Preadator53,
I loaded 12 different loads with IMR 4060 and H380. I still have two more powders to try, Varget and H4895.
IMR 4064 is a stick powder and H380 is a ball powder. Out of those 12 different loads I came up with, I narrowed it down to 3 loads with these two powders.
IMR 4064 42.5grs 58 gr V-Max velocity 3680avg group .680 3-shots 100yds
IMR 4064 43 grs 58 gr V-Max velocity 3720 avg group .630 3-shots 100yds
H380 49grs 58 gr V-Max velocity 3889 avg group .455 3-shots 100 yards (This is my favorite load. This powder meters so nice in my electronic power measure. I had only a 5 fps variance between all three shot which just blew my mind away. This is max load on this powder but show absolutely no signs of pressure.
My Collective overall length of the round was 2.660 and I used 9 1/2 Remington primers. Next time I am going to move the bullet out to 2.700 COL and see how this works. I will let you know.
Next I experimented with the Berger 105gr VLD and had great results with these bullets too. I used IMR-4350 and H1000 powders.
I don't know powder charges off hand since I am at work and don't have the info in front of me. I do know COL of the shell was 2.770 and go this round shooting in the 2800fps area and still had room to get this round moving into the 2900 fps area. These Berger VLD are a very long bullet measuring 1.292. I found the maximum COL of my friends gun to be 2.890. This is where the bullet is touching the lands. So next time I load up these round, I am going to seat these bullets .020 (2.870 COL) off the lands and see if i can tighten the grouping of these rounds. The 5 loads that my friend shot were just a little over an inch group and they all shot the same group between the powers.
I will keep you informed.
