    Hey guys I picked up some imr sr 4759. But i can't really find data with it why is that? I'm loading my 06 with 30 gr of it and it do it job great! But I'm thinking of trying it in my 22-250 with less powder of course. Anyone ever try it before?

    It is one of my "go-to" cast bullet powders.As mentioned in Txhillbilly's link,you need to be aware of pressure curve.....which is one part of it's charm with lead.

    It wouldn't be on my list of powders for reduced loads for jacketed fodder......ain't sayin not to,just think theres better powders.

    With a 22-250....I'd be looking/researching on trying to reduce throat temps?I use the classic H-380 load in my "250" and just be careful with rate of fire.Good luck with your loading.

    Ya so far I'm liking it in my 06. but i don't think it would give me the velocity I want with the 250 that Hornady superformance or imr 4320 dose.

    You can contact the manufacturer and most of them will send you loading data brochures free or very low cost. My FFl dealer had some he gave me free of charge. Also, most them have websites you can access
    just go online and start digging for info.

    4759 is also an excellent powder for heavy loads in .38 special.
