Det har ingen praktisk betydning, om kappen skulle være af blødt stål, andet end at der er risiko for, at den ruster.

Her er der en lille tekst fra Facebook: https://www.facebook.com/militaryarms/po...1628401641
8000 skud gennem en 30-06'er, uden markant forskel på slid, mellem Kobber og Stål... (og stål var mest præcist, de første 1000 skud [8D] )
Det med slid er som han skriver "All the claims of chamber wear, throat erosion and barrel wear are unsubstantiated wives tales."

I get asked all the time "will bi-metal bullets harm my bore". The answer is no, they won't. Here's why.

Hardened tool steel has a rockwell hardness of 650/700 Brinell. Mild steel has a hardness of 120/130. Bi-metal jackets are made from very soft mild steel. Bores/barrels are at least as hard as tool steel and when chrome plated are even harder.

Steel jacketed bullets are nothing new. The US had steel jacketed bullets in WWII chambered in 30-06 and 45 ACP. The M1 ball and M2 AP rounds of the era used steel jackets over a lead core with a copper wash over the steel -- just like Wolf bi-metal bullets.

Frankford Arsenal conducted a test with steel jacketed 30-06 rounds around 1946 to determine if the rumors that steel jacketed bullets damaged the barrels more than copper jacketed bullets were true.
In their testing they found that steel jacketed bullets not only didn't accelerate wear but they also discovered for the first 1000 rounds steel jacketed rounds were actually more accurate! After 1000 rounds the accuracy leveled off to be comparable to the copper jacketed bullets but no evidence of accelerated wear was discovered through 8,000 rounds of testing on their samples.

In short, bi-metal bullets do not do any more damage to your firearms than conventional copper jacketed rounds do.

All the claims of chamber wear, throat erosion and barrel wear are unsubstantiated wives tales.

Hvis nogen er uenige, så vil jeg gerne se kildehenvisninger, til tests der er lige så omfattende som Frankford Arselnals test, på 8000 skud []

Glædelig Jagt fra Grønland

If you can't do it with a 30-06, it likely can't be done...(Men det ER nu kedeligt kun med en gøb....(skriver manden med 10+))
