IMR 4895

It’s a good powder for that range of bullets but if you’re talking about an extruded powder then I like 4064 better. Both are a PITA to meter and if you’re going through the trouble of doing it you might as well go with 4064, I’ve found it to be more accurate than 4895.

I got 32 pounds of IMR4895 when I started reloading over 20 years ago.

I am mostly using IMR-4451 and some IMR-4166 right now with coatings for temp stability and Copper fouling.

I WISH IMR would put those coatings on an IMR-4895 speed powder.

Try 41.5 grains w/the 175's and 41-41.2 w/ the 185's.

I have fired more than a few thousand of the 175's and 41.5 of IMR4895.

The 185 prediction is a best guess based on past experience with 180's and 190's.

I finally moved to a ball powder for my reloading. I use AA2520 which has the burn rate of 4895. I've settled on 41.5 grains in a military case using a 178 hpbt. I can throw charges on tge money 95% and the other 5% within .2 of a grain. I loaded 500 rounds a couple of weeks ago in about 2 hours. Now some are going to come along and say its temp sensitive and it is just as is 4895 but neither are a big deal as long as you are not at maximum charges. You just have to keep good dope, you know? Like we had to do in the old days...

IMO, temp sensitivity has been way over emphasized...especially for a 308.

ALL powders are temp sensitive once the temp gets above 80*F. As long as you aren't running redline loads, you will be fine for most work to 800 or beyond.

Accurate 2520 is a fine powder, it meters well in my Dillon.

Pros:
-Typically available
-Mid-range cost
-Suitable for wide range of bullet weights
-Perfect burn rate, case fill, etc for .30-06 M1 loads
-Great burn rate for .30 cal semi-autos
-Meters decently...far better than 4064 on even a modified chargemaster

Cons:
-Not a stand-out in any one area
-(personal) I have gotten 4064 to shoot better, for the most part.
 
I got tighter grouping with 4895 on my 175 SMK 41.5gr than my varget 43.5gr. That’s just my input I’m still on hunt on a good load for 4895 load for 120 gmx lead free tip(6.5 creedmore) 18inch barrel piston ar10
