Hey all I'm looking for some Quickload request help, I have a 270 win a bunch of 130 interbonds, looking at the Hornady manual and the Nosler manual there is quite a different charge rate on the 130 bullets, I get they are different metals, different shape etc. But it's up to 4-5 grains difference. The powders on hand are Reloader 17,19, 26, Hunter, and Magpro. Hornady brass, 24" barrel. Please Dr Mike or some other kind soul please give me some numbers or advice. thanks and happy shooting and hunting.
