Re: 338-375 Ruger Demon

I took my 338/375 down to the range today with just a few loads. I am using 200 grain GS Custom projectiles in front of 86 grains of ADI 2209. This was the last of 4 loads which produced an average of 3,318fps with no signs of pressure. I can't weight to try the next loads.

Re: 338-375 Ruger Demon

I think it would be a great wildcat. I'm currently getting a 300-375 Ruger done. Great case design, especially for wildcating - not to sure about brass quality though as Hornady is the only option.

Rigmaster10:

What length barrel are you using? Your reported velocities are very high.

I did an extensive search and only the 338/378 Weatherby in some loading manuals list 250 gr bullets moving faster than 3100 fps. I realize the load data is usually done with relatively short barrels but your results seem off the charts.

The 338/375 Ruger is very similar to the 330 Dakota. Dakota lists their 250 gr bullet at 2900 fps. Every loading manual I found lists Dakota loads generally running in the 2700-2800 fps range.

Sure a 30-32" barrel can add some velocity but 3120 fps????

Re: 338-375 Ruger Demon

Like stated earlier I just don't see it either, sure the 375ruger is a good design for a shorter cartridge with a decent capacity, but necked down to 30 or 338 it still comes up short of the 300 and 340 wbys they are at 101 and 101.8 h2o capacity, the design of yours depending on reamer design is 95-97grns h2o and both cases are rated 65k psi, a 340wby will do right at 3000fps with a 250 grain bullet and the double radious shoulder is superior to the rugers shoulder design and your getting 120fps more, are you using a 38" barrel with your compressed load of N570?
