WEll welcome to the Campfire first of all....

I have checked my data and the lightest bullet I have done work with is the 46 grain HP from Winchester...so I have not done any testing with that bullet to accurately give you a charge.

however I do have some 36 grain Varmint Grenade Bullets and also have a chronograph....

If you can give me a couple of days, I should be able to load up some and test them out...since I know what velocity you are looking for....

I can give you a ball park guestimate, but since you have no chronograph, if you can have a little patience, I can give you an exact in a day or two if that is acceptable.
