We are setting up our machine to produce more 338 cal jackets right now. We have run into some tooling issues as we are making jackets with a few modifications that didn't work out with the first set of tooling we tried. I am confident that we are on the right track now and should be making more jackets by next week.
To be clear, these jackets are different than the jackets we used to make the original bullets. I won't go into the differences as the first of these jackets will be thoroughly tested to see if we've resolved the "high pressure/velocity" issue. If these jackets don't make a difference then they will never see production and we will go in another direction. We'll know more soon.
RDM416,
One of the most challenging aspects of this situation is that it is not occuring at a consistent velocity and/or pressure. We have some people reporting diminished trajectories (consistent with a lower BC) and poor precision at velocity as low as 2850 fps. Then there are others who report the ability to go faster without any problems.
In our own testing we were not able to make the bullets perform poorly even with loads that we believe were pushing the limits of being safe. We have not officially eliminated the possibilty of nose slump but given these inconsistencies in results it makes it far less likely that nose slump is the true root cause.
I'll add that the reports of poor performance are few and far between but some of these reports are coming from people who we know to be very capable so we regard them as genuine. I am not suggesting that others reports are not factual but if a few the folks involved told me that the sky was green I'd have to figure out what was wrong with my eyes because they are that capable and I trust their abilities and powers of observation that much.
If you or anyone has a chance to shoot our bullets at higher velocities (using safe loads) and posts their findings I will be grateful as the more data the better.
Regards,
Eric
