The 338 had been done but went back for a brake.

Before reassembly I installed a Pressure Trace II strain gauge.

I have Thursday and Friday to test loads because I leave for cow Elk Saturday early and I want to take this rifle if I can get it to shoot.

What are the specs on the 338/26 Nosler?
Estimated velocity with 225gr, 250gr Speer GS/Nosler Partition?
Overall case length? (I've got a Tikka T3 in 338WM that may be a candidate)
I'm really enjoying your build thread, thanks for bringing us along!

Since the QuickLoad estimate came close to actual the 185 TTSX I have confidence that the estimates for the others should be reasonable.

With a 24" barrel which is what I think your Tikka has:

225 Jacketed 3.4" COAL, @58,000psi: ~3,000fps
250 Jacketed 3.4" COAL, @58,000psi: ~2,850fps

The COAL might have to be shorter as this reamer is very short throated. I was hoping to try the CEB 252 but it will not fit until I throat it.

That is pretty cool. I'll see how things shape up for you and this round, but am very tempted to get my feet wet at this point.
Thanks for the response and continuous information flow.

I'll have to tag in as well, i'm interested to see how she does. Hopefully you can get some CEB's thru there! :D

I have to go with the 185 TTSX because it's the closest in load development, in stock in my loading bench and I really want to use this rifle for the cow Elk.

I have in reserve a 300 RUM that shoots Remington Premium 165 lead free which I think are Hornady GMX. They sure look like it. I used the GMX BC to range it. They took a pig at 500 with me missing windage by 1" and skipping it off a rib into the pigs ear. If I can get the final load for 200LRX I'd prefer to use those. 338 First.

Also, the 300Wby pushing 175LRX and a 300WSM with Federal Premiums Lead Free that will do the job.

If you are interested in a particular bullet in the 33 Nosler, let me know. I will work it up, shoot it, chron it and Pressure Trace II check it.

If I have the bullets, I will just do it.

If I don't have the bullet, you could send me 10 for the test. Since it's just a safety ladder and pressure test I don't need much more than that. I'll pay the postage. If you don't have them and I can get them from Bullet Samples for Sale-Sportsman Rifle Bullets I will.

Bullets that require longer COAL will be at the end of the list because I will have to throat it out a bit.

Not guaranteeing that I will do them all but I need justification to use up the factory barrel so I can put a 26 or 28" on it. Hehehehe:D

Got any pics of a loaded cartridge? Maybe next to a 338WM or -06 for comparison sake and to encourage my monster within to go ahead on this idea...

I forgot to throw the 30-06 into the picture.

It's not a real 338WM it's a necked up 270Wby run through the 338WM die It was my test case to make sure the seating die didn't change.
