Painless load development (mine)

Wish I'd found this method earlier. Burned up a lot of components adjusting charges by .1s of a grain and incremental seating depth changes. On my 2nd rifle now. Much easier.

Tried this out with my 338 RUM and the 250 Norma GTX the other day. Checked for pressure since it wasn't a published combo and loaded where I thought I was safe. 5 shots at 100 yards and adjusted the scope. Moved to the 300 yard steel (furthest my local range has) and was stacking shots on top of each other.

I'll verify with 10 shots at further distance, but I think this combo is going to work. For reference, that's a 1" square on the target.

That's a pretty spectacular group from hammer of a load. Well done!

It's funny how traditional ideology would have you trying to excuse that 1 as a "flyer", or "pulled", etc. I look at that group now and think as long as you keep breaking shots clean like that, that's probably just gonna fill in and be a damn fine load. Especially out of a 338 RUM! Lol.

So true. I still call them “flyers” but don’t excuse them as such anymore. It’s just the group and how that gun shoots with that particular combo.

F***in fliers! 9 shots into like .4" and one just had to shit the bed. I honestly think that may have been a bedding thing, as this was from a Tikka action in an unbedded and undertorqued factory stock and being shot bare muzzle. But yeah, still part of the group!

Heck yeah, and still a killing shot 99.9% of the time.
