Home Forums Reloading Big Game Rifles What’s your favorite 375-06(standard or improved) load?

I started loading for the 375 Whelan twenty some odd years ago. I had no intention of loading jacketed bullets and kept my experimenting to cast bullets. There was no loading data available, so I plagiarized all the data I could find for 35 Whelan for starting loads. I worked up loads starting at 225 grins up to 300 grains. the best powder I found for near max with all bullets IMR 4064. I used a Mark X Mauser Bolt action, Douglas barrel. I don't remember the gunsmith who did the work was. I liked the 375 caliber so much I had a browning 1895 30-06 rebored and chambered for 375 Whelan that I tinkering with now I was pretty consistent with recording my loading experiments with the Mark X so I used that data as my reference for the 95. I think the original data book is out in the loading shed so dig it and pass it on to you. The best cast bullets were the mid weight cast bullets from RCBS and Saeco. NEi's 300 grain bullet was very accurate also, I get back to you when I get time to toss the loading shed.
