[QUOTE="Wild_Bill, post: 274283, member: 4785"] Hi if you are after Carturio 189gr 7mm projectiles i have over 400 of them in my 7mm BSM with a Lawton 9 twist cut barrel they will not shoot i can shoot Sierra 175's and 168's and they shoot like stink but the Carturios wont shoot. I also tried the 162 A Max the first made it to the 600 yard target the next two turned to dust 10 yards from the muzzle. The case is a modified 270WSM case with the shoulder pushed back to give it a 370thou long neck then it is improved with a 60 degree shoulder. I was using 68gr of retumbo with CCI250 primers and am using 68.5gr H1000 with the 175gr Sierra Molly coated in a 32" barrel have not chrono'd it yet but it should be well above 3000fps i am thinking closer to 310fps it is my long range F Class calibre. If you are interested in the 189's let me know and i will count how many i have left and work out a price posted to you. Cheers Bill Australia [/QUOTE]
