Would you pay for new powder listings in your favorite calibers? I don't see any of the temperature stabilized powders in 30-30 that I would think hunters might like. Ar-comp seems like a good fit. I'm curious about 8208xbr as well....

I’m stocked for 5 years with enough powder and primers and lead for pistol bullets. Jake at RMR covers me for 69 3GH in 223 and 124 MPR’s for 9 for the little jacketed I shoot. I already have my load workup done, I’m just duplicating the same recipe over and over and over. I don’t hunt and have no need to switch powders, so for me I would not benefit from a new manual.
 
I’ll probably buy it although I have the 50th, just cause.

Previously I had an old Speer manual and a P O Ackley manual plus bullet manufacturer manuals from Hornady and Barnes.

The PO Ackley 2 book set has some loads in it would give powder manufacturer’s lawyers heart attacks!!!

Anybody that fills reamed out chambers full of powder must have been a lil nuts, but not back then!

Reading the old(er) gunwriters is really something, particularly the handloader/wildcatters.

Most of them had no access to even a chronograph, much less pressure testing. They would just shoot more loads (add more powder) until the load/rifle shot well, or quit shooting well, then quit. If it was 10k+ over pressure (and many were) they never knew it.

There were some labs that would do pressure testing - E. Keith used a few - but were beyond the means of most.

I look at some of their loads from back then and shake my head. Some start loads are over max in the manuals today.

Yup. I try - real hard - to remember to include that caveat whenever I recommend a load to someone. "This is using non-pressure-tested data..." etc. etc. Yes, it's a book load and is using components still theoretically available today, at least in name; but, possibly in name only, and probably not much different than when the data was published except using better QC standards. We hope. The newest manuals tend to drop the oldest cartridges and abandon the oldest bullets. You really can't find good loading data in a modern manual for the .38 S&W. Yes, there's maybe a token listing, but it's dumbed-down to the lowest common denominator and is typically for modern, commercial projectiles which are undersized for the spec's. The new manuals have pluses and minuses, just like the older manuals, and they're all just guides providing what data they can, gathered using the best means possible, for the benefit of the editor's customers. The Editors typically being the maker of something related to reloading they want to show-case and sell. Not a thing wrong with that.
 
Anyone got their copy yet?
Curious about what changes/new info made it in.
Anything pertaining to powder coated cast bullets?

I just ordered a soft cover from Midsouth (on sale for $23.99) but haven't got a clue if it's even shipped yet.
 
I won't be buying it unless I'm able to flip thru the pistol section and see if they have more data than what was in the 50th, really disappointing how 75% of the 50th was rifle and the rest pistol and certain bullet weights and powders were not tested. For $35 I'm not expecting the 51st to be any better.
 
I can't wait for someone to get one in hand. I expect new cartridges to be in psi but updated data in common calibers like 9mm is kinda expected.
 
Anybody that has it, do they include W244?

I’m sitting on 5 lbs if that and currently going another direction.

why did I buy it???? Availability!

There are many people sitting on many different powders for that exact reason.

I'm sitting on a pound of BlueDot. I bought it (at WalMart, of all places) back in 2012-ish. I had never used it, and haven't used it in 10 years. I bought it because it was available when nothing else was.

Maybe I'll trade it off.

Shame we ain’t neighbors, I’d swap ya out of it.
 
CUP versus PSI chamber pressure.

I'll discuss Old Faithful -- 30-06 cartridge with 150 grain FMJ bullet. Pick your favorite powder, IMR 4064 @ 48 grains. Using same box of primers, same can of powder, same brand of cases, same box of bullets load 20, 40 or 60 rounds. Fire half of the bullets in a PSI device, fire the other half in a CUP device. Simple arithmetic will calculate a conversion factor to change between the different units.

I can hear the blather and exceptions starting already. Think of this in SIMPLE terms: slices of bread, how many eggs, how many apples, how much rain fell last night can all be evaluated to determine an answer. Looking at my Hornady manual, 56,100 psi and 50,000 CUP are safe loads. 1.12 CUP = 1 PSI . If pressure is in CUP, multiply by 1.12 to get PSI. If pressure is in PSI, divide by 1.12 to get CUP
Is this answer meaningful? Is this answer scientifically correct? Is this a sensible calculation? My answer is yes. An internal pressure was caused and measured. This is not a comparison between a dozen eggs, a dozen apples, or three loaves of bread. Internal pressure is pressure no matter how you measure it.

Sometimes, the cup is higher than the psi, but most of the time it’s the other way. You cannot accept it as a rule one way or the other.

I don't hunt either, but to me, just doing the same load over & over would get monotonous & boring,
and lead to paying less that full attention.
Not that I'm saying anyone else would.
But I know me.
Besides I think its GREAT fun to switch powders & see what happens.
I like accuracy & speed changes.

Take 38 Special, I've loaded like 10 or 12 different powders.
TiteGroup, Universal, Accurate #2, Accurate #5, W231,
Clean Shot, Red Dot, Bullseye, Unique, even did some +P with 2400.:what:
There's more, but I can't think of 'em off the top of my head.

So I like to stay on the cutting edge
