6mm Hagar/22 Beast (220 Thunderbolt) load data

[bigdaddy1427]

I did a search for Hagar and Thunderbolt load data.
Almost all of the previous post's have the link to Robert Whitley's 6mm AR site, which no longer exists.
Keystone used to have his 220 Thunderbolt info on their site, but it has been deleted as well.
Did anybody happen to save that load data that they could share with me?
I have both, and with the shortage of components, I was looking for the alternate powders and charge weights.
I usually shoot R-15 with both rifles, but that really is not an option right now.
If anybody could help me out, it would be greatly appreciated.

What powder are you going to use? What weight of bullets? And is it Hagar or Thunderbolt?
I’ve reached out to some friends for answers to your questions.
I recently picked up a Hagar upper but haven’t shot it yet (too many projects, not enough time).

Thunderbolt and Hagar should share roughly the same load data.
I am going to be shooting 80's and 88's in the Thunderbolt
87's and 105's out of the Hagar
