In my other post in the 10mm Ammo section I had a friend tell me we would see 225gr bullets. Can't wait to show him this ${$default_shocked_smiley}$ ${$default_shocked_smiley}$ ${$default_shocked_smiley}$

Should I leave the sheet as-is? It's really a 220gr bullet and the numbers are really skewed with what's there.

Maybe you can add a column with actual bullet weight.

I guess this lower the KE being a 220 grain bullet at that speed as opposed to a 230 grainer. I still like the meplat though.

Thoughts?

My same friend said the bullets were also not up on the hardness. Wonder if anyone has a tester for that?

4949shooter · January 23 2014 07:57:32 PM MST

Is the 612 foot pounds of energy listed on the sheet based on the 230 grain weight or the actual 221 grain weight?

Also, I would be interested in the hardness issue. I don't know how your friend could tell the difference, but that could be important to us outdoors types.

230gr because no way of knowing if what I fired was 221. If they are all 220ish it's 585lbs or so.

Okay thanks. They still look longer than the Underwood or Buff bore bullets to me.

I think the bullet is not very hard either, and I was surprised by the lighter weight... ${$default_huh_smiley}$

Well then, it sounds like on my next Cabelas run I will be picking up some Buff bore.

Lone Wolf says the Tac length barrels won't be in until May 30th though. ${$default_sad_smiley}$
