24.8 shows promise though fps was slow at 3300 so was thinking of moving on from 25 carefully to see if i could find a second sweet spot.not bad for the first batch in winds gusting from 15-20 mph and 0 to half value
Agreed, I analyzed your groupings before reading your post, I had 25.2 as well. I ended up seating the 39 sbks to 2.260". Groups were cut by about 1/3" from 2.25 to 2.26. When you land on your seating depth, I'd be interested to know.zx10mike wrote:
onwards with the sbk it is then i do like it when a load has a big accuracy node if i go with 25.2 i have room either side if the powder measure is .2 of a grain out.
I did .010" from 2.200 to 2.28. There was another decent node at 2.2, but the 2.26 was the best. I have it on my list to go back and check 2.255 and 2.265. I have consistently shot around .5" groups at 100 yards with this gun, but was shocked to see that group shrink in half on a round robin test including the cold bore shot. I retested the load and got another .3" group on a 25 shot fouled barrel. Took me almost 3 years, 4 bullets, 3 powders, 2 primers and about 200 rounds to finally get what my gun likes. Guess I should have bought a cooper.zx10mike wrote:did you alter your seating 10 tho at a time or less?
Just means how I shoot my groups while doing load development. For different charges, I will shoot 1 shot of one charge, then move to the next charge and shoot a shot, then the next and so on, then come back for the 2nd shot of the first load charge and so on. I do this with seating depth as well. I feel like it removes some variables like shooting fatigue, barrel heat, etc..., however I think it adds some variables specifically related shooting form. I found, if you can shoot a group round robin, it will look as good or a little better for consecutive shots.zx10mike wrote:round robin test?
