[QUOTE="Fiftydriver, post: 379271, member: 10"] Master Diver, Not the 408 CT cases but I have seen some of the 338 Lapua versions. Good brass, would not say any better then the Lapua but good. From what I have heard, the cost is what would keep me from using them. Likely just the import tarriffs but pretty spendy brass from what I have heard second had. Never talked to them or gotten a price list even though I e-mailed and requested one a couple years ago. I have been talking to a few guys about the new Bertram brass made in the last year or so and they say its much better then the older versions which were extremely soft. Sounds like the same situation as Jamison but those I spoke to that had used both the new Bertram and curret Jamison brass said they were going to just stick with Jamison to support a US company as there was no real difference in brass quality. So I stand corrected so some degree. Seems the new Bertram brass is decent strength but still no better then the US made Jamison as far as taking pressure. The brass I sectioned and tested was made several years go but the TTI brass which was also said to be made by Bertram was at least the same age and there was absolutely NO comparision between the two, the Bertram brass would loose a primer pocket long before the TTI brass even started to get rolling. In fact I looked up my test load log where I tested this brass and there is the max loads for each brass. By max load I mean the point where the there was a noticably loosening in primer pocket tightness on the first high pressure loading. Bertram 300 gr SMK...........139.0 gr H-50BMG.............3223 fps TTI 300 gr SMK............148.0 gr H-50BMG.............3418 fps Current Jamison brass is around 142.0 gr with an average velocity of 3289 fps in a 32" barrel length. (As a comparison, Black Sunshine, my 40" barreled 338 AM produced 3502 fps with the same load with the TTI brass which was a usible load) Now, this is not saying that the rounds could not be loaded a bit higher. I have customers currently using the Jamison brass that are pushing 3400 fps with 33" barrel lengths and getting many firings per case.
