I have started working loads for my .260 LRP and things are coming together. I am using 140gr VLDs and 142gr SMKs, topping H4350. I am having a hard time grasping why the loads are so different for 2 grains in bullet weight. The bullet design is so similar. I really want to use the VLDs but the SMKs are able to be pushed so much faster.
Hodgdon says 39 to 42gr of H4350 for 140gr bullets
For the 142gr SMKs its 41.5 to 44.5gr
I am sure RC will have the answer to this, anyone want to weigh in and give me some insight as to how they come up with this?
