So I found this video on youtube https://www.youtube.com/watch?v=imcKcKxI6DU&list=PLR31ON9P7uqCedvduzglvyOkA8n6B2G5Y&index=11
It shows initial testing of the "HEAVY 357 MAG OUTDOORSMAN Pistol and Handgun Ammo" Buffalo bore load, a tear down of the cartridge, His analysis, and his duplication of the load with a similarly styled bullet using Hodgdon Lil'gun. Based on his finding they were loaded with 15.8g of Hodgdon Lil' Gun, which is 0.8g over listed max. However that max is listed with with 180g nosler partitions.
I have 100 of the Montana bullet works 180g that he used that should be here Monday. I'm hoping to find some time in the next couple weeks to work this load up from start of 13.0 to max of 15.0, and if things are acting normal, SLOWLY push up to the 15.8 (0.8 over max) over he used.
Will be using a 6in Ruger GP100 for testing. will be running the loads over a chronograph.
Have any of you guys tried similar loads, or pushed Lil gun hard in 357? thoughts about the this workup would be appreciated.
