Hello all,
I have been playing with a .28 Nosler for the last few months and not getting the results i desired.
The gun is built on a Stiller tac 300 action with std palmer barrel 1-8 twist at finished at 27.5"
it is mounted into a Manners T4A stock and has a Nightforce 5.5-22x56 in Nightforce Rings.
I has a min spec chamber with a .313" neck and has .290" freebore.
I have tried many load combinations with the Berger 195gr EOL bullet, the best has been with Retumbo and F215M primers.
The problem i am finding is the gun is coming up on pressure before i can get the velocity i was looking for and would like some people to give there impressions on this situation.
i was testing today
195gr berger .020" off the lands approx 3.75" overall length
with Retumbo @ 200m
71gr 2910 fps .2" only 2 shots warm load but no ejector marks
72gr 2940 fps .81" 3 shots as above warm load but no ejector marks
73gr 2990 fps 1.79" 3 shots warmer and ejector mark on one case
74gr 3014 fps 1.1" 3 shots ejector marks on all cases
75gr 3040 fps .94" 3 shots ejectoe swipe on all cases
76gr 3090 fps 1.83" 3 shots sticky bolt left and ejector swipe on all cases
It was very windy so i am only measuring the vertical spread.
I loaded 4 with 71.5gr and shot them and got a .99" group with .576" vertical at 2930 fps
I a little unhappy that the velocity is so low, anyone else see anything like this?
regards Sam.
