Maybe a crazy question

I have a custom 22br that because of job changes has been stored in the back of my gun safe. The rifle was only shot enough to fire form 50 rounds of brass and work up a pretty good load. The problem is that I wrote down all the components except the type of powder. Here is what I recorded:

Lapua firefomed brass
50 gr V-max moly coated
WSR primers
30.3 gr powder (56.0 clicks on Harrell measure)
3816 fps average velocity (measured on chronograph)
I believe I was only using one powder at the time and must have taken it for granted that I would know. I think I was using one that somehow was highly recommended. The probable options are VV-135, RL15, Varget, H4895, and XMR2015. I cannot cross check this with a scale and the Harrell because the Harrell is in storage and not readily available.
Anyone know how I can at least come up with an educated guess or am I chasing my tail?

I do believe you are chasing your tail! Keep in mind that with any reload or factory load for that matter, we are dealing with an explosion in a confined area, right in front of your face, to push that bullet out of the barrel And by all means please be careful, and review your record keeping process.

futuretrades is right......there's no "educated guessing" in handloading (if you value important body parts).

Your best bet is to hook up with another forum user that has "QuickLoad", that can run various powders through the program and find out which one(s) qualify for your last load criteria.

This should be a good lesson in record keeping fer 'ya.

Powder makers spend thousands of dollars to work loads, for various powders, into various cartridges. It would be fool hardy to use a "Educated guess" for a powder charge. Go back into you manuals and locate a powder and charge, with a given powder, that is in the area that you have data on. If you can not locate said information. I would just start over and work up another charge for you rifle. Better to be safe and sane, rather than sorry and injured. Bill K

Thanks for the replies.
Rick's, Quickload answer was what I was looking for. I know there are software programs out there that might help answer my question but I am not familiar with any of them.
I was going to use the info as a reference but only to work up to, not start with.
