Thank you Huntchick, your numbers make sense. Yes, I do have a chronograph and can shoot on my own property, which helps for a quicker load development.
So far I have been using some Win231 for plinking. 6.5gr of that stuff combined with a Nosler 135gr JHP results in 1,150fts. I was a bit apprehensive pushing things above 10gr on the Acc#9, seems to be a way less economical powder. Is it getting close to compressed, once you hit 12gr ?

Greetings from Central Oregon.
I'm fairly new to reloading and have spent the past couple of hours trying to find reload data for (polymer coated) 200gr hardcast. Seems to be the biggest secret on the planet
So, I have the above mentioned combo of Badman's bullets (local Oregon supplier) and Accurate #9 which I want to put to use.
I was thinking about a COL of 1.250" and working my way up to 1,100 ft/s. Would 10.5 gr of accurate #9 be a safe start ? I have a ballistic chronograph to measure progress.
Also, I want to use these bullets both for plinking and wilderness defense (black bear and other Oregon undesirable species). Any suggestions on how to develop optimal loads for both occasions ? Thanks !
My 10mm Handguns : full size S&W MP2 and XDM Elite Compact.

Central Oregonian here, by way of Belgium. Was referred to this site by the AKFiles. Picked up two 10mm (S&W Full Size and Springfield Compact) for my outdoors adventures. Been in too many close calls with wildlife over the years for which my 9mms would not have cut it.
Am about to start reloading for both these guns and a new S&W 5.7. Looking forward to diving into the wealth of information on this site.
