Kraky,
I have been fortunate to shoot about as many Sciroccos as most anyone since the very first prototypes and although the pressure increase is a reality, I cannot say that there is a pressure concern. If Stan (OK Shooter) says that there are increased pressures with Sciroccos with a given charge - I would take that to the bank.
I simply load them for accuracy, which is usually near a maximum charge for the particlar rifle. We have recovered a lot of Sciroccos from kills (35 from one bullet test we did on wild hogs) and the Scirocco has proved to be one of the most consistent bullets as far as not shedding its core and for retaining a high percentage of its weight (average is slightly over 80% - regardless of impact velocity).
I do not work for Swift, shoot a lot of other great bullets but am very fortunate to have the opportunity to work with the Sciroccos a lot. They are a great hunting bullet - as are A-Frames and Bear Claws, X's, Grand Slams, Partitions and Failsafes and no doubt others.
Fact is that plain-jane Hornadys, Sierras and Speer bullets will usually make an animal about as dead as it is going to be - they just don't retain as much of their initial weight over such a large impact velocity range.
We should always work up loads from a known safe starting point. Variables such as the jacket material, bearing surface length and actual dimensions vary so much from brand to brand that we can never take anything for granted. I recall making some Mexican-Match a while back, substituted an identical weight premium bullet for a factory load, same O.L. and proceeded to blow the primer.
My experience with Sciroccos has been that they are relatively easy to get accuracy with. I have a couple of sub 1/4 minute groups with them - that is a real extreme and involved a lot of luck, no doubt. I shot the groups that Swift uses in their ads - the ones with the green diamond target.
Swift is likely to come out with a 200+ grain .338 bullet next and I am really looking forward to that one. Right now they make three thirty cals - 180, 165 & 150 gr.- a 7mm 150 gr and a .270 cal 130 grain bullet.
Hope that this info is of interest.
