Just tested out my first batch of reloads for my .270. Not bad, but I'm guessing there's something I'm going to have to improve (see pic). The skinny:
Firearm: Ruger M77 Mark II
Load: Full-Length Sized Federal Case
CCI 200 Primer
150gr Nosler Ballistic Tip BT
51.0gr H4831sc
Range: 50 yds
All seated to 3.380", +/- .002".
As you can see, there's about a 1.5" spread (with one flier), way too much at 50 yards. I used a Lead Sled (those things are like setting your gun in stone), so it's the reload, not the shakes on my end.
The two things I'm guessing I'll have to charge are bullet seat depth and powder charge. I seated the bullet using the method where you barely seat the bullet, black it with a lighter (or marker, when I'm using Ballistic Tips), and load into the rifle. The rifle will shove the bullet into the case, and then you take it out and measure it. Back off the length about half a turn on the die, so you'll have a round very close to the lands, but not right on them. Powder charge is from Pet Loads.
Run-out on the loaded rounds varied from .002" to .010". Not sure why, although I'm going to try seating them halfway, rotating the round, and then fully seating the bullet.
If there's something I'm missing, feel free to let me know! I finally drew a Murderer's Creek bull tag for up in Oregon for the first time in 8 years, and I'm going to get these rounds down pat before I go. Thanks!
