So when ya see the shortages, and supply issues, happen a few times in prior yrs...learn from that and buy a lifetime supply of bullets you use, before the crisis hits. I have many thousands of Sierra 107 and 110 gr and many thousands of Berger bullets I use...bought cheap on sale, or free shipping. I have seen this crisis before and and acted early, remember 2019 primers were $22 per thousand...then they limited Berger bullets to 2 500 boxes...I bought 2 of the 8 500 count boxes available....everytime, a shipment came in, until I was fully stocked up. I use the Bergers in 6 Dasher for fine paper punching 2970 to 3020 fps ....and 110 gr SMK at 3085 fps in the Dasher for long range steel, and 107 SMK at 3132 fps with the Ball powder, and good accuracy, for that purpose. Might need the new .277 Furry ...neck it up...neck it down, ..think of the possibilities 80,000 PSI with the SS heads and we could push it to 83,000 easily and maybe to 85,000, psi all right next to your face. What could go wrong? A case full of Titegroup behind a 105 necked & trimmed to 6 dasher....do not try that at home, just kidding..Good thing dies are not available for the special SS case head, and neither are the cases widely available at $4 ea. Plus the company hasn't recommended reloading the high pressure cases. But I could make dies if I had the cases... I believe the sizing die needs a case ejector installed so ya don't mess up the 3 pc case, of SS head, Alum insert, and brass body, when sizing. How useful is it, really...then think of all the .277" bullets I don't have.
