Re: 300WSM Reloading Brass Question

I body size the brass in a redding die, then neck size it down to .334 for my .338 neck gun or down to .337 on my .341 neck gun. then load away. Never had a problem, but guns are customs and have very good match chambers.

The match chambers might help a little...my factory hunting chamber is probably a little loose . How often do you anneal?

Re: 300WSM Reloading Brass Question

Annealing needs are tied to work hardening of brass which is a matter of sizing performed.
Alot of sizing invokes annealing. Little to no sizing eliminates a need for it.

Many assume annealing doesn't hurt, but does it really help? I say often it does not.
Unless you anneal perfectly, A.K.A. lead dip anneal, there is a risk you're adding issues.

Loads fired at or near max pressure will work harden by themselves. MikeCR has a self imposed limit of 53,000 PSI while the max for the WSM is 65,000.

In the LR and big cartridge arena sizing body and neck is a must.

Almost every LR competitor anneals every time normally for uniformity of neck tension.

Lead dip annealing is one of the worst and most cumbersome ways to do it. Hot lead is not the safest stuff to be around or breath!! Do not dip a case in it that has drop of water anywere.

Read the articles mentioned here and on 6mmBR.com on annealing and buy some templac crayon sticks. Correct temp range is normally right at 650 degrees.

There are several annealing machines that make it easy (Benchsource, Ken Light, Giraurd) but it can be done my hand after reading and using the correct temp range templac.

Norma brass is very good, but softer than Winchester, which requires a little more sorting. I use Norma for comp guns and Winchester for hunting rifles.

Not shooting nickel cases are you?

I'm just sitting back taking this all in, a lot of good information.

Re: 300WSM Reloading Brass Question

I typically FL/ neck size every other firing. Assuming you Body die to get the benefits of FL sizing with working the brass less but still bump the shoulder back?

My typical hunting load in my 270wsm is a 130gr Barnes TTSX runing 3255 avg. This load doesn't run through brass quickly but when I was developing for 150gr bergers and got of max load brass wasn't lasting long at all. But like you said that was due to pressure. But I'm done with those as my throat is too short to get a good load.

AidanTE sorry if I hijacked...its still on topic right?
