Im trying to work up some managed recoil 100gr .270 loads. I have some IMR4895. Every thing I have found on the IMR/Hodgdon website about IMRyouth loads, it shows the H4895 Data. Basically when I click the IMR Youth load data tab it shows data for H4895.
I've been looking online and most threads say load data is not interchangeable, I tried calling but they are closed now.
Any one have any experience with this? Im getting ready to make a few loads for my daughter to try, and I want to make sure I'm safe.

Any help would be appreciated.

Thanks

I'm 99% sure IMR4895 and H4895 ARE NOT the same powder but someone will be along soon that knows for sure.

H is a hair faster and more temp stable.

I have shot a lot of deer with 270 130 gr 50 gr IMR4895 22" barrel 2875 fsp. That is a wimpy load, but it kills them out to 500yards.

Hodgdon touts H4895 as the slowest powder that is safe to download. IMR4895 is a couple places slower on the burn rate chart.

I'm not sure that there's anything special about H4895, or if it just happens to be a good burn rate for reduced loads.

DDawg,

Substituting IMR4895 for H4895 in a reduced load will not be a problem. I do it all the time in .308 for 200 yard match loads.

Thanks,
That's what I needed to know!

That being said--how does the substitution work across the board on standard, or hotter, loads??

Would not suggest you do it for full power loads. The two powders react a bit differently at high pressure.

Substituting IMR4895 for H4895 in a reduced load will not be a problem. I agree, having used IMR 4895 for reduced loads in cast and jacketed in 30-30, 30-06, 308, long before Hodgdon's reduced load data was published.

270 130 gr 50 gr IMR4895
That load is 3 or 4 grains over max in my books.

www.hodgdon.com agrees with you. All IMR powders but 8208 are temperature sensitive, and the reason that I personally do not use IMR powders. It won't be an issue with reduced loads, if you can get the consistent accuracy that you want.
IMO, it's hard to beat H4895 in that burn range.
