IMR has their new manual on their website.
http://www.imrpowder.com/

It has data on the new Remington Magnums and some other new ones like the .270 WSM and .450 Marlin. Unfortunately, the data is in PDF format and you can't do a quick lookup anymore. BTW, Adobe Reader 6.0 is another case of bloatware. If you don't need the lastest version, don't download it.

Hi, Gents:
The new IMR manual is a mess alright, but the 7x57 and .35 Remington are still there, on page 48 and 50. They did dump most of their Weatherby data.

They're posting their latest data in PSI starting on page 51. The older data is still in CUP, and starts on page 47.

I :mad: PDF files.

Hi, Gents:
I can't wait to try that new 3895 in the .35 Remington either. It's in the Contender data in the Handguns PDF.

Actually the .44 Magnum loads with the slow rifle powders is a fairly good illustration of why there's an optimum burrning rate for each cartridge and bullet combination. The .35 Remington data is better, as it has powders that are too fast as well as too slow.

I wonder why they've speeded up 4230 to the equal of 4064. That leaves a big gap between those two plus 4895 and the slower 4350. It means the old standard .303 British 180 gr. load isn't usable with new 4320.

There's a rumour floating around the net that IMR might start making 8208 again. The original H322 was surplus 8208.
