We always take one enclosed trailer with all the camp stuff. Once camp is set up we use it to lock up any antlers we've taken. No worries going to town if no one is in camp.
Yeah, I haven't seen it in quite awhile. I've stocked up on the regular IMR 7828. It works fine. I just finish off each cartridge with the powder trickler.
You may want to try IMR7828 for a little more velocity. You are on the right track with those 200 gr. ACCUBONDS in your 300 Weatherby especially if they group well. I also like the Partitions in my 300.
