30 maximum load data ?
does anyone have any? I have a bunch of speer TNT I want to shoot. Any data would be appreciated. I was thinking accurate 1680 or maybe 4227 or rl7 Thanks, Bruce

Re: 30 maximum load data ?
Load data for the 30 Max is scarce to say the least. Since the 30 Max has a greater case volume than the 300 Whisper / 30 BO, I have always used a "middle of the road" load from 300 Whisper data as a starting point. I then work up my loads from there.
My favorite load for my 30 Max is 168 Sierra MK and AA1680. I haven't tried the other 2 powders you mentioned.

did the 1680 burn clean for you ( any granules left in the barrel ? ) so to speak. In using a very light bullet for 30 cal just curious as may have to use a faster powder. Thanks, Bruce

Bruce, I'm getting old and CRS. I generally don't worry about unburned powder as long as the accuracy is there.

I use 20-21 grains of 2015 in my 270 Max with bullet weights ranging from 115-140. Accuracy has always been reasonably good. Yes, there are occasionally some unburned grains.

Re: 30 maximum load data ?
Would anyone explain what the 30 Max is to me?
I’ve been an avid shooter/reloader for 4+ decades, but not familiar with the wildcat.
Parent case, case forming, and any sort of load data (or where to find it) would be much appreciated.
Thanks in advance.

Re: 30 maximum load data ?
I think the 30 Maxi is a 357 maximum case necked down to 30 caliber!! I have never owned one, but did own a 270 maxi! Very,very accurate!! Wheelgun
Re: 30 maximum load data ?
Thanks, I assumed it was based on the Maxi case, but wanted to be sure.
I “think” it was mentioned elsewhere that a 300 BO die was used to form the case, but again I’m looking for any info pertaining to the cartridge because I might opt to use it in an RPM pistol.
I’ve been unable, so far, to find any drawings or case dimensions.
I appreciate the help.

Re: 30 maximum load data ?
If you go this route, you will need to anneal the 357 Max case in the area that will be the neck and shoulder of the 30 Max. It's a rimmed case, so it extracts nicely from a TC. The cost to convert a bolt gun to it gains nothing over a 30/223 cartridge that is loaded down a bit. We shot in Brazil about 20 years ago, they were necking down a 357 Magnum to 30 cal. Cute little bugger.BoredinLC wrote: Mon Sep 11, 2023 8:29 pm Would anyone explain what the 30 Max is to me?

Re: 30 maximum load data ?
Thanks… Were dedicated dies used, or was case-forming and loading done by using a common die set with the Maxi parent case?
One gentleman thought the Maxi case was simply full-length sized in a 300BO die to form and reload…. Does that sound correct?
