This is in referense to my question about starting load for my 300 win mag. I was showen what hornady had for load data and the max they had was under what the min of all the other had. All my other ref including the powder company all state 72 gr for a min and between 75 and 76 for a max but hornady has 64.5 as min and 71.9 for max. anyone else run across this reloading. here is a link to my other question for ref

ya but this is quit a differnce. Hornadys max load is smaller then all the others starting load. I always hear that under loading a round can be just as bad as over loading a round.
That info I provided is out of Hornady's 4th edition. Additional photos. They used a Win Model 70.
man i just called a buddy and had him check his sirra ( spelling) manual and speer and they both came up with what i came up with. I game him the info you gave me and he said him manual shows those loads for a lot heaver bullet. Like around the 230 gr range. I'm loading for 168 gr.
I backed the camera up to show you I am not Full-o-chit, at least on this one. I am concerned about this, as I have been loading out of this manual, and even though I do not load this round yet, I do load lots of other rounds with the info in here.
Only showes IMR 4831 with a Max of 72 most accurate of 70 gr.
If right H4831 and IMR4831 are different.
Sorry
IMR4831 and H4831 are very similar in burning rate with IMR 4831 being just a wee bit faster. Usually by a grain or grain and a half less of IMR4831 equalling that of H4831.
If it were me...I would go with the data from Hornady. I am not saying they are the end all of experts, but they are a darn decent company. I do not think they would put out data that would jeapordize your safety or your firearm.
Mine does not show a 168 gr. only shows 165 gr. Mine is a 3rd Edition.
mine shows the same amount for the 167 as it does for the 165

Ya but i dont think speer, hodgdon, sierra, would either. I checked all three of them and they all state the same with in .5 gr for min and max load. the only one that conflicked the others was hornady. Kinda scary if you ask me. Hornady is way different then the rest.
IMR 4831 70 Start 75.5C Max(Not sure what the C meant)
H4831 72 Start 75.5 (No C on this one)
