As your loads show (once again), H or IMR4895 are great ones to use for "somewhat" reduced loads. You can take them down to 30% below max and they still work great. Actually, I only know about using IMR but H is so close that any difference is a non-factor.
46 grains IMR4895 under a 150 grain bullet in the 30-06 turns it into a .300 Savage at about 2600 fps. That one load - 46.0/150 gr. bullet, consistently produces some of the tightest groups in the four '06's I've used it in.
Same 46 grain load under a 130 grain bullet in the .270 makes that into a very accurate 7mm-08.
It's been a while but I used to load a .308 down to about 2000 fps with a 150 grain bullet and, you guessed it - IMR4895.
Nowadays most all of my shooting of anything over .25 caliber is done with those "somewhat reduced" loads and 8 pound jugs of 4895 occupy a prominent place on the powder shelves.
