Have had some interesting conversatio via E-mail with some people at Western I thought I might share part of it with those interested.

Lee,

Thank you for you interest and kind words about Blackhorn 209.

You can use 0.7 as a multiplier i.e. 100 volume units x .7 = 70 grains by weight.

We will work on something for side locks, but can't make any promises.

Best regards,
