OK, after another day at the range this is what I'm going with.
I shot 5 different 3 round groups. This one is average. I'm pretty happy with the results. This was shooting off a bench with no vise. If I do close to this well in the field I ought to be OK. I will be using shooting sticks afield so using the bench isn't too far from hunting conditions, well besides buck fever, low light maybe, etc. etc. and all the other variables!
Sabotloader the sabots I have are stepped in the cup with machined, (molded), numbers. I tried them again and they are just too tight. I'll stick with the Hogden Great Plains HB HP 385gr. for now as I like the results. I hope to post a picture of a hog dropped with one this weekend. Wish me luck!
Thank you all for your help on my quest.
