Barrel life 800-1100 rounds!

[jds holler]

So give or take, a dollar a shot for barrels. If the 800 rounds the article reported is correct. Yes, I'm in Houston and no chance of ever wearing out my .22 Hornet barrel I don't think. Maybe, if I could go 1500 miles and shoot varmints. I just thought it was a really interesting article on the Creedmoor clan and then read the expected life and that was a moment. I've apparently lived a sheltered life.

Leo, I'm gonna assume that you're a pretty good accountant.
As far as the lifespan of your Hornet barrel, I think you'll enjoy many years of fun with it. I think I mentioned above that my 218 Bee is around 70 years old, and I doubt that the accuracy is much different now than when it was new.
It was never a 'bench rest" quality firearm, and 1 MOA used to be pretty durned good for most rifles. It still preforms to that level, and that's after something like 2 or 3 bazillion rounds.

Depending on the bullet you're using, your velocity is maybe a little north of 3000 fps. Our Hornets, Bees, and even Vartargs are a kinder, gentler weapon for varmint destruction. And we will be blessed with long barrel life. Heck most varmints even prefer getting killed with shot from one of these sweet rifles. jd

Well, I do ok with ciphering. Me and Jethro paid attention to them lessons. Some of it I pull from thin air though, not empirical data. I agree though, I'll never wear out my Hornet and probably neither will my grandson in the half century or so he'll likely have to try. I plan to load from the left half of the page so 8.2gr 2400 over 50gr 2250fps or 9.0gr 2400 over 45gr 2400fps per Hornady XI. None of the paper I aim at is in too big a hurry for another hole. We'll see once I really get going, but that's the plan for now.

3. I have said this about the 6MM ARC and it fits equally with the 22 ARC, it was designed for the AR15 and when used there is an excellent cartridge.

I'll ask this question once again.

6ARC, 22ARC Said to be designed for use in the AR. That is the standard argument. While the 6PPC and the 22PPC were both developed and primarily used in Bolt rifles for Bench shooting and have been widely successful for that purpose.

What I don't understand is both examples come from the same parent case family which also was not derived for use in an AR. So, I do not follow the correlation that keeps being made.

Yes Hornady tells us that they were based on the same case AND for the same platform, (AR15). In that mode they provide improvement over a standard 5.56 x 45 load, in THAT PLATFORM!
The 22ARC does not practically increase performance over the 5.56 x 45 in the AR15. I haven't explored any bolt thrust issues with the 22ARC however it does exist in the 6MM ARC and therefore it must be assumed in the 22ARC.
In field performance the difference between the 22ARC in an AR and the 5.56 x 45 (in my 20" Colt) is barely perceptual. In the case of a bolt rifle it can perform better than the 5.56 x 45.
Performance improvements of the 6MM ARC over the 5.54 x 45 are also negligible but more easily demonstrated. Comparing heavy match grade 22's in my 20" Colt against the 100+ grain 6MM projectiles I'm my Aero M4E. Both rifles are capable of nasal cavity accuracy, at 400 yards, the 5.56 about 10% of the weather conditions. The 6MM ARC about 90% of the weather conditions in my area.

The correlations are that they're the same base case, designed for the same pressures in the same platform (AR15) and when used there give minimal (in the case of the 22ARC) and reasonable performance improvements ( in the case of the 6MM ARC) depending on range and weather conditions. In the AR15 platform these two cases are near the practical performance level of the caliber and platform.

In bolt rifles you have the same things, same base case however NO MATTER what you do there are other cases in the same calibers that out perform them in bolt rifles.

Doesn't do anything as good as a 22BR?

In my opinion. That is correct.
