Thanks for the information. What powders, primers and cases are you using?jhalcott said:IF (big if) all you shoot at is paper, there are lots of bullets to use.If you plan on an occasional deer /big game hunt you might have to soften the bullets and slow them down some.You don't say WHAT case you will be using,only that you want 308 speeds.From a 30-06 you can get 2400 fps with a 311284 (210 grain) and 311644 (190 grain).These are with MAX loads. In the 308 ,311332(180 grain) gets 2300 fps and the 311644 (190 grain) gets 2400 fps,again MAX loads. Lyman 47th edition of reloading handbook. I have the 311334(187 grain) that I am playing with now. It is a pointed bullet and the 3rd edition Lyman book says 2500 fps is possible. I haven't been able to get that fast with accuracy YET.Another 30 heavy I'm trying is the Lee 200 grain. I'm using this at reduced velocity for culling deer around a golf course. It still makes noise but is DEFINETLY quieter than factory ammo. The game wardens will NOT allow the use of a silencer. This bullet is cast of pure lead and loaded to about 1000/1100 fps. Most shots have been within 50 yards and very successful.
I use a lot of R7 and have used the other powders. Your right I don't need 3000+ to do the job. However I do need to place the bullet properly so accuracy is the first order of business. Thank you for the information.jhalcott said:Lee ,most of my cases are Winchester. 90% of my primers are cci ,and I use what ever powder work best in MY guns. Your mileage may differ!
RX7,imr 3031,h335 and H4895 will get you above 2300 fps in a 308 shooting the 311334.Just get a loading manual for cast bullets and READ IT. Start low and work up. I HAVE ruined a barrel or two trying to get 3000+ fps from cast bullets.(don't try this at home). Come to think of it, I've dented a few chronographs too! One thing for sure, a bullet does NOT have to break the sound barrier to kill a deer ! As for the 30-338 case I am not sure,BUT the Lyman book shows 2775 fps for the 311334 and a charge of WW760.this was with a 300 WINCHESTER mag. THAT ought to ruin bugs bunny's day!
