I have two 30 Herrett TC contender barrels, a 10" and a 14". I fire-formed and loaded the once fire-formed cases some time ago. Unfortunately I didn't keep the records regarding which barrel they were fire-formed in. My bad.
I am getting split necks on the silhouette loads in the 14” barrel. I stopped when that happened and did not switch barrels to see if the problem occurred in both barrels. I thought I should figure out what was wrong before trying the 10" barrel. I want to measure the chambers to find out if the problem is the old brass or the fact that I may have two different chamber sizes. Rather than stressing out trying to figure out what happened 20 years ago I opted for a comparison of the chambers to come up with an explanation.
I am going to make a chamber casting of each of the 30 Herrett barrels. Is there any advantage to preheating the barrel before pour the cerrosafe into the chamber?
