[QUOTE="James Jones, post: 170254, member: 8843"] The 243 Ackley will give you a bit more velocity especialy with the heavier bullets , the down side is the bigger case capacity will decrease barrel life a little and the Ackley case takes fireforming to get the full effect of the case desgine. I have never worked with the new 6.5-47 lapua case but it is rapidly gaining popularity in the long range comps so thats gotta say somthing about the desgine. Both cases will allow you to use the great lapua brass and both cases have enough power to get you to 1000yds with the bullets you have chosen. if you looking to get the flattest bullet path with the most on target "pop" for shooting varmints then you could also look at the 6mm-284 but your barrel life is going to be alot shorter. if your looking for maximum barrel life then you could look at the 6mmBR , I know it doesen't look that impressive but it does have a proven track record in the 1000yd comps. In reality you only looking at a few hundred feet per second from the fastest to the slowest of the 6mm's , the faster rounds will allow you a little flexibility in range and wind misscalculation and alittle more on target energy for shooting live targets at long range but the trade off is less barrel life and alot of the time the hotter rounds are a little more finiky with their load choice [/QUOTE]
