As someone who has never reloaded, what constitutes good brass and how many times can it be reloaded.
Also are there brass available for 300 wm not available in 300 wsm?
I have just about every brand of brass available but if price isn't an issue, I prefer Norma and Lapua brass. They are in better shape when new and easier(less time) to prepare for loading but they cost quite a bit more. That said, I have shot great groups and killed game with all brands of brass.
For my 7-08 and '06 I buy whatever brass is available and on sale. I use, load and take what I have clean and prepped at that time. They are my woods rifles and shots tend to be at short ranges. Accuracy really isn't impacted in any significant way.
I do tend to avoid Remington and Winchester brass lately but would buy it if I couldn't get anything else. They just take more time to prepare and I tend to have to throw away more, after inspection. Some batches can be awful and sometimes its cheaper to spend more money, if that makes sense.
If I don't want to spend the money on Lapua or Norma brass, I look for Nosler or Starline depending on the caliber. I use nothing but Starline in my 45-70.
I have found Hornady to be ok, as a fall back or on sale. Availability on some calibers and brand can vary quite a bit. In my experience Win Mag brass is easier to find with a better selection of brands than WSM. It is normally cheaper as well.
If your not loading hot with a lot of pressure, I use them 3- 5 times but tend to save older brass for the range and use newer brass on hunts. I inspect new and used brass carefully and pitch anything with dents, dings, creases or enlarged primer pockets. I am particular though and its not the place to save money, IMO.
