My hunting seasons are done for the year. Now it's time to get back to recreation. I am going to start load development for my 300 Savage, and 303 Brit. The boolits I plan to use are the Lee 170 and 311466 for the 300 and my lyman 31141 for the 303. The 31141 drops @ .315. Iknow that doesn't sound right, but I got the mold used, and it has always dropped that size, hence the reason I have the lee 170. Any way, I am unsure where to start with powder. I am unsure which might be a better starting point, pistol powders Unique and 2400, or powders such as 3031, 4895, 2520,4350. I also have some others, just in more limited quantities. Starting point advice welcomed, and thanks in advance. I am wanting to develop hunting loads for deer/black bear.
