Ok,,,,so after a couple of more shooting sessions the last couple of days I think I have by chosen loads, both hunting and shooting practice, figured out. I stuck with Varget for 130 gr. TTSX which I was using for my TSX hunting loads for my sako .308 and got better groupings the the TSX were giving me.
I used Dan Newberry's OCW process. I was a little hazy about how to choose the best load according to figuring out where the "node" or "Optimum Charge Weight" (if you prefer) was but with a bit of head scratching I think I've been able to interpret the results properly. It's pretty hard not to just go with the best (tightest) group and choose that for your load, though, which Newberry explains might not be your best choice.
According to Newberry, he says you can fine tune your loads to make tighter groups by experimenting with seating depth. But how much of a change in depth? Would you go up and down 10 thousandths from the loads I tested yesterday ,,,,,or should I use a smaller increment like 5 thousandths? I'm thinking 10 thousandths because I don't want to use up all my expensive projectiles. LOL
Or would you even bother with this part of the load development process?? Maybe i'm being OCD. LOL I'm curious to know if most people do this or not when using Newberry's OCW method?
I will probably be doing this just with my hunting loads just so I can have the best accuracy possible, I'm not too worried about my practice loads which should be MOA as long as I do my part but I may try tweaking those loads here, as well, with seating depths.
On another note, how much of "doing my part" is affected by a stiff head wind because I sure wasn't overly exciting by some of the results today. I didn't think the wind would have too much of an affect over 100 yards,,,,,so, for 100 yard shots, how much will a fairly strong head wind affect your POI?
Looking forward to people's comments regarding POI and tweaking it by changing your seating depth~
For those of you who are not familiar with Dan Newberry's OCW method of load development give this a read. After you've read the overview, be sure to take a look at his step by step process. It's well worth reading!
