[QUOTE="Fiftydriver, post: 12180, member: 10"] Sam, I have been using a 30" Lilja 1-8" barreled 6mm-284 for several seasons now for my extreme range chuck rifle and have learned alot of things about the 6mm bullets at extreme range. I started load developement with the 105 gr A-Max bullet but quickly found that at 3250 fps the accuracy fell off. I suspect the 3 groove rifling has something to do with this as I have spoken with many that are using this bullet at much higher velocites with great results. From there I tried the Berger 105's and found the same thing. I then tried the Sierra 107 gr Mk and accuracy held very tight up to 3600 fps which was a very hot load so I toned her down to 3525 fps. Accuracy at 500 yards is 1/5 moa is I do my part and at 1000 yards, if I read the wind correctly and get an accurate range measurement, teh bullet seldom lands outside a 10" circle. Still on game at 800 yards and out, the match bullet does not perform very well. I have made several center of body hits on chucks only to loose them to their dens. With a head or chest impact, they are dead instantly but the big match bullet just does not expand at all on chuck size game. THey actually perform much better on yotes and pronghorn at extreme range then chucks. Your bullet will open up better but you will have the issuse of velocity drop off and wind drift to deal with, especially at ranges past the 1/2 mile marker. I would agree with the earlier poster that the 87 gr V-Max may be a better long range bullet for your needs as it has a very good B.C. for a conventional varmint bullet at .4. Other options would be the new 90 gr Ballistic Tip and the older 95 gr version of the ballistic or Ballsitic Silvertip. These are spendier then the V-Max but I have always been impressed with these bullets. I developed a load in my 6mm-284 with the 95 gr Ballistic Silvertip loaded to 3700 fps but wind drift still did not compare to the 107 gr Mk so I stuck with the match bullet. You will fine it is difficult to score a kill at extreme range with a 6mm round without a solid chest or head impact. They just do not have the energy and bullet frontal area to instantly dispatch a chuck at extreme range. I have actually found the 25-06 loaded with the 100 gr Ballistic Tip to be a much bette chuck bullet/round combo at 800 yards then any 6mm bullet. Simply because the bullets are larger in diameter and will expand reliably. They can not compare in bullet drop or wind drift but in terminal performance they are better with a center of body impact. I just built my personal 2000 yard rifle chambered in the 338 Kahn(338-378 Wby with a 35 degree conventional shoulder). I chose this for several reasons, extreme ranging ability with 300 gr VLD and ULD bullets as well as custom 350 gr ULD designs. Plenty of bullet weight and energy to spot impacts at 2000 yards and plenty of frontal area to instantly dispatch chucks out to that range with any solid hit. In all honesty, as far as on game performance, the 6mm's, any 6mm, is light at 1000 yards. The best bullets to get to that range efficently are poor on game performers and the best 6mm game bullets are not efficent enough for 1000 yard varminting. ITs a tricky matter. To solve the problem, all you have to do is make head shots at what ever range you take a shot at [img]images/icons/grin.gif[/img] !!! That is never a problem for us!! Good Shooting, try a bit heavier bullet and see what happens! Good Shooting!! Kirby Allen(50) [/QUOTE]
