Varmint bullet cross sections... Hmmm

So I was trying to understand why the TNT has better explosion than the old Nosler bt I used back in the day when I was an every day groundhog hunter. One year we were forced to buy the Vmax as a subsitute for the Nosler BT due to local supply, and when we went to south Dakota we found the V max had way more explosion than the Nosler BT. Well, I absolutely had no idea they were different.

But the Varmeggeddon is closer to the same as the same as the TNT but it has a thicker jacket.

Here is the V max. It is paper thin with a hollow inside.

My Noslers on pdogs were very meh... They have that massive copper back. Which explains why they hit groundhogs so hard but really were very unspectacular on pdogs. They are great deer bullets too. 1763.jpg

I was leery to use the 55 Varmegedons in my 223a on pdogs because when I shot the 55 bt noslers in 223 they really didn't hit that hard are have explosive kills. Even at 40 grain they were not that great. But now I'm thinking they will work fine.

That being said you can see the Nosler VG has a pretty thick jacket compared to the Speer TNT, and Vmax. I think the Blitzking looks very similar to the Vmax, I could not find a cross section picture.

That is an eye opener . Those pics really show a big dif in construction ,explains a lot . Thanks for posting.
 
Lead cores can be made using different alloys. Sierra has 4 going from soft to harder. It was on their old website.
Sierra makes the core of the bullet from four lead alloys: 6% antimony-4% tin, 6% antimony, 3% antimony, 1 1/2% antimony and pure lead.

Nice photos of the bullets.

Happy to see somebody else is doing bullet cross sections. In comparison with the Vmax, the Nosler BT bullets with their thicker jackets and tapered inner jackets getting thicker at the base appear to be sort of a "controlled expansion" varmint bullet - possibly best suited for dangerous varmints having bullet resistant outer surfaces and stuff like pigs. Should you continue with your bullet analysis the 53 grain .224 Vmax would be a good subject. My favorite VMax bullets are: .204 40 VMax, .224 53 VMax, .243 87 VMax.

Please pass on any wisdom acquired from the master.
 
I did my first load tests with the 50 tnt in my 223a. The further in I seated it the better it shot. Speeds were right around 3720. I'm going to test further in and in either side if the powder charge tomorrow. Not bad for bulk varmint bullet.
