300 Win Mag Brass Browning Head Stamp

[Alberta Wexit]

I have some 300 win Mag brass quite a number of years back with Browning Head Stamp any thought s who produced brass. Just wondering have used it with no bad results. Base is thicker. Needs an RCBS 43 instead of the standard number 4 shell holder.

I have some 3006 cartridges and brass from late 60s or early 70s but have been unable to find the manufacturer.

Olin/Winchester produces all Browning ammunition. So safe to say its Winchester brass.
