Thanks all for your advice and experience. I ordered the Bushmaster 24"Varminter upper assembly. The barel is fluted which will shave a small amount of weight off. I have read some articles of folks having great success with it and 55 gr. VMax. I,m going to give it a try. I do hear what you are all saying about the weight. I'm sure it will be a blast to shoot!
As far as having to lug it around. well that I am about to find out. Going to add on a Harris bipod. I just hope it won't be like lugging around an anvil!
