So I've been developing a load for my Savage 6.5x284 for what seems like an eternity now. Finally about a month ago I found a load that shot .354. I had to scrap my old brass before I could retest that load, but with brand new brass I shot .455. I finally thought I had found my load so I loaded up 10 rounds to shoot at 300 yards this past weekend. Here's the load: Norma Brass 140g AMAX .010 into the lands. Fed 210 primer 51.0g H4831SC I shot all 10 rounds this weekend and what a disappointment! Here's the results: Could only stretch it to 283 yards where I shot that day. This is max load for my rifle. I get minor extractor marks on the case head but it's by far the best velocities and ES out of all the loads I've tested. Of the 10 shots, I took off the highest and lowest speeds and the average was 3074 with an ES of 14. Again this was with brand new brass so I know I will have to retest again with fire formed brass. My new brass prep included neck sizing, turned necks, trimmed, chamfered and de burred. Any thoughts on why I am all over the place with these 10? I know I am no where near being a good 1000 yard shooter, but 283 yards is not a difficult shooting distance for me at all.
