Default Any difference between h4895 and imr4895?

Normally use H1000 powder with Speer 120 grain bullet in my 25.06, can't find any powder locally, checked Speer reloading manual and H4895 is listed, have plenty of IMR4895, can I use IMR4895 in place of H4895? Thanks in advance.

Check Hodgdon’s on-line load data. They show loads for both powders with a 120 grain bullet in 25.06.

They are not the same, but close. My Speer #9 manual shows 120 grain spitzer bullet for the .25-06 using between 36.0 to 40.0 grains of IMR-4895. Velocity is from 2436 to 2692 fps. No pressure readings are given. This should be similar to your load with H4895.

H4895 is a Hodgdon company powder which was made to be a close copy of IMR4895 but they are NOT the same. Reloading manuals list them separately, so the best advice is to get a manual with recipes for the specific powder you want to use.

The powder naming and numbering system can be confusing. Even more so when the Hodgdon company bought and now produce the IMR line.

Some of the newer reloading manuals like Lyman's or Lee's and other companies' large books have sections on powders and their applications and burn rates. Really good to have a few up-to-date editions which include newer powders. Compare the loads suggested in one manual with the loads suggested in others.

H4895 is made in Australia and IMR-4895 is made in Canada by General Dynamics.

They may be close in burn rate but they are not the same powder.

IMR 4350 has always given me better results in the .25-06 than faster powders.
