Neck Tension, Pulling Bullets, Mexican Match

[RoscoeT]

This is my first load I've worked up for my .243

I goofed and had to pull a few bullets. I'm not crimping.

I changed the charge in these cases and re-seat the bullet. I notice that the newly seated bullets seat with a lot less force. Will this lower neck tension have any noticeable affect accuracy?

I do not want to throw off my testing since all the cases holding the 40.5gr charge have less neck tension than the others.

I doubt this is a major concern however. But I wondered if I had to re-size the neck only how could i do this with my lee FL die?

Also, I am having a bit of trouble finding a good deal on a large amount of brass. I found a guy willing to part with some Ingram .243 ammo for about the same price as I can buy new brass.

I thought that I might make some "Mexican match" ammo with it.

Is that brass any good at all? Or should I just buy new high quality brass at $0.50 each?

What is it you are using the brass for?

Target shooting, Hunting, Plinking?

If you want the very best buy new Lapua.

If your using these for hunting loads, the brass from the ammo you are looking at would probably be sufficient.

Forget spending the time making "Mexican Match" and just shoot the already loaded rounds.
