If IMR4198 has actually become H4198, I bet that Hodgdon's lawyers were involved in the entire decision making process in anticipation of the few who might see a lawsuit as being a good thing concerning it.
As Bill stated, a simple change to reloading data to reflect the change in the powder, whatever its called, would probably suffice for everyone but some dude who wants his old green short grain H4198 back or he sues. JMO - BCB

Correct BCB. These companies are not going to just throw something out, with a little CYA. If they did they would be really silly or stupid. We will be just fine, with what they end up with, if a person still wants to use that powder, just work up loads, as we always do for our rifle/s. That is why we reload, as you and I well know. Part of the fun.

The difference we see (in the lab) between the two 4198's is pretty close to the same difference you see with lot-to-lot variation.
Just like H110 and W296 are the same powder poured into different containers, They are doing the same with 4198 to save on having to stock two different formulas. W231 and HP-38 are the same and W760 and H414 are the same. This is not a new idea to them. No suit would have standing since anyone who failed to shift the load back down accounting for a new lot number (a well known and published practice though often ignored) would be the cover.

You might want to look around on this site:
http://www.ilrc.ucf.edu/powders/samp...&powder_id=372 It is an FBI Forensics website on the analysis of gun powders. They showed three different variants/lots of H4198 with slightly different lengths and powder coatings. It is very technical, detailed, not easy to navigate, and it is a very large database for most of the powders available. It has a wealth of information if you are interested. |

i have three different variations and 2 colors (black and greenish ) of 4198 as well as 3 diffrent lengths. i use the fastest data published for all three and have never had a problem.

Powder that looks greeny yellow/gold is from ADI, they use that unique coating color.

This and lot to lot difference's
is why I never ever load to the max. Except when trying to find the max for a new gun. Then I step it up a bit at a time til pressure signs and chrono readings show where to stop. Only time I've ever blown one up was that NEF in .17 VR. Stepped up .2gr, then .1gr. No sign of pressure at all. That one .1gr blew it up after ten shots of the same charge just below that. After than I cut it back .5gr. I don't drive my vehicles wide open, I don't understand anyone that would drive their guns to the max either.

Years ago, I had lot #2500 of RE#7. It was the normal light coloured short kernels, but there was what looked like IMR 4198 black sticks in it. I bought another can of lot# 2500 RE#7 as a cross-check and it was the same.
Shot the same ballistics as any other RE#7 I had used in my .458 and .17AckBee.

I am kind of glad that I have 4 lbs of the same lot of H4198! L461 .222 loves it! I guess that is all I will use it in now.

In my opinion, the powder manufacturers blend their cannister grades to make specific levels/blends of properties. That is what becomes a cannister grade so it can be consistent between cans you can buy. I have seen RL-7 with scattered grains of both red and green grains along with the grey grains. Any time you get a new cannister, it is Smart to back the charge off a bit, test and load back up to the level you require.
