Thats not the way I understood it. I heard that some of the bullets at least, the lead core was melting due to sitting in hot barrels/chambers and bullets were blowing en route to the target.
Lead isn't melting in bullets while sitting in any chambers, much less the 3-5sec cycling in competion.
If theres anything Berger knows, its target shooting. Walt Berger was(and still is I believe) an avid Benchrest shooter. Eric Stecker won the F-TR class at the Berger SW Nat`ls. Bryan Litz hunts quite a bit and did great in the Sling/TR class at the Berger SW Nat`ls.
But what do they know of the overbore hunting cartridges added to extremely tight twist barrels -that were most consistently causing bullets to blow up?
I seriously doubt anyone from Berger has competed with a 22-243Middlestead and 90gr VLDs out of 7tw barrels. This condition has probably blown up more Bergers than all other conditions combined.
I was predicting VLD blow-ups for folks, right to the grain of powder, or FPS, while Berger was still denying blow-ups. It's only when shooters who buy & talk a lot of bullets(target shooters) murmured about leaving Berger behind, that the veil of denial was lifted, and actions taken to appease.
But don't confuse this with realities. The original VLDs still blow up exactly where they always have, and there are no competitive target combinations I know of that cause it. ONLY hunting cartridges.
I think Berger's actions present a positive model for many businesses, both with thicker jackets, and with Bryan's velocity averaged BC calcs. I have always loved their VLDs, and buy a lot of them.
But designating thicker jacket VLDs as 'target' seems more of merchandising than practical application. It seems backwards.
If I were shooting a 22-243ai with 90VLDs, I would be using the thicker jacket target VLDs, even while there is no competitive 22-243ai, and never has been.
