Do the general guidelines for determining the charge quantity for Blue Dot reduced loads (where you measure the total case quantity of Blue Dot. . .start at 20% of the total and then work up to the maximum which should be somewhere between 50-60% of the total case quantity of Blue Dot) hold true for the very small cases like the 22 Hornet?

Thanks for any guidance you can provide on this question.

Sunset,
I have not worked with cases as small as the Hornet... the 222 and 223 are the smallest...

the 20% rule definitely holds true.. and one is wise to slow down at about 50% case capacity...

it is real important to work up slowly from there..

short fat cases seem to be preferred by Blue Dot, or longer ones...

case in point.. a 284 case can run true with the 60% rule, as a WSM case can.. however a 280 or 30/06 case top out at 50%...

In a Hornet case, I'd recommend working between 20 to 40% of max case capacity and go work up beyond the 40%...

Case capacity is defined as filling powder to the brim of the case, and then leveling it off with a 3 x 5 card or something like that.. then weighing how much is in the case...

start at 20% of that figure there....

best of luck..
cheers

The Hornet is usually loaded with N110 which is only a little slower than Blue Dot. I do not have my copy of QuickLoad at hand but I am quite sure that the maximum possible load with Blue Dot is pretty close to the 8.8. grain of N110 which Vihta recomends for 45 grain bullets.

Personally, if I wanted to go down as far as 20% LD I'd choose a faster powder.

Like stated, work up SLOWLY and do not trust anything you read on the internet!
