Just curious what these rounds are coming out of , length of bbl etc .
I just got back from the range shooting my 300 winnie with RL22 and 190 smk's . Strange doings for sure .
I had previously developed a load using these components that has shot .3's at 100, .7's at 300 and 2" and a bit groups at 700. Load was 73.2 grs. of RL 22 under a 190 smk out of a 28" bbl. This load was avging 3050 over an Oehler 35p.All this out of a 28" Broughton 5c bbl
A short time ago I realized that I had not pushed this combo to the doorstep of the OP dog ( overpressure )So , I loaded up some all the way to 74 grs . 73.5 grs had a esof 15 and sd of 7 for 5 rounds and went into .4 something at 100 , 73.8 grs also had a es of 15 and a sd of 7 for 5 rounds and went into .3 something at 100 , 74. grs had a es 0f 22 and sd of 9 and went into .162 at 100. The first two strings were 5 shot groups and t6he last was 4 shots because I did not want to fire the fourth shot...............not because it might mess up the group but because I wanted to weigh iot to see if I had put the last two strings out of order in my ammo box . The velocities were that crazy with the last 5 ( 4 ) shot group.
I will pursue this madness , 3100 fps 190smk's is kicking for an accurate load out of a 300 winnie and there are no op signs at all !
Reckon my point is to " keep on looking " you never know what you might find .
