I shoot the original 150's out of my 7mm Rem Mag and have had awesome results. I like them so much I bought up about 500 when they switched to the Scirocco II's so I'll have plenty for the life of the barrel on that rifle. I think you'll be very well pleased with the accuracy and their performance on game is devastating. I shot a Midwest whitetail through both shoulders and recovered the bullet just under the skin on the off side. It mushroomed perfectly and still weighed 132 grains. The deer went about 20 yards before he flopped.
Looking for some good feedback from you guys on the .243 90 gr and 7mm 150 gr in terms of load data. Spoke to a tech at swift this week and he told me they have their best results when seating AT LEAST 50 thousands off the lands. Anyone have any real life experience with reloading these? Usually it's recommended to be closer than that when trying to develop loads. I wonder if it because the jacket is so thick that you can't get so close due to some high pressure or something.
They also are all out of their 1st edition reloading manual and the 2nd edition isn't due out for several months as they continue testing products/powders.
different bullet manufactures usually give a direction on bullet seating depth that generally has worked for their shooters with their bullets. barnes x bullets are recommended .30-.70 off,nosler bt's usually .10-.050 off.
this is a starting point & there will be exceptions like this one.
bergers- most start .010 off & adjust in & out until they find the sweet spot,there has been controversy on jamming & non-jamming with bergers. some of my 308';s like .010-.030 off
my 6br's like bergers jammed - one @ .018,the other @ .015-neither likes the recommended manufacturer bullet jump's.
when playing with bullet adjustments always start low & work with a chrony.
