Giving me Hell! Login/Join

For all you guys who are giving me HELL for shooting 83 grains of 4320 in my Lott, and wonder where I got such a load (since it is well over Hornady’s max), try these on for size:

In my Ruger 458 Lott I shot 83grs and 84grs of 4320 in the Lott with the 450gr and some 500gr.. The X bullet was fully petaled and stopped under the skin of a buf in Zim of 04.

With 500 grain bullets, I like 82 to 84 grains of IMR4320 in the Lott. F215 primers.

I had one rifle at 85 but most are max at 84 it seems...David Miller used 84 and so did G. Sitton as I recall..Jack Lott used IMR-4320 and 85 grs I have been told......I even know of one rifle that used a good deal more than 85, I shot it a bit and just couldn't get used to the idea, though all seemed fine and cases lasted 5 loadings, so I cut back to 85 with it and it was a velocity race horse with its 26 inch barrel...

A friend of mine gave me a copy of a letter today, written in 1993 by Jack Lott,to a hunter in Tx. asking for .458 Lott loads.
These loads were developed with Lott by David Miller of David Miller Rifle Co. one of the finest custom smiths around. Lott and Miller were looking for a load that would reliably give 2300 fps with a 500 gr. bullet in a 22"barrel and would not develop pressure signs in high heat. Mr. Lott admits that you can get over 2400 fps, but states that 2300fps gives more than adequate penetration on Cape Buffalo and Elephant without sticky extraction. These loads used reformed Winchester brass, 500 gr. Hornady solids and soft points. It is interesting to note that Mr. Lott talks about his reasons for developing the .458 LOtt. After being smashed up by a wounded buffalo in Mozambique that he had hit twice with a .458 Win and then several times with a .375 by his pro, and a few more hits with the .458 for a total of 8
bullets, he decided something with more penetration was needed. The powder used is
IMR 4320 with a Federal #215 mag primer. 22" bbl.

83.0 gr. = 2202 fps.
84.0 = 2308
85.0 = 2330
86.0 = 2355
Case length o/a = 2.800
O/all loaded length = 3.600
Bullets were full crimped


I could easily quote at least half-a-dozen more off this board that use 4320 at greater volumes than I did. ONLY after four loadings when my primer pockets became loose (that’s an understatement), did it become obvious that 83 grains was too hot for my rifle. There were NO visible signs that there was ANYTHING wrong with this load, I even measured my belt, as was suggested, and found out my expansion was EXACTLY .005, which is within limits.

AND, until it was pointed out that Hornady lists 73.5 grains as its max by some of you, I had no idea that they even had the Lott in their manual. I thought Barns was the only published manual that listed the Lott (and Barns info does not extrapolate well to other bullets).

Sorry for the rant. But I don’t like being fussed at (it’s a Southern thang). Wink

Yes and no! I worked up from 80 grains. Pressure signs did not come until later.

GAHUNTER, personaly I think that as far as their Lott load data goes, Hornady is full of bull. They have a lower max load for the Lott and a slightly higher load of the same powder/bullet combo for the Winnie. They did not put any effort in to developing their Lott data.

I will continue to use 500gr loads with IMR-4320, up to 84.0gr. I get around 2275fps at 84.0gr and Hornady's FMJ and soft points.

I have not seen anyone else who has posted anything about loose primer pockets with these loads. I am more suspicous of out of spec brass, than excesive pressure. The factories do not always get it right every time. Even though they try very hard to do so. I have had factory ammo with no powder in the case. Bulk brass that had some pieces that didnot get trimmed, etc.

GA--Here is what is happening in this
whole process.. Those hotter loads used
are loaded by those that in most case
load 2-3 times and discard.So it's a
choice of what you want.As far W748 goes
I can get 93 gr in case I have here.Not compressed but shaken down by tapping
it on table.Using Hornady 500 gr.You
should be able your get needed velocity
with that.Ed

Hog Killer,

I thought you were full of it when you wrote that Hornady allows more 4895 powder for the Win Mag than for the Lott. Then I went to the gun store and looked it up for myself, and, low and behold, you are right! In fact, there are a couple of powders that they allow more of in the Win mag than in the Lott.

To quote the great Desi Arnez, "somebody's got some 'splainin to do!" How in the world can a cartridge with more capacity, firing the same bullet, be allowed less powder, and be rated as faster. Using the laws of physics, this is not possible. (unless maybe their test rifle has an undersized barrel. However, it seems like the muckety-mucks at Hornady would have caught this inconsistancy and tried a different rifle)

Someone posted that Hornady load info in your other thread. I would not waste my money on a referance source that has that little effort put into it.

I have their Lott dies, brass, and bullets. But I will not have their reloading manual, until they do it right.

FWIW, 4320 holds the record as THE wildest swinging powder that I have ever done pressure work with; and that is a LOT of powders. Opening a new can of 4320 is like opening one of Forrest Gumps' box of chocolates. Ain't no telling what you are going to get.

Finishing the thought, I'm not surprised at the different velocities and different powder charges mentioned.

GAHunter,

I've got a couple of questions.

What is your aol on your Lott reloads?

Do you weigh each powder charge?

Have you double checked your scales for accuracy?
