On the one powder poll I see that "H" beats IMR. Just wondering what the scoop was on that. Haven't been loading 243 too long, tried IMR with good success. Do I need to try "H"? More versatile? Measure better?

Personal preference more than likely or most are using the Extreme powders which are supposed to be less bothered by changing temps.

Myself, I use them both plus a host of others and haven't noted a whole lot of differences with the temps we have round here.

IMR 4895 and H4895 are similar but not exactly the same. I get good results from both in my 30-06 Garand loads but the powder charges are not the same to achieve the same velocity.

I prefer H4895 but for no particular reason except that I have loads worked up in several cartridges with H4895 and not IMR4895. I don't feel like working up new loads.

As I said, 30-06 is the exception.

Well I was just going to stick with IMR but after seeing everybody using H I was worried I was missing out. Grass always looks greener kinda deal.

No its a personal preference type deal - which is probably a result of which reloading manual listed what - when the reloader was first working up a load.

H4895 is supposed to be faster than IMR4895, but my surplus bulk IMR4895 is fast, it acts more like H322.

I have been using IMR4895 since my first reload ~13 years ago, but my next reload will be H4895, to get some of that temperature stability.

If you have an accurate load run with it. My main reason getting into H-4895 was using the Youth loads off Hodgden's site when my then 3yr old grandson decided he wanted to shoot himself a hog, and wouldn't take "your not big enough" for an answer. I worked up some light .308-125gr loads, and after several months of weekend practice, two weeks before his 4th birthday he dropped his hog.

I had the IMR sitting on the shelf but was hesitant to use it since I didn't have specific data for it with reduced loads, and with the kid using them I wasn't taking any chances. I've used the IMR for some loads in several different rifles, and found it to be quite accurate. The Hodgdon powder however is reserved for the light stuff as I have two more grandsons will be out there with me in the not so distant future.

That is a great picture! i recall the anti's getting a hold of a photograph of a six year old that killed a snake and they raised a ruckus over it claiming that she was being raised or trained to kill. I thought she was being raised as a human being doing what we were designed to do. That there is a fantastic picture for submission to the various hunting publications.

In my limited experience, IMR4895 and H4895 are very close. However, a pet load developed with one of those powders might need slight adjustment if you switch to the other. They are close but they are not exact substitutes for each other.

I have had different results with IMR and H4895. Different powders for sure. I have about 8 lbs of H4895 that I use for the 30-30 and .303. I also use it for reduced loads in 30-30.

For the 243 win. you want IMR 4350, IMR 4831, or H4350. IMO. :)

Yes I started with H4350 and Varget. Thompson Prohunter. Seemed like very narrow range with those. Went from too little to too much real fast.
