anyone have load date for 375 win savage 99 brush gun Speer 235gr hot core semi Spitzer projectiles I have IMR 4198 IMR 4895 and IMR 3031
This is what I saw on another forum but I’m not a fan of going off online info hoping someone on here has tried and proven info IMR4198 start 28.0 max 32.0
IMR 4895 start 32.0 max 36.0
IMR3031 start 31.0 max 35.0
I would prefer using 4895 or 3031 as I have more of that also for COL any references from someone else who uses the Speer bullet in same gun
With a 235 grain bullet I would employ the 255 grain data, and start low and slowly work up. Remember, the old "home pressure reading techniques" as espoused by Ken Waters and many others a generation or two ago have been proven false. If you get primer flattening, case head expansion, sticky bolt lift, etc. that were the accepted parameters, you've probably already been dancing in the realm of excessive pressure.
I love to read the old Ken Waters stuff. Heck, I bought those magazines back in the 70's-80's mainly to read his words of wisdom. But, today I consider it anecdotally good bedtime reading. Stuff has changed in the last 30-50 years plus he was flying basically by the seat of his pants with no pressure equipment to quantify his data. He even often issued stern warnings that his data was what worked for him on that given day in his guns. Given the choice between data published by a gun writer in a magazine in 1978 versus data from a modern up to date manual achieved under strictly controlled laboratory conditions, I'll opt for the data in the modern manual.
