From those that use it, how is its lot to lot consistency.

i've found it to be very consistant

Very consistant.

Consistant I'm not sure. I bought one 8 pounder because it was suppose to be the 22-250 go to powder? Well it doesn't deliver the Hodgdon advertised MV for 24" barrel in a 26" barrel. I've gone to IMR 4895 and Benchmark. They produce higher MV and better accuracy.

Problem with H-380 it is temerature sensitive. It is not one of Hodgdons Extreme powders meaning it has a higher sesitivity to temperature changes. Ya get a good load developed at 60° and at 40° temperature has a greater effect on the load than other Hodgdon powders.

While I agree with J Johnson about its use in the 22.250 and not being the "Hero' powder it is claimed to be, it sure seems to like to be full in 223 cases, especially with the heavier bullets..28 grains is my usual load, regardless of bullet weight up to 70 grain bullets..

As far as temp sensitivity...unless your are talking 30 below hunting in Minnesota or Alaska, or 120 degrees in Arizona or Texas shooting prairie dogs, I wouldn't get all hung up on it..

It's capable of some amazing accuracy in the 8x57

I use H380 in my .22-250 because it produces the best accuracy. Since I'm shooting a short-barrelled M70 Featherweight, high velocity is a relative thing.

Have used it with great success in two .30-06 rifles too.

I have had excellent success with H380 in the .22-250. I have recommended it to friends who, when they tried it, had good luck.

I am beginning to believe that if you shoot a 52-55 grain bullet with a relatively hot primer (like Winchester) and around 38 grains of the stuff, it will shoot in nearly any .22-250. It's almost to the point that I would say that if it doesn't shoot in your rifle at about those loads, you rifle is not going to be a keeper.

I beg to differ, because my same 22.250s that don't shoot H 380 all that well, shoot very small little groups with Reloader 7 and IMR 4895... and that includes 4 different rifles..

I have to whole heartedly agree with you. H380 has been a very ho hum powder in my 22-250 but IMR 4895 (which I may add is listed as the most accurate powder for 22-250 in Nosler 4) has shot faster and more accurately than said H 380. Then there's always Benchmark which beats both of them velocity and accuracy wise in my Winchester Heavy Varminter.
