I'm still relatively new here. I just came across a thread about Thor bullets. I was on Thor's website and it looks like they have bullets sized to .504, .505, and .506 diameter and these might work in my .504 bore Super 91. Just wondering if anyone has tried these bullets in White rifles?

Never hurts to try, email Thor for a free sizing sample.

I followed the directions on the sizing sample I got from Thor. I removed the breech plug from the Accura. Slid in the .500" I used a range rod with a .45 cal flat tipped jag so as not to flare out the skirting on the bullet. The bullet went thru the bore with just a bit of resistance. Then I tried the .501" I couldn't even get it started down the bore. I had to go in from the muzzle and knock it out.
So I guess that means my rifle takes the .500" - huh?

As long as it won't move off the powder. I like them to push in harder than Jon. What he thinks is just right. I think is too loose.

Terry at Thor says as long as it won't move off the powder. It's a good fit.

Doesn't the powder need some compression??

Yep! That sounds just about right.

Thor's are basically a .500 diameter bullet with a skirt sized to order. They work very well in my .501 & .502 diameter bore rifles. I'm only guessing, but I think it would be somewhat difficult to get the bullet to obturate fully to a .504 diameter bore, even if you could get a snug fit with the skirt. I would be surprised if you could get stellar accuracy with a White. Why not stick with the 460 grain NE or BS conicals the rifle was designed for?
