QL Request 300 RUM and 300 WSM

wildbill141 · Jan 4, 2016

Would someone be so kind as to run a QL for each of the following?

300 RUM- 26" barrel
200 ELD-X (OAL 1.53, bearing surface 0.700)
Retumbo
COL 3.70
Note: 94 grns gave 3190 fps

300 WSM-24" barrel
200 ELD-X
IMR 4350 and H4350
SAaMi OAL

Thanks

I would not load from this or think that the PSI is at all accurate. I do not have a lot of confidence in QL's estimates of the 300 RUM and retumbo powder. I think QL's Pro- or Degressivity factor is not very accurate for this much retumbo. I could be wrong on which component of QL is off, but QL is just a supplement to published data anyways.

Not knowing your case H2o capacity, this could be, and probably is very wrong with the exception of the grain charge weight and velocity.

I had to use the 208 gr AMAX with modified bullet length since QL doesnt have the 200gr ELD yet. Changes more things...

Code:

Cartridge          : .300 Rem Ultra Mag
Bullet             : .308, 208, Hornady A-MAX 30712
Useable Case Capaci: 100.073 grain H2O = 6.498 cm³
Cartridge O.A.L. L6: 3.700 inch = 93.98 mm
Barrel Length      : 26.0 inch = 660.4 mm
Powder             : Hodgdon Retumbo ?

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.

Fwiw... out of curiosity I used my bullet comparator to double check the bearing area of the 200 Hornady versus the Nosler 200 AccuBond. They are virtually identical except the hornady has just a slight couple thousands less. I personally have no problem using data found for the 200 aB for the Hornady bullet....ymmv though!
If you do a Google search using "Hornady load data" as a phrase you'll get to their eldx data..... from what I've seen their data is pretty strong so I don't think the hornady is going to be a sticky bullet at all.

Thank you for the response

No luck in the 300 WSM with the 200 ELD-X. Tried IMR4350, H4350, H4831, RL23.
Very good accuracy in 300 RUM with 93.8 grains Retumbo, Nosler Brass and Fed 215 (3155 fps).

Nothing came out decent with the WSM.. Is it a seating deal or twist problem?
