Hey guys. I'm new here but I need some help. I have a .338 win mag in a Remington 700 Sendero which as many of you probably know is their top of the line over the counter rifle. Anything more is custom shop. It has an H-S Precision pillar bedded stock on it and a 26" fluted heavy "magnum" contour barrel on it. I want to e able to effectively and accurately shoot at LEAST 1,000 yards with it and be able to kill whitetail. I have a Millett LRS-1 6-25X56mm scope on it with 120 moa of adjustment vertical and horizontal with a one piece Millett 20moa scope base. I'm thinking about going with the new 45moa badger rail to compensate for my lower velocities ad harder fall. I was going to shoot the new Berger 250 OTM's but brownell's and midway are both on backorder till "sometime in August" was all the customer service rep could tell me. So instead I ordered the bore tech 245 grain solid V3 match bullets made entirely of a brass copper alloy! They are CNC machined on a lathe not extruded and jacketed as conventional bullets. The problem is I can't find any load data for a 245 grain so I called the company and they had data for a .338 Lapua but not a win mag so they told me to use the same load I would for the 250 grain berger's but to START AT THE MAX AND GO UP FROM THERE as their bullets are solids and have bands on the back to seal the bore and generate less pressure!!!! This alarmed me as conventional reloading wisdom and data always says to NEVER start at the max nor ever exceed it so I asked them again to be sure and they said yes start at the max and go up as you normally would watching for signs of pressure spikes i.e. blowed out primers ripples in the case neck and to start off seating .050" off the lands and go farther OFF the lands not closer that they have found ideal seating depth to be between .030" and .050" off the lands. That their bullets do better with a jump to the lands and that they also MUST be coming out of the barrel at LEAST 3,000fps to even stabilize which is my thin line of margin with my 26" 1-10" twist barrel!!! I have got to burn it hot to get that magical 3,000 mark. They told me their bullets are not designed to be shot or zeroed at 100 yards that they won't group that well that close because they haven't had enough time to "equalize' yet. That all of their personal guns are zeroed at three hundred and that their bullets are designed to be shot to the MOST EXTREME ranges possible! They are using the same bullet design as Cheyanne Tactical (i.e. CheyTac) in their .408 CheyTac cartridge that is designed to be shot at up to 2,200 meters!!!! Thanks guys for taking the time to read my long post and as always thank a vet, keep it safe, and send em down range!
