Slinky Pickle, That is amazing for a the interlock! I would have highly doubted that reliable
expansion could have been achieved. I am very glad to say I have been
proven wrong! I have been testing the Barnes Original 190 flat nose using a
modified (30-30 170gr load) I’m using Hodgdon Varget ——NOTE——- (I found this data to be safe in my rifle,
It may or may not be safe in yours so use CAUTION!!!) What I did was reduce the starting
charge for the 190 by the same percentage as the 170 is reduced from the 150. For each bullet weight the
difference between the starting load and maximum was 3.5 grains. So I applied that to the 190 gr and I came out with
a starting load of 28.0 gr and a max of 31.5, the rifle responded extremely well to this data. My group at 50 yards was about 3/4
of an inch with a Williams peep sight. Now just to check it over the chronograph
