Hi all,
Without starting a debate on using 223 on small deer, I'd like some assistance developing the best load. From my research om this and other forums, it seems that the Speer 70 gr semi-spitzer is one of the better choices. Obviously I would like to get the maximum safe velocity and energy out of my 20" AR15 for a less than 75 yard shot. If I find it isn't a viable option then I may have to look into borrowing a rifle in another caliber.
So, while doing my due diligence fo developing the load, I noticed some wide variation in published max load data, much more than usual. I plan on using W748 or BLC-2 powder, CCI 450 primers, and once fired R-P brass trimmed to 1.753".
Here's what I have found so far:
Speer #11 & #12: 2.140", W748 25-27.0 gr; BLC-2 21.5-23.5gr
Hodgdon website: no data for W748; BLC-2 24.5-26.5 gr @2.140"
Since there was no data for W748 on the Hodgdon website, I looked at the 69gr Sierra HPBT and it listed W748 with 24.5 gr; BLC-2 with 26.5 gr
So, I thought I would ask if someone could provide some Quickload data for reference for these 2 powders. I still plan to start at -2 grains and step up by .5 gr, but would like some additional reference info as to what to regard as that max for each powder.
