How has reloading for the 300 WSM been a pain? All WSMs are super easy to load. Watch that video I posted earlier and tell me that is hard.
Supply choices are Endless. Call Kevin at Black Hills. Last I checked they had over 1200(250 Count) bags of Winchester 325 WSM. Grafs is in full stock except for Nosler which we do not touch anyway. We can CNC perfect head stamped brass cheaper than Nosler 325. Bertram I am sure has a couple thousand. That is just the preferred one step die loading brass. We can 2 step 300 WSM in a machine. Or any of clients can with Redding dies. Bet we could find a couple semi's full of that. LOL.
David Emerson, we did once consider the RCM case. So close to running with that until I found an old 458 WSM reamer drawing. We made some tweaks and said let's do all the WSM. Love the RCM case just slightly lower powder capacity. In our notes I can see 2660 FPS with a Nosler Partition staying 5k psi below max pressure and loaded to the max COAL. We have never tested it specifically but can see your 2700. A 225 Accubond going 5k under max pressure should yield close to 2800 FPS with RL17 and your 25" barrel.
Hornady Brass, we have had nothing but problems with it.
Our Ammo is chrono'd using LabRadar and Magneto Speed. 1-4 FPS difference at times. Keep in mind we never go more than 5k psi below max. 60,000 PSI. Keeps our insurance rates manageablePowders won't be used unless 98% or more is burned.
We use stock box mags and a few different followers or AccurateMag DBMs. Always feed great on bolt guns. Semi Auto, Larue, Knights, and ACS Mags.
If we load for the TXH-F10 we set the machines(Not compressed loads) for a COAL of 2.840 and 2.900 for bolt guns" That is best for magazine feeding. 225gr Accubond or Maker TREX
2.840" - RL17
18" - 2625 FPS
20" - 2685 FPS
2.900" - RL17
18" - 2660 FPS
20" - 2710 FPS
Our favorite load is the 230gr ELDX. COAL 2.915. Bolt Gun only. Custom which we have a tech or even myself do a compressed load
18" - 2650 FPS
20" - 2725 FPS
24" - 2830 FPS
250gr WoodLeigh Power Points or Nosler Partition, Bolt Gun, 20" Barrel, 2600 FPS
Now looking at the 338 SS. On their website, they say can push a 250gr Berger EOL at 2800 FPS. No mention of barrel length. <EDIT, they use a 26". Their COAL is super long. 2.970! Even if we went to 2.930, my basic calculations with the same powder charge yields shows us being 100 FPS shy. All of their COAL are super long. It could be all true and the 338 SS can slightly outperform our WSM.
Both the SS and our WSM could technically be talking out of the other sides of our mouths. By most books, a short action shouldn't be more than 2.9 COAL.
We focus and build short barreled guns all the time to accommodate a suppressor. Overall lengths are 42-45". Same as a 24" common barreled rifle.
I obviously think our stuff is awesome but respect the insanely hard work of Sherman. We are smaller and newer. We work very hard to be the best. I am sure their are more campers in the Sherman tent. Am I going to try and sway them to sell their's and buy ours. Never. For those looking for something new, do your reading, make the choice that you think is best.
The only Bertram brass I have used is the 375 rum but I was happy with it.
Yes sir I had it in 28 nolser good brass
Thanks for your reply and the picture. The head separation is caused by over sizing . Setting the shoulder back too much when you resize. But it usually takes several times. When working with brass that has been shot and loaded several times I take a paper clip and make a short 90 degree hook on the end. run it down inside and you can feel the ring where it is stretching. When I feel that it is garbage time. Akso the whelen doesn,t have much shoulder so it would be susceptible to this.
I saw that too. Ejector flow
But primers can give false indications. If too much headspace they will be very flat. Another thing I use to gauge pressure is if the firing pin indent is shallow. Pressure is high so it pushes the firing pin back.
