Which one is better for the 22-250 w/ 50gr bullets, 1:14 twist.
Anyone here test to see if H4895 does really work in hot and cold temps, better than standard stick powders?

I call IMR and H4895 a toss up.

While I agree with Ramrod's post, I wouldn't use either of them in the 22-250....look to H-414 or H-380 as best powders to use.

I've used lots of both 4895s in 22-250s, they both shoot fine. However H4895 has smaller kernals of powder than the IMR. It will, most often, throw more accurately and uniformly from powder throwers if you don't weight each charge. The "extreme" H4895 does work as advertised. I only lose about 25 fps from 70 degrees down to +10 degrees. The IMR 4895 loses a whole lot more.

Spot on VD. If you get a chance do yourself a favor and try DP 85 and or Dp 86 in your 22-250. roger

I would agree with that except he asked for something that would work in hot and cold temps. Not saying that 414 or 380 wouldn't work, just that in my experience they are both to sensitive to temp. change to work up a "year around load".

Boy I really have gotten boring with my reloading. I've been reloading for 35+ years now. From 222 to 458 and I have never worried about hot/cold weather loads. Yes I have tried loads in the hot vs cold. I have just never seen some of the huge differences that others say they are seeing.

For me if my load isn't safe in the hottest and coldest weather it will be used in then it "just isn't safe".

I've never shot a 50gr in my 22-250. I have used the 4895s in many other loadings. Since I weight every load how it throws is really not an issue to me. For my 52s I tried 4895 along with several others and now use 2460.

As of now, I am using 36.3 gr of IMR4320, Rem. cases, Fed 210M primers, and Nosler b-tips, best load so far.
Before the rebarrel, I used AA2460 with great results.
New barrel hates WW cases, H380, M Kings, Hart Match, Vmaxes, standard & BR primers.
I'm thinking that the 22-250 likes faster powders..... thats why I might try H4895 or go back to AA2460.

I've never had any load that I've worked up with H-380 or H-414 be unsafe in any temp. extreme I have shot them in neither. But if accuracy is the issue, and extreme accuracy normaly is with a 22-250, I've never had any luck with working up a load with neither powder that would give satisfactory accuracy year round. Not where I live anyway, very close to the original poster.

Nearly locked up a 22-250 with a H380 load worked up in 30 deg. temps when I tried it the next July in 95+ temps. I quit buying H380 and H414 when I saw how dirty they were compared to the stick powders I was using. May not really make that much difference in most shooting, but I'd just rather have the stick powders.

H 4895 may be one of those extreme temp powders.. but big deal to me...

My problem with H 4895 is it is finicky... a load of x amount of grains may be a real tack driver.. then you increase or decrease a couple of 1/10s of a grain and it will start throwing shots all over the place...

IMR 4895 is much more consistent... its accuracy does not have violent swings like H 4895.. doesn't mean H 4895 is a bad powder, there are just a lot of others that are more consistent and do a better job....

I find IMR 4895 very consistent in a 22.250.. moreso than the old standbys of H 380, or H 414 as used as examples above...

I burn a lot of H 380 and H 414 especially.. however they just perform better in other calibers in ratio to other powders, than they do in the 22.250.. once again, across the board...

My favorite powders for the 22.250 are IMR 4895, Varget, RL 7, IMR 4064 and H 322... RL 15, W 748, BLC2 all get very honorable mention...

all work well with bullet weights from 40 grains to 80 grains...

When H 4895 shines, it does so quite well.. but that can quickly turn to suck... by just small variations in the charge weight.. that is why I don't give it an endorsement...

IMR Powders are my first choice in 4895 and 4350

Neither one !. Both are equal. I know what the books say so what . Shorter cut is the H4895 which will meter slightly better .

So many people are under the misnomer that Hodgdon's manufactures powder . Wrong !.

If it's cold or hot temp use a temp stable powder such as Varget or Bench Mark .

Personally I would use what ever gives the most accuracy in any particular weapon !. Nobody that I know has that one figured out for someone else's weapon . Above listed loads are good starting points .

The fastest method I know to check loads is start in the middle of the Data books . Work up and down .5 grain maybe 10 rounds each . Bench shoot the weapon see where your particular weapon is going so to speak . If hotter looks best work upwards if lower is better than work downwards . A Crony helps only in knowing the velocity of the load , can't say they do much for accuracy just my $.0025 worth of 40 years reloading .
Mine prefers H335 H322 BL-C2 ...
