Barrels
Which is Stronger - Damascus or Twist ? It seems to me that the ''cheap''
early doubles had Twist steel barrels and more expensive doubles had Damascus steel. Yet the 8ga. Parker (made in about 1912) that I looked at last week end had Twist steel barrels. Harry |

Damascus was considered higher quality than laminated and twist steel. Which is “stronger” would really be a subjective opinion. Some may say twist is weaker. But I would say that Damascus has more forge welds than twist, so why would that not be weaker? Ultimately they are both composed of two different materials forge welded together around a mandrel in order to form a tube.

Harry, we have seen other types of composite barrels on higher grade 8 gauge guns.
The grade of the gun is what generally determined which barrel steel to use on it. The various Twist barreld were used on grades 1 and below, regardless of the gauge. .

A grade Finest Quality 6 Iron "Turkish"
A grade Premier Quality 6 Iron "Turkish" Both guns were part of the Meachum order re: pattern welded strength the winner of the Birmingham Proof House Trial reported in 1891 was English Best Laminated Steel. This is not the same barrel as Parker's Laminated Steel. This includes actual tensile strength testing https://docs.google.com/document/d/1...hfDxmrNAU/edit The sample size was limited (getting back to finding Zircon's 30 barrels ) Pattern Welded mean psi after discarding the highest and lowest numbers: Twist - 53,333 psi Crolle - 54,700 psi
