Tell me what you think about my proposed load.
I have some Oregon Trail Laser Cast 240 gr Lead Semi-Wadcutter bullets on the way here.
I have a good amount of IMR-4227 and WLP primers on hand.
I am thinking of trying about 22 grains of the 4227 with the WLP's
Hogdon's website shows 240 gr LSWC Cast at 22.0c gr of 4227 with the Remington 2.5 primer for 1310fps. They do not show a starting load.
My Speer # 13 manual lists what appears to be a very conservative load for the LSWC for 867 - 947 fps. But none of them use 4227. However they show a 225 gr cast bullet with a loading of 21 - 23 gr 4227 going 1192 - 1329 fps. They list their jacketed and even the TMJ 240 gr using 21.4 - 23.4 gr 4227 at 1252 - 1340 fps. All their loads for 4227 do not indicate magnum primer. So, it would be the CCI 300.
I also asked Oregon Trail for their loading data. They sent me a list. But, none of the loads use 4227. However, Their loads, using WLP primers, for the 240 LSWC very clsoely resemble the Speer loads for the jacketed bullets comparing powders that both companies listed. Oregon Trail pushes the bullets anywhere from 1044 up to 1525 fps (using 2400)
So, I think I am in the ballpark. Anyone have any experience with this combination?
