Sweet. So 500 cases will last me at least three barrels. Haha.

Just wanted to confirm that the case length of the 338 NM is 2.492" and trim length is 2.482"?

I think that would be fine. I think my pilot for my trim tool trims them to around 2.485 or so.

Anybody shooting the 240 super bulldozers? What powders are guys using? I don't have the bullet listed in quickload.
Went and shot the 285 ELDm with N570 yesterday. Just a pressure test, but 94, 94.5 and 95 had 3/4" of vertical at 300 and were within 4fps. Didn't hit pressure in Peterson brass up to 97gr. I'm trying something different after reading this:

I normally do a pressure test at +.5gr but never really tried to gather data besides velocity and determine if a load is safe. I'm going to load 94.5 and do seating depth next. I anticipate doing powder fine tuning afterwards.

Long Range Load Development for F-Class « Daily Bulletin
This article was written in 2014 for the Sierra Bullets Blog. It describes one method of load development that is commonly used. There are other methods that can work also. Some guys first isolate seating depth and then fine-tune velocity with charge weights.

I can't technology. see next post.Anybody shooting the 240 super bulldozers? What powders are guys using? I don't have the bullet listed in quickload.

If you go back a little in the thread, I believe one member was running the 270's with vv-250Anybody shooting the 240 super bulldozers? What powders are guys using? I don't have the bullet listed in quickload.

It was near end season and I had few left over older 10+ sized brass and some 240 super dozers.So I dropped a few in to shoot a varmit or rock, or timber closer shot. Well I came off a timber ridge and run into a 6x6 and tested it on him,200 yrds all,would seen him crash except one big fir tree in path,15 yrds from where I shot him out opposite shoulder.Was broken up good but not as blood shot as i would of thought.Spring comes hoping supplies hit shelfs,want to work with it some more,1-10 T on mine

Regarding the trim length. I got these specs from Norma about 5 years ago. 2.492 min. 2.502 max.

I'm going to switch from the 270 Super Bulldozer and N-570 to the 250 Super Bulldozer II and I have N-565, N-570, Retumbo, IMR7828, a little RL26, and a little H1000 to choose from. Im6thinking N-565......The 250 SBDII has a better bc than the 270 SBD does, will obviously be going faster, which only helps stability and more speed is never a bad thing for a mono.
Knowing these bullets, I will probably just use my load data from the 265 ABLR's and the 250 SBDII, as my data for the 270 SBD closely matched data for the 300 Bergers as far as max charges. Just unsure where to start with the N565, has anyone used it for 250-265 grain bullets? If not I'll update when I get them.
