[QUOTE="Fiftydriver, post: 35905, member: 10"] Jaeger476, Your load seems a little hot to me. This is a result of using a bit to fast a burning powder for this round bullet combo. You can certainly use 4350 with such a load but there is much more likelyhood that you will get into pressure problems then with powders such as IMR-4831, H-4831 or Rl-22. Of the three I would choose H-4831 as it is better suited for wide temp changes without large velocity variations. If your primers are feeling a bit loose after four firings, I feel you are puching this load about 100 fps to fast with the 4350 powder. More then likely you could reach the same velocities you are getting now with a slightly heavier charge of the slower burning powders and do so with less pressure and usually better velocity spreads. I look to get at least 6 firings per case with a belted magnum. If accuracy is great I will live with 5 firings but geneally I like at least 6. One thing to remember using a VLD style bullet, velocity does not mean squat in teh whole skeem of things. At extreme range the difference of 100 fps at the muzzle is basically meaningless out past 300 yards and generally it will add roughly three firings per case to your brass life. My recommendation, try a bit slower powder and see what happpens with your case life. As far as accuracy goes, if you can not find a load the rifle likes quickly, I agree with LB in that I would not burn the barrel out trying to find that magic load. It should not be that hard to find a good load quickly the way your rifle shot before the work. If you can not find the accuracy you want get ahold of PGW and I am sure they will figure the problem out for you just as any quality shop would. Good Shooting!!! Kirby Allen(50) [/QUOTE]
