I am new to reloading and have finally accumulated enough equipment to reload my first batch of ammo. I have a Dillon 550B and plan on loading ammo for my Glock 23 with a Bar-Sto semi drop in barrel (full chamber support). I am using new brass since I am relatively new at this. I am reasonably well read, but no practical experience yet other that practicing the different stations independently for powder measure, crimp, etc. Just haven’t made a shootable round yet.
I plan on using a 165 gr bullet with Bullseye powder. Even though I have a progressive press, I plan on checking (weighing) each case until I get the hang of it. I have Montana Gold FMJ and Speer GDHP bullets at my disposal. I was thinking on going with the Montana Gold first since the Speer were 10x as expensive. Both are 165 gr. Do the two different types take any special considerations such as different OAL?
Bullseye and Blue Dot are the powders I have in stock. I have chosen Bullseye but have a question on some of the data I am reading in two of the more popular manuals. I plan on starting with the minimum load but,
The Lyman 49th edition lists the following loads for Bullseye powder, 165 TMJ : Starting 4.8 Max 5.4 COL 1.120
The Speer #14 manual lists the following loads for Bullseye powder, 165 TMJ/GDHP: Starting 5.3 Max 5.8 COL 1.120
The Speer manual data matches the data listed on the Alliant web site for the Bullseye load.
My main question is why the difference?
Any advice on which minimum load to start with or any other advice for a newbie loading the 40? I know it is an unforgiving load but the only pistol I have for now.
