Hey, can anyone run some number for me quick for the two cartridges listed below. I’d love to know predicted velocity and pressure. They both shoot great and fit within safe ranges, would just like to know the numbers.

1. 6.5-06
105 grain CBB MKZ (all copper, like a Barnes TSX)
54 grains of RL17
Remington 25-06 fire formed cases
Win Large Rifle primers
24” Shilen Barrel.

2. 35 Remington
200 Grain Hdy RN
36.5 grains of H4895
Remington brass
Win large rifle primers
20” Marlin barrel

Thanks so much guys!

For better numbers, an AOL is needed (if QL has your bullet).

Even better, figure out the seating depth.

And I am not sure how well it works with solids.

CAUTION: The following post (or a page linked to) includes or discusses loading data not covered by currently published sources of tested  data for this cartridge (QuickLOAD or Gordon's Reloading Tool data is not professionally tested). USE AT YOUR OWN RISK. Neither the writer, The Firing Line, nor the staff of TFL assumes any liability for any damage or injury resulting from the use of this information.

Just to show you what I mean, I ran two random AOLs on the 35 Rem load.

Code: 
Cartridge          : .35 Rem.
Bullet             : .358, 200, Hornady SPRN 3515
Useable Case Capaci: 41.925 grain H2O = 2.722 cm³
Cartridge O.A.L. L6: 2.450 inch = 62.23 mm
Barrel Length      : 20.0 inch = 508.0 mm
Powder             : Hodgdon H4895

Fill. Charge   Vel.  Energy   Pmax   Pmuz  Prop.Burnt B_Time

94    36.50   2008    1791   29501   5140     81.2    1.321

Code: 
Cartridge          : .35 Rem.
Bullet             : .358, 200, Hornady SPRN 3515
Useable Case Capaci: 36.862 grain H2O = 2.393 cm³
Cartridge O.A.L. L6: 2.250 inch = 57.15 mm
Barrel Length      : 20.0 inch = 508.0 mm
Powder             : Hodgdon H4895

The Quickload results for the 35 Rem load are:

Code: 
Cartridge          : .35 Rem.
Bullet             : .358, 200, Hornady SPRN 3515
Useable Case Capaci: 43.313 grain H2O = 2.812 cm³
Cartridge O.A.L. L6: 2.505 inch = 63.63 mm
Barrel Length      : 20.0 inch = 508.0 mm
Powder             : Hodgdon H4895


Step    Fill. Charge   Vel.  Energy   Pmax   Pmuz  Prop.Burnt B_Time
 %       %    Grains   fps   ft.lbs    psi    psi      %        ms
+00.0   91    36.50   1981    1744   27895   5148     80.5    1.350

I went an looked up some details for the other load.

There are several problems. The best chance for a reasonable prediction really needs an accurate % fill. Since this is a wildcat, the "default case capacity" in Quickload is iffy at best. Then you picked a solid copper bullet with a weird hollow base.

If you will take one of your cases, your powder and your bullet you may be able to get a reasonable estimate of the amount of powder needed for 100% fill at your AOL (including up into hollow base). Divide your actual charge by the 100% charge and you will get percent fill. With a decent percent fill, we can plug in a load that might be close.

However, the software was not really set up for solid copper bullets, so there will still be more uncertainty than normal.

Now get a good estimate percent fill and give us a measured velocity and we would have a lot more to work with. I could probably tweak out a decent estimate of pressure (by fudging the factor for bullet resistance).

P,

Thanks for the well thought-out response. Sounds fun to try and figure all that capacity stuff out empirically... but with hunting season upon us, I'm not sure when I'll get to it.

Thanks again.
