THOR Lightening one size diameter bullets to tight

[ABOmaster]

I have a new in-line CVA .50 cal ML. I ordered some Thor Lightening one size diameter bullets to try as we cannot use sabots in Colorado. These are suppose to not require the sizing pack like their Hammer bullets. They are suppose to be tight fitting in the barrel but these seem extremely tight. I'm not sure that the recommended 30 lbs of pressure would force the bullet down the barrel. Does anyone have an any experience with these bullets?

I’ve Never used the Lightning. My rifles use the .501” Thors. Sounds like you may need the .500”. Sizing Dies are available from Arrowhead Sporting Goods & Hanks Precision Gun Parts. Good Luck, your Season starts Saturday Sept.11th

These are fairly new and not suppose to need the sizing dies. I emailed the manufacturer but have heard nothing back as of yet. Not hopeful. Thanks anyway.

Hopefully they will exchange them for the .500” diameter
