Anyone know where I can find some Winchester 375 H&H brass?

I assumed you checked the usual suspects - Midway, Cheaper than Dirt, etc.

I haven't seen any new Winchester 375 H&H brass in a long time.

I have been using Remington and Hornaday brass for my 375 H&H. The Hornaday brass is very high quality.

The last time I checked, Winchester no longer cataloges .375 H&H brass.

Winchester 375 H + H is on a 'yearly' run basis. The do one run and when its gone, its gone until the next run. Remington is available now and is also on a limited basis. So, you will have to settle for it or stock up when winchester makes the next run this spring.

Midway has Hornady Brass 375 H&H Magnum Box of 50 for $46.99 Status: Available. You might have a long weight for Winchester.

I bought two bags of 50 Rem 375 H&H brass at Sportsman's Warehouse. It wasn't pricey. One of the many nice things about shooting a 375 H&H

I just lucked into 100 pieces. I have another option for you- CDNN has Winchester 300 gr FMJ for $29.99/box. It's a lot to pay for brass, but it is Winchester and you can either pull the bullets or use them for practice.

Been using Remmy for three years and get good life out of it, although 50 cases in the last batch of 100 were already at the trim-to length. Gonna try Hornady next order.
