After reading this thread: Load development methods...
I decided to try it.
66 gains of magpro,
cci mag primer,
169.5g Wildcat 270 bullets
Just like he described in his original post, I shot loads of increasing increments (1/2 grain) until I got a slightly sticky bolt – this happened at 68 grains. I then backed off 2 grains to 66 grains and loaded three. The above group is those 3 at 100 yards.
This is also the best group I’ve ever shot. I got lucky – but I’ll take it.
I couldn’t be happier. Thanks Kirby. Your method saved me lots of time, powder, and bullets.
