Mixing brass?

[MD]

I don't own any reloading gear, but bring components to a friend's to reload.

For several years we've been reloading for my 300 Winchester magnum and using a mix of plated Federal and non-plated Federal brass, some Winchester and even some Imperial brass.

I wonder if there is an appreciable difference in loads we make that is created by using different brass?

I have had some inconsistent sighting in experiences and I just thought it was me, not the gun or the cartridge but I'm starting to question that.

brass can change how a load reacts but it tends to be very minor (in my experiance) how far are you shooting? if your sighting in at 100 for hunting then the variations would be so minimal you probably wouldnt notice.. burs/no burs on in the flash hole would give you more variation then brass manufacturer as it will cause the poweder to bur differently, then a nice bur free flash hole

if your shooting BR / precission rifle then i would keep the brass seperate and load them acordingly, talk to the hardcore BR guys and there is no end to how perticular u need to be about brass

In reply to your reply ultimate monkey, yes, the shots at 100 seem okay. Not spectacularly tight, but good enough to bag a couple Vancouver Island elk, a deer, a moose and numerous bears at various distances over the years.

At 200 metres, I often get two good ones sometimes two to three inches apart and a flyer though. Made me wonder if it was me, the load or the gun.

I would segregate for headstamp, and separate plated from all brass. You would find it interesting to weigh the various pieces of brass you use. The more brass equates to less volumn and subsequently more pressure. What did your R. elk score?

horseman2,

Thank you for he reply. I got a 6x7 bull elk in 2002 and got a cow elk in 2007.

I don't know how to score antlers.
