First off, i am not new to reloading. no i dont know everything about it but i know what i am doing. I see people coming on here and asking about it so i figured i would give it a try since 4451 was a newer powder. if they were at then the others would be easy.
as for it being a reliable tool to use for people, the only thing reliable is what my gun does with my components.
second, i cannot find these loads for a 130 grain in a 260. i will take pictures of my books that i have to prove this. also, i went through the 260 rem thread to look for those loads and the only one i could find is the 4831sc. I have looked at the powders website for information, none of them are listed. i know how to look up starting loads but there isnt any.
for instance, in my books, they only list out 120 and 140 gr loads. so i am splitting the difference and giving it a try. as for the 42 grains wont blow your face off, imr-4064 has a max load of 38gr in 120 bullet. so if 4451 is similar than yes it might being 4 gr over max. not saying 4 gr over max is going to blow up but anything is possible.
if yall dont want to help out then thats fine. just needed a starting point but i get a bunch of assholes instead. its about average for par. mods can delete it.
