I cannot precisely tell you off the top of my head.
IMR 4895 is essentially the original military powder for the 30-06 ball ammo used in the Garand.At first glance,it would seem a good choice.
However,my little yellow caution light comes on over the Barnes TSX bullets.
Its not a red light,its a caution light.
IMR 4895 is a good 30-06 powder,but it is on the quick burning side of the spectrum.
The Barnes TSX bullet is solid copper,isnt it?If Iunderstand correctly,those are a little harder for the rifling to engrave.So,maybe,they are more resistant to moving down the bore.A quicker powder like 4895 may not like that.
I'm going to the trouble to explain because there are better approaches.
I think if you go to the Hogdon site you can get some IMR data.Maybe they will list your bullet.Try the Barnes website.
In any case,you need tested,published data for the recipe you use.
Once you find load data for your bullet,you might see how IMR or H-4350,and REloader 19 compare.
You also might look at Grafs,Midway,and Natchez websites.They have a little more inventory.
If you don't have a loading manual,get one or two.I like to have one from my bullet MFGR,and my powder MFGR.
Most all of the loading manuals will step you through the process.
Good luck!
Edit: I did some research for you.This will tell you what you need to know.
Data!
