they hit and what the load was along with if it was from a cold barrel or a hot one!

Savage 99, I log all my shots and almost always shoot 5 shot groups, so far I have only shot this rifle to 200 yrds here at my house, but I have a 1000 yrd range on the north ranch 7 miles from the house, but it's been raining, so I will wait and go in the morning before the wind picks up. I hope this load has enough poop to reach a ways. Rio7

without running figures, but knowing the 6.5x284, that load should be supersonic to 1000 I'd bet easily.
