Jordan,
Yeah, I can usually get Partitions to shoot to the same place as a similar-weight "affordable" bullet. Often I start out devleoping loads for a new rifles with Sierras of the same weight as the Partition (or whatever more expensive bullet) I intend to use, then just switch the bullet after I find the right load. More often than not the Partition shoots accurately and to the same place with the affordable bullet, and then I have a sight-in, practice and "deer" load, saving the Partitions for heavy lifting.
As a matter of fact even my double rifle in 9.3x74R shoots to the same place with 270 Speers and 286 Partitions, using the same powder charge of H4350.
