I have had several good 6.5/284's over the years but since everyone pretty much moved to the 6mm and 30 Caliber I did the same but lately I have gone back to my 6.5/284 because they are better in the wind which is always blowing on our range. For the shooting school I used a 6.5/284 I built two years ago it has a 30 inch Krieger barrel with a 1-7 twist normally I use a 1-8 but I built this gun to shoot the new Sierra 150gr match bullet but after 200 rounds I gave up. I simply couldn't get them to shoot good at 1K. so I didn't play around with this gun to much I new it would shoot the 142gr SMK but even those were not grouping as good as I hoped.
So I decided to use this gun in the school and test some different loads and see what we could do to make it shoot better to make a long story short I found out that I was using one full grain of powder to much I didn't have any pressure problems with that load but I didn't have any accuracy either I ended up going down from 50.5grs of RL16 to 49.5grs of RL16 with 142gr SMK and a BR2 primer and the gun really started clustering shots at 1,000 yards something it never did before
sometimes you get a mental block and don't want to reduce loads and since all my other 6.5/284's shot at least that 50.5 to 51.5grs of RL16 It didn't seem likely that this would help but every barrel is different possibly when it starts to wear it might take more powder but for now 49.5grs of RL16 seems to be a winner.
