splitting case necks

This is my first post and I could really use some expert help.

I am slightly new to reloading. I understand the basics, but do not know enough information or have the tools required to find out certain things. I am currently using a .308 Rem. 700 police action on an AI stock. I started reloading 155 gr HPBT with re-15. I have never loaded up to the maximums I have found in all the reloading data I have. this weekend I went out and ran through about 15 rounds and found that 2/3 of the case necks split. Not only this, but at 600 yards my rounds were all over the place. I am not saying I am an expert marksman, but every time my rounds were hitting low. So i would raise my elevation, shoot, then it would continue to be low. at least 7 times I raised my elevation, but still hit low of the target. I pulled one of the rounds when I got home and found that the powder was around 42.6 to 42.8 grains. Can someone just give me an idea if they might know what is happening?

Re: splitting case necks

Your brass is hard and you need to either anneal the necks or toss it. As for hitting low where you just holding over? If so you've come to the right place to get straitened out, folks here will get you lined out pretty well on better methods, and don't forget to drink your cup of humble when you go shooting.

Wow, where to start?
first, find an old grey beard at your shooting range/club. get to know him/her, ask for help. and learn how to anneal and trim brass, it's not hard to do.

You put the case in a flame for a small period of time (anywere from 5-15 seconds depending on the temp of the flame and how hot you want to get your cases) so it softens the case. You only want to soften the neck, softening the head will cause some serious safety problems. Do a search to get a much more detailed answer.

Re: splitting case necks

I strongly urge you to buy several reloading manuals and READ them. Without basic information you are headed for a really hard time in loading.

Very good advice. Also, to learn more about annealing go here:
