Re: Fire-forming 280 Ackley Improved from Lapua 30-06?
Yes, Lupua seems to be the best and only in 30 06 now a days. But before buying 06 and shooting until it stretches to lenght, check the lenght of the 270. Still no Lupua but yes to Nosler or Norma.
Necking up .10"is less of an adjustment than the .20" down from 30 06. Other options are to get any brand ready to load then weigh very carefully and take the closest to a particular group. Some fill shot cases with water then weigh to check volume. The extra mass of water shows more clearly the volume of each case. Volume is the key to consitent reloads not brass strenght. With this method i acheived .25" 100 yard groups out of a 14" Contender in .223 .
Best to clean, then resize ,then trim. Careful to find a FIRE FORM load reciepe. Shoot. Now reload...good...do it again to expect your best accuracy.
I have two .280's and am always ready for a larger caliber challenge. It always spanks a 7 mag without the slap in the face.
