Cadd, I thought you would charge yourself more per hour, LOL.
It's funny but when I break up those preparatory steps into different evening sessions all those preliminary and very mundane steps are completely forgotten, so that when each round finally gets charged then seated it seems like it is going incredibly quickly!

You shouldn't need to crimp. Neck tension alone should suffice. Crimping has been found detrimental to accuracy. You may need to seat deeper and not jam the bullet into the lands so far.
The bullet which was lodged in the throat came out easy enough, and I did not see any real damage when I examined it. There was just a little scuffing where it had contacted the throat, & I could tell that the bullet cocked as I was taping it out, because there's one small un-even ring engraved around it, and it is cocked slightly.
I'm loading these rounds as long as I possibly can and still have them go through the magazine, but even then I'm having to tickle them into position as I chamber the rounds.
I was going to add a little more powder for the next round with these 77 grain bullets but instead I might just try to seat them 0.015" deeper.
I saw evidence of several very accurate loads which were loaded to a COAL of only 2.200" but they were for only 36 grain bullets.
I don't ever plan on going that far. That's just me personally, but nope.
If you are wanting to know for 100% certain of your chamber leade, then make a cast of it with cerrosafe and go from there. Also, cerrosafe is re-usable.

Don't load for what will fit through the magazine. Load for what will fit in the chamber.
If there is a ring, you need to back it off of that. Seriously. If you're having to tickle (another word for force) the bolt closed, they're too long.
Another good source of info. May be worth the 10 minutes it takes to study over it. another good source of study material: http://www.hornady.com/ballistics-resource/internal
