Thanks for all the help Alchemist!

Too all the gurus, based on the following load stats from this past weekend: Bullet: 180gr Nosler Accubond Barrel Length: 608 mm / 23.937 inches Case: Hornady (90gr H2O) COL: 85 Charge: 68.5gr S365 (Lot 81) Velocity: 2939 ft/s Bullet: 200gr Nosler Accubond Barrel Length: 608 mm / 23.937 inches...

Okay, can you please verify the attached load then? I increased the "Heat of Explosion" with 0.8% (from 3685 to 3714) as per lot Deviation (bottom of the tin / as also stated on the S365 WebPage for Lot 081). Also set the "Ratio of Specific Heats" from 1.239 to 1.241 as per the Somchem...

Can you please guide me here, I would like to understand the burn rate thing so I can properly / safely apply it in the future, Attached is a screenshot of my current load, I have not configured any variables on the Charge Window, except for "Ratio of Specific Heats", which is wrong compared to...

So let me share this weekend's data. Again, QuickLoad was not accurate, at all... In the attachment, you will see different loads for my 180gr as well as the 200gr Accubonds. I used QuickLoad to calculate the Velocity and Pmax based on my SomChem S365 being +0.8% deviation from the standard...

Thanks for everyone's input so far. I have surely learned a few things, although a lot of speculation and theoretical analysis was shared as well. None the less, I'm not that ignorant, for this weekend I will back off the loads a bit on the 180grains as well as the 200grains to see how they...

Maximum Pressure for the 300 Win Mag: CIP = 62,000 psi (4,300 bar) SAAMI = 64,000 psi (4,400 bar) Using my load data in QuickLoad, I get 62442 psi (4305 bar), so I'm just over CIP, and under SAAMI (screenshot attached). The only reason that the Pmax is given in red (and message DO NOT USE THIS...

I don't stare myself blind against QuickLoad Pmax Results. I use it as a guideline only, I have found it to give correct and incorrect results. I'm able to increase the charge because the cases have a larger internal capacity than the PMP cases used earlier. Work your way up from light loads...

So, a lot of load work done this past weekend. I changed to Hornady Cases with average internal volume of 90gr H2O, yes I tested all 100 cases I bought new. With the 200gr Accubonds, I worked my way up with S 365, I am now using 66.5gr and pushing the bullets at average 2900 ft/sec, 100m...

For the 200gr Accubonds, I bumped up the S365 to 64gr, now I'm grouping nicely at 2800 ft/sec. The 180gr AB still working properly with 66gr of S365, running at 3000 ft/s . All this in PMP cases, must say, they are not the most consistently weighing bunch. Getting 100 Hornady Cases to see if I...

So I shot my first batch of hand loads this past weekend, I used both SOMCHEM 385 and SOMCHEM 365 Powder on the 180gr and 200gr AccuBonds. My PMP Cases average at around 86gr H2O internal volume. I used QuickLoad to guide me with both powders. I loaded multiple charge batches of 4 bullets...

Hi, Anyone here have experience with compressed loads for the 300 Win Mag using SOMCHEM Powders?

The thicker walls also mean that less powder is needed to reach the same pressures as a thin wall case with slightly more powder charge. I see the S365 Powder have very similar properties as the S385, and less grains of powder needed, so this might be a good alternative. What would be the best...

Thanks for all the info peeps. The reason I'm considering a "Higher" Velocity Load, and not just settling for a more Practical (worry free) 2500ft/s is because of the shot distances in the areas I hunt. 250 meter+ shots are not uncommon on some big game (an Eland this time), thus I'm looking...

Hi, So I bought the "Reloading Powders - Ballistic Data Manual" from Rheinmetall Denel / SOMCHEM. Checking the load data for the .300 Win Mag for 200gr Bullets using S385 Powder, the Maximum Powder load is 68.7gr. This gets the projectile up to 2720 ft/s, I find this relatively slow compared...
