The only load I find for 8x58R in my books are in the "Wiederladen" from Dynamit Nobel 5�th ed. Using the RWS soft point 196gr (=12,7gram) OAL 77.0mm Using Rottweil�s powder R902 min31.0gr, max33.0gr=1837f/s R903 min33.0gr, max36.0gr=1887f/s R904 min37.0gr, max 39,5gr=1887f/s About the primer failing to ignite the powder I would check that the passage from primer to powder and see if it is not blocked. If not I should change primers / | |||

159 grain bullet...52.4 grains of IMR-3031 196 grain bullet...54.0 grains of IMR-4895 198 grain bullet...54.5 grains of IMR-4895 These are naturally maximum loads... | |||

This is from Lapua's Reloding manual 1993 Where thay have tried to group the powders after burnrate.It says in the manual "The relative burnig rates of some of the most common powder are presented in the following list. THE LIST GIVES ONLY AN INDICATIoN AND IT CAN NOT BE USED AS A GUIDE FOR RELOADING. In Certain calibers the mutual order of the powder may even change" And that was before I tried to type it with the possibilitie of adding errors, So beware of the list  19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 Good luck/ | |||

It would appear to me that we are confusing cartridges: There are a number of 8x58R cartridges and the 8x58 R in the DN manual is not the same as 8x58R Danish cartridge! I scanned my files and came up with the following sources of info for the 8x58 R Danish: Handloader #171, Cartridges of the World, Visier #10 October 1998 and a posting on Grey Beard Outdoors. By the way: What is the measured case capacity of the 8x58 R Danish? Guus Verheijen | ||

Guus, I checked to see how much IMR 4895 the 8X58R Danish would hold, still leaving room to seat the bullet. I came up with 60 grains. I think the data from Cartridges of the World, except for the original military loading, is way too hot for a rolling block action. The first shot I fired from this gun had a load of 52.5 grains of some unknown powder. I say unknown because I bought the ammo already loaded from AmmoDepot. The primer was flattened and the case stretched so bad it would not come within .035 of rechambering. I suspect AmmoDepot was loading per the data in COTW. I pulled all the bullets from the rest of that batch and dumped the powder. Now I'm working up slowly with IMR 4895. | ||

The data I posted is for the cartridge you specified. The 8x58R Danish. As for detonation, that may only occur in very large cases with very small powder charges. I say "may" because in over 50 years of shooting and 40 years of reloading I have never personally experienced this situation, nor have I ever met an honest reloader who has said that he has. | |||

Hi again I trust that Guus has the right data but for your curiosity I give you the data of the 8x58R cartridge in DN (in mm) Rim 12,7mm The brass used in the DN book are reformed from 9,3x72R So now you know what I almost tricked you with PerN | |||

Hi again! Maybe better luck this time with the 8x58R  I found this page on the net | |||
|
| <gunboat> |
PerN, Ah yes, there seem to be quite a few different cartridges that are 8 X 5Y where Y=any number between 2 and 8 inclusive! I looked at that page in Swedish. It looks like it has some useful info. I can't read Swedish, or Danish or even German, but I know some folks who will take a stab at it for me. Thanks for the lead. | ||

Don't worry 'bout the strength of the RB action, it'll hold! I have a 8x58R Action that has been rebarreled with a 50 BMG barrel and chambered for 500 Nitro Express. It'll eat the hottest loads for this calliber and stand the pace. Barrel came from a Spitfire that ended it's days in Sweden during WWII. Henrik | |||

Forgot to ask: Do you use military cases that use Berdan primers? They tend to clog up in the "werry" small channels leading from primer to powder. they were only meant to be fired once, not reloaded many times. Thorough cleaning or opening this channels slightly (to say 1,25-1,5 mm) will solve this problem once and for all. Henrik | |||

Henrik, You say you rebarreled your Swedish RB to 500 nitro express? I am amazed at the strength of that action which was basically made for black powder. Any idea what level of pressure it generates? I have now fired all my brass one time. It is commercial stuff made by resizing 45-70. I checked to make sure all the primer holes or channels are wide open. The plan is now to load up 43 grains of IMR4831 behind a 170 grain Speer and see how it groups. | ||
|

The saga continues... I just got back from the range. With 43 grains of IMR4831, about 10 granules of powder are unburned in the barrel after each shot. Velocity is low, the pressures were so low that the necks have not expanded. Seeing as I'm already leaving unburnt powder, I guess I'll have to go back to the faster burning IMR4895.

Gunboat, actually it's a mix breed! The action is from a model 1896 wich is the original for the 8x58R and therefore nitro proofed per se, and the barrel from a 50 BMG as i have told, so both are up for the job. I'm not trough develloping a perfect load for BP, after all it's a long distance gun and i'll use it at +500 meters for targets. Twist is 1/16" so i need a bullit of more than 6 cm in length, that's over 750 grains and so far i have not been able to find such a mold. The biggest i'we found and ordered is a 650 grain SAECO that's special order and i'll have to wait for them to make it first. Currently i pack 145 grains of Swiss #1� behind a 450 grain Lee bullit, that gives just under 1900 fps at the muzzle. Plan to use some nitro when time comes. Henrik | |||

PerN, You are right, it was a very mild load. I had been up to 40 gr of IMR 4895 but I was getting occasional misfires. I thought the misfires might be from the case being only a little over half full, so I went to a slower powder (IMR 4831) thinking I could fill up the case more. But that wasn't the right way to go so now I've loaded 43 gr of IMR 4895 and am using new primers. This the first reloading I've ever done and I'm going slow and careful so I don't overpressure anything. I'm just starting to get a glimpse of how case volume, bullet weight, and bullet diameter can affect the performance of a given weight of a certain powder. | ||
