[QUOTE="Timber338, post: 722421, member: 33822"] First off, how confident are you that the gun is capable of sub 4" groups at 400 yards? Maybe I missed it but I don't see any info on the gun. Before you go and spend more money and time on ammo is there a chance the problem could be with the gun? Are you using good cleaning methods every 20 to 25 shots? Next, the big red flag that may or may not be causing you problems is the brass you are using. All of your components are high-end except your brass. you mention that you turned the case necks. How much variation are you seeing in the wall thickness? My experience with winchester is that the brass can be extremely inconsistent in just about every aspect. A good rule of thumb with brass is that any variation in the neck thickness will also be present in the body of the brass... so you can only get so far with turning necks. Considering how much money bullets/powder cost plus time and effort reloading and going to the range ... it's not worth trying to save money on brass. Buy good brass like lapua or norma or nosler. I have had excellent luck with Nosler brass, all of the brass is weight sorted to within 1 grain and neck wall thickness is within .001 on all of the brass.... at least with the batches that I have used. And I would personally do the shooting for load development at closer ranges so you are not magnifying any possible human error. I normally shoot at 100 and sometimes at 200. [/QUOTE]
