[col48]

HI
Went out today to do a bit of fire forming.
nesika k 243 AI Krieger #7 1 in 10 twist.
shooting berger 95g VLDs on top of 47.6g of vit n165


this was my first five shots @ 100y bullet just touching the lands

this is my second 5 shot group 3th in to case

and group 3 3th further in the case

and the last one 3th further in the case.

i have been told that the 95g vld might work in the 1 in 10 twist barrel.can you tell @ 100 if they will be OK????
or do i have to go out to 200y ???
also can i tell even if i am fire forming.?????

they look OK to me.
thanks
colin

With groups like that, you ought to just shoot your fire forming loads all of the time! /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
Check the shoulder of the fire formed brass and see if they're blown out to 40 degrees (I think the 243 AI is 40, isn't it?).
If so, they are fire-formed. Good groups! WOW!

I had a 9.5 twist that shot similar groups at 100 yards, standard 243 with 107smk. At 200 yards groups were considerably larger with bullets showing some key holeing. I'd load some more and test out to 300.
