You know This Quickload program lets you mess with all sorts of different variables. Its alot cheaper than buy some, load some, shoot some method ive been using for years. It's a great tool.
Im up right around 1300 fps now with lil gun, I slugged the bore and it was a little larger than I thought,
Im gonna dissect the 147bt xtp and the 180 xtp to look at the difference in jacket thickness to see if I
can't design a 180 bt that may be more appropriate for the velocity/ expansion range Im running. I like
to make bullets!!
I feel the 180 loading just gives a little more life (and usefulness) to a very obscure but addictive
cartridge. This may make an awesome SD load in the G-29, just have to deal with the over
penetration issue.
