Default .243 win load question and powder question

Hey, I am still a novice loader, but I have a .243 win that I am loading up sierra 55 gr for. I am out of my usual powder (IMR 3031), but I was see that you can use H4350. All I have is IMR 4350? Is there a load for that? I don't think I can replace H4350 with IMR 4350 because the burn rates are different.


I was also given a pound of H570. I load for .243, .270, and .338? Can I use this powder with any of those?

Thanks.
-Brandon

Don't the powder containers have caliber recommendations on the label, especially the Hodgdon?

Do you have reloading manuals to get load data? You don't want to go around swapping out powders just to experiment; that can be very dangerous.

Be sure to do as much research as you possibly can before you get deep into reloading. I am new to it also, but I am well-researched. I do WAY more reading than I do actually loading.

The IMR 4350 works very well in my .243

And your correct the H4350 is NOT a replacement for the IMR4350. It is close but not close enough you can use the same charge weights.

Since you are a novice reloader, you need reloading books. They will always answer your questions concerning the various powders. Ken Waters writes a very good book on reloading. I have never heard of a 55 grain .243.

Default .243 and any other cartridge

Never, ever, exchange loading data because powders have similar burn rates! Burn rate charts are not reliable and just the size of the case alone can rearrange the chart order for your particular firearm. Stick to published data.
I've loaded .243 for a long time and it is one of my favorite cartridges.If you ever get the chance,and like light bullets,try 68 gr. Berger bullets. If you E-mail Berger,They will send you loading Data for their bullets and your powder.They seem to be great people./They sent me a load for Reloader 19 and the above bullet.....very accurate using their minimum charge. I thought the powder might be a little slow for 68 gr. bullets but it shoots very well

I don't think H570 has been around for QUITE some time (you sure it's not H870?)

H570 was a large case magnum power way back in the day.

H4350 and IMR 4350 are NOT THE SAME POWDER.

To Lon IMR powders don't have use data on the can that I know of.

You are going to be hard pressed to find any kind of load data for that H570. The 570 would work in that 338 win mag I bet but Like a few have said Load data is what your missing.

Yeah, that's why I said "especially the Hodgdon." Couldn't remember if IMR did or not, so I used the word to denote uncertainty. Thanks.

Thanks for the replies, I did a little more digging and discovered that H570 production ceased in 1979. I am not sure if the powder is any good, but the can it came in is in great shape, perhaps I will find a place for it on the mantle. I don't want to mess with it if I can't get any solid data.
