    I've got a REM 700 24" factory barrell, Choate varmint stock, 6x20 Vortex Viper, and a really lighten trigger. I'm working up a load with H4350, 180 grn accubonds. Anybody have any experience with H4350 vs IMR4350? I use them one antelope, deer, and elk in varying conditions from mid 70's down to about -30. I'm looking more for consitancy at distance vs speed.

    While those powders will shoot 180's out faster, I think IMR4064's going to produce the best accuracy, if accuracy's what you mean by looking more for consitancy at distance vs speed. That's the powder that was used with 180's in the '06 when it was "the" round to use for high power competition. And the IMR powders tend to have better lot to lot consistancy than the H-series versions.

    I've used plenty of both. I will second the use of IMR4064 with the 180s.

    3 hunters on a bear hunt, all 3 took 30.06s with handloaded 180 bullets. All 3 were pushed by IMR4064 with no shortage of killing power. Naturally I'm describing myself and 2 buddies. The bullets were 180 TSX, 180 TTSX, and 180 AB.

    There is certainly nothing wrong with the 4350s. They are near perfect in the .06. One of my best loads ever is with H4350 in my 30.06 pushing the 168 TSX. I have taken a few mule deer and a ton of whitetails with that combo.

    I also have many loads worked up with IMR4350 and I use a lot of that powder as well.

    Of the 2 you mentioned I'd use H4350 accuracy, ES, and SD are neck an neck with both but the H gives me almost 60fps more velocity. But as mentioned you can't go wrong with 4064, also Imr4895 and H414 work pretty good. I even have a 165NBT load with H380 that shoots great.

    I reread the OP. Looking for consistency v. speed? Look no further than IMR4064 for sure.

    And, if you're looking for good accuracy at the longer ranges, stay away from ball powder. Lake City Arsenal snuck some in their match ammo some years ago and while it did ok at 200 yards, at 300 top shooters began noticing it didn't shoot quite as well as extruded 4895. At 600 yard and further, it was pretty bad. Fortunately, the folks at Lake City Arsenal knew it wasn't all that great and ball powder was never loaded in National Match lots. Ball powder's never done well in accuracy games by folks capable of shooting the top scores.

    On my bull elk tag using 30-06 I use H-4350 with 180gr bullet and I'd use same load if I drew buck tag same season.

    I have another 30-06 set up for cow elk tag and I use H-4350 in that rifle.

    I drew buck antelope tag for this year not sure what rifle I'm going to use.


    I've tried few other powders and have gotten equal accuracy but H-4350 gave little better velocity in my rifles and I've had the cow elk rifle down to -27 the other 30-06 had down to 15 below. Was lucky got my elk,buck and antelope draws didn't draw bear tag.

    Well good luck

    I have used H-4350 in several different rifles ranging from 270win to 338wm. it has always produced great accuracy. It will give top velocity at max loads but very few of my rifles get great accuracy at max. With H4350 I usually find a sweet spot about 75 to 100 fps below max velocity and also get very low ES. Great consistency across changing temps too.

    On the flip side if you ever decide you want a robust powerful load that is accurate and may certainly be your top velocity producer, you can likely stuff as much Reloder 22 under a 180 bullet as you can put in the case. My past loads with that powder are compressed but man that 22 sure pushes those bullets out fast. I had no issues whatsoever with accuracy or change of impact when the temps varied. Lucky I guess. Re22 one of my favorite all time powders.

    Agreed. 22 has always been a top performer.

    What velocity at what powder charge (generally) are you achieving? Primer?

    From my old data book looks like the following:

    180 btip, 61.7 gr Re22, 2799, 2789, 2791, 2798

    that is with 210M primer

    I have not chronographed my newest loads with Re22 and the Barnes bullets but I'm using the 215M primer with almost the same charge. From range time and targets only, the Barnes bullets are flying flatter out to 330 yards which is the furthest distance I could shoot along side an alfalfa field in Grant Co. KY.
