OK, my bad on ".303 Savage". I went back to Sav 99 restification and found that the Sav 99 is
.30-30, not .303 Sav. Either way, that cartridge will do it with a deep HPt cast or a dual alloy
cast soft point, but no point is subsonic with it that I can see. You are already launching a super
heavy .30 cal cast with the .300 BO. If you go for max speed, the .30-30 brings a lot more
to the party in the way of powder capacity, so you can either be conventional and use a
Hornady 170 gr or go cast with ......deep HPt or dual alloy cast SP. Is there a broken record
around here? Is the 170gr full power .30-30 too much thump for your retinas?
But you already knew all this was out there. I guess the issue is that you didn't expect the
solids to do as little as they did. Simplest step is upping the game on the cast with the
same gun- deep HPt or dual alloy cast SP. Lead is still the issue, but you hit many times so
it seems like you have that working.
As to Brad's suggestion, a bit of corn on the ground at the right place should get the range
down and get them to hold still a bit better.
