Hi all - I'm a new member here, though I've greatly appreciated gleaning information from this site over many years. Thank you all very much for that. I apologize if this is in the wrong section, please feel free to steer me straight.
I'm loading 45ACP for a straight blowback 18" barrel carbine (TNW ASR). There are three different types of loads I'm trying to work up, and I'm hoping you folks can offer some general (or specific!) advice about how things are different with the straight blowback action compared to the 1911 that I'm more familiar with loading for.
1. Typical modest 230gr plinking load, just trying to get a clean burn and minimize wear on the rifle and brass
2. Low noise load with 255gr SWC
3. High energy loads with 200gr and 255gr SWC
I am not satisfied with my understanding of how burn rate, bullet weight, crimp, dwell time and bolt mass are all working together (vs. early opening with the straight blowback action). I have TrailBoss, Universal, and Blue Dot powders to work with right now, and I'm open to other suggestions. (I also have LilGun, but probably not useful here)
Any advice is appreciated, thanks in advance.
