I have been shooting my .340 for a long time. I haven't kept count, but I am sure I have sent well above 1000 rounds through it, perhaps nearly twice that, but during that time I have not really experimented much with different loads. Initially I bought this caliber for hunting elk, but truthfully all I really knew of the caliber was that it had massive power and great ballistics. I began loading 210 grain Nosler Partition bullets, and had good results. I didn't kill much game with it, but it worked very well in all "normal" hunting distances and conditions. Briefly I tried 150 grain Nosler Ballistic Tip bullets to see how fast I could make a bullet fly, but my accuracy was poor. As my experience and confidence grew I began shooting more distant targets and to be more accurate I began shooting 225 grain Nosler Accubond bullets. In a short time I found a load that was very accurate for me and for years I have not changed the recipe because it works. I have on good days shot MOA groups, and occassionally better, even at distances beyond 1200 yards. Given the opportunity to place my bullet accurately, there are few animals on the planet that cannot be taken with this amazing caliber.
This is my load. It is a MAXIMUM LOAD.
225 grain nosler accubond bullets
88 grains of reloader 22 powder
federal 215 magnum rifle primers
3035 ft per sec .550 BC
I actually get about 3015 fps with this load, but I have a 24 inch barrel.
