Re: Loading with bullet close to the rifling/lands - R92 .35

Following on from what I thought was a successful day out with what I thought were "real" FMJ projectiles...........
Not sure whether to be irritated or not. Recently bought a bag of 500 (labelled as) "ACE Bullets - .38/.357 158gr FMJ FP" as I wanted to try some higher velocities from my Rossi using Alliant 2400. Shot some at around 1450fps believing them to be FMJ (using 12,5gr 2400) and was pleased with the results.
However, I have just noticed a small card buried in the bag which states "LOS Copper Plated Bullets" -Made in Slovenia - http://www.los.si
A look at the LOS website reveals that they are plated, swaged bullets; I cut one open and compared it to a PPU FMJ and the copper is about half as thick as the jacket of the "proper" FMJ. Still quite thick though, perhaps 0.006", but further research on American sites (e.g. Berry's Bullets) and forums makes it clear that these plated bullets should not be run any quicker than normal lead projectiles. Berrys suggests keeping under 1250 fps.
Furthermore, these LOS bullets have a swaged core which is, I believe, much softer than the hardcast plain lead projectiles.
My question, then, is whether any of the long-time .38/.357 reloaders on here would recommend continued use of the LOS Plated (but sold as ACE FMJ) at 1450fps or am I just asking for trouble? It looks to me as though they should probably not be shot at much over 1050fps as noted on the "Black Rifle" website (although "West Wales Models" suggest that they have been "tested at velocities above 1200fps").
Thanks in advance for any info or experiences that you can share.
