Never can have enough manuals.

[Peter M. Eick]

My sixguns is on the 3rd shelf. It is a signed copy.

The original print is in a grey book in the middle. Kind of neat to have a signed version.

didn't notice any of the older hodgdon manuals. see a later one. do you have a copy of the original rcbs loading manual? was a small paperback book with loading info and die set-up. got one when i first started loading in the mid 60's. nice collection btw. another interesting one is the alberts bullets loading info. they were a swaged bullet company years ago.

Nice collection, I noticed you have a selection of Sierra reloading books. I have the 1971 copyright version & maybe you can shed some light on a question I have pertaining to the 4831 powder for the 300 H&H w/180gr matchking HP bullets. I believe the powder was from the military(?) back then, but without a pre letter H or IMR in front of the 4831 I'm concerned about using these listings for todays IMR 4831 powder charges. Does any of your Sierra books give any information on the powder change to IMR 4831 & the loadings.

It's a common problem with the earlier manuals. IMR 4831 wasn't introduced until after the 1971 editions were published, so all of that data used H4831 (surplus powder packaged by Hodgdon).

That's the problem, I've got IMR 4831 powder but nothing for the loadings. If I remember right, H4831 was a bit slower than IMR4831 that's why I was asking if Peter might have the listings in one of his abundant newer Sierra Reloading books with the IMR loadings...

 

[Paul5388]

Speer #13 says 70.0 gr IMR 4831 with a CCI 200 for 3086 fps max load. Start load is 66.0 gr for 2853 fps. The data is the same for all 5 bullet shapes they offer in 180 gr, but you should probably use the start load and work up.

So, why is there a difference in maximum powder charge between the different manuals for the same caliber and bullet?

 

[Paul5388]

Different test equipment, bullet jacket hardness and core material, even for the same weight bullet. All of Speer bullets have the same materials, so it doesn't make much difference on the shape, but Sierra may use different alloys in jacket and core.

Sometimes the lot number of the powder used will make some difference.

Thanks Paul5388,

I'm going to try that load from your book, Hornady 3rd edition, Lyman #46 & #49 editions along with the Sierra 1971 edition have no mention of IMR 4831 for the 300 H&H. My NRA 1981 Handloading book does shows the 180gr remington bullet with 73grs IMR 4831. My Nosler #3 book shows the 180gr w/max 68grs IMR 4831. The rest of my reloading books are before or during the H4831 surplus. The last loads I used for my 300 H&H were 68grs IMR 4350 at +-2881 fps on my Chrony with my Winchester 70.

Since I've gotten older, I feel recoil a little more than when I used to so I've gotten my old Winchester 70 300 mag back out. I've got some IMR 4831 left & wanted to use it up. I had replaced my 300 mag in the 80's after many dependable years to a new XTR Winchester model 70 in the 300 Weatherby caliber, I wasn't to excited about the new Winchesters but I finally got the opportunity to have a 300 Weatherby without having to rebarrel my old 300 or to be forced to buy a Weatherby. IMR had just came out with a new powder, 7828, at the time there wasn't any reloading books with the 7828 powder so I wrote or called Nosler, Leupold sent me the data for the Nosler bullets & IMR load information for the 7828 Powder. I immediately started shooting out the factory loads & replaced them with my reloads with 86grs of 7828 & nosler bal tip 180 gr bullets & have never changed from that.
