I am old
I am 60. Still doing well, but when I had most of my adventures I was in my 20s and very early 30s.
It seems like only yesterday sometimes, but other times it seems like "a story I read in a book" long ago.
If you are 58 --------------- you are old too.
HAAHAHAHAAHAHAAHA

I read the article and I think it was very good. In fact about all the info was exactly as I would have guessed. I did notice that the Nosler Partition penetrated 3" DEEPER then the Swift A-Frame at 50 yards, and was 3.5" less in penitration at 200. I knew the 2 would be close.

One thing that I would point out is the they were done with a 300 magnum. I have a 300 H&H but I shoot 200 and 220 grain bullets in it so it's a bit slower then what they are testing.
I would agree that if I were to step up the speeds of my calibers 200 to 400 FPS the Swift would doubtlessly be a bit better mouse trap. I am unconvinced they are better in the guns/ calibers I shoot.

As I said, my fasted gun is a 270 with 130s, and I would shoot 150s and 160 in all my 270s but for the fact that this particular barrel likes the 130s best.

I use that rifle for deer and antelope, and I use my 150 and 160 grain shooters as well as my 30-06 308, 8MM Mauser 9.3X74R and 375 for bigger game. None of the other guns I shoot go much faster than 2900 FPS at the Muzzle, so I have found the partitions are working as designed and advertised. Probably because they were designed for the same parameters I am using.

If I were to get something for big game hunting that shot 3300 to 3600 I might use the A frames myself,(or more Barnes X or Hornady GMXs) but I don't have such a gun and don't desire such a gun, so probably won't be using any Swifts. As I said, I admire them and appreciate them, but they are a "better mouse trap" only for faster guns. 100% success is very hard to beat, which is what I have had with the Partitions now since 1968.

But I can say this to you.....lets do what you said........."we can post pics and discuss this all over again" so we'll both have to hunt and kill a LOT more game, over a LOT more years, and compare wound channels and detail for the 2 types of bullets.

That means we are both going to have to become VERY old men and have a LOT of fun getting that way.
Tough job, but someone has to do it..................

Oh, one more thing-- I may be able to help you with info if you get a sheep tag or moose tag.
If you do get a tag let me know. Depending on where you are going to hunt, I may have some info, or contacts, that would be helpful.
