I have a Cooper model 52 in 6.5x284 and have been working up a load using Reloader 26 and Berger 140 VLD hunting bullets. First off I'm not an expert shooter by any means and this rifle will be used for hunting and long range target shooting. I've been loading 55gr Reloader 26 in Lapua brass with cci br2 primers. I ran this load over the chronograph when getting the scope zeroed with an average of 2986 fps. The speed was very consistent with the the first shot at 2976 the last shot at 3001, and three in the middle at 2984,2985,2987. I did a seating depth test as Berger suggests and at .020 off the lands it put them all in one hole at 100 yards. Seated farther off the lands in .030 increments the groups progressively got bigger but the largest group was only about 5/8"
I loaded up more and wanted to see what they would do at 500 yards, and also kind of verify what my chronograph readings were. I entered all the info into Strelok and it gave me a correction of 6.9 moa. I dialed it and proceeded to send some rounds down range. After the five shot group I was pretty happy to see the results. I'm not sure what happened with the flyer but most likely it was me and not the equipment. They all were a little high and after I made a velocity correction in Strelok the corrected velocity is 3090 fps. Next outing I'll take them out to 800 and 1000 to see if that holds true.
This load doesn't seem to show any pressure signs at all but I must be getting up towards the upper end going by the velocity I was getting. Maybe next time I can work on my technique more and get rid of the flyer.
