[QUOTE="goodgrouper, post: 199352, member: 2852"] Wow, not to be rude but perhaps this is one of those time where if you really don't know, you should probably not try to help! If you put 53 grains of 4350 behind a 75 grain bullet in a .22-284, you would be wearing your bolt as piece of jewelry. And the 75 grain bullet will never ever even come close to going 4000 fps in any length barrel. And the 75 grain amax will handle 3300 fps just fine. THe other bullets listed WILL NOT give red mist. THey poke holes and thats about it. OK, here's some load data from the 22-284 that I owned many years ago. 30" shilen select match 6 groove barrel: 6.5-284 norma brass necked down 75 grain amax jammed .005" into the riflings 50-53 grains of RL25 = from 3350 to 3500 with fed 210 primers 54 grains of N170=3300 fps 60 grain partitions w/ 55 grains of h4831= 3750 fps I used this gun for about 2 years and fired about 750 rounds through it before it started blowing up amax bullets due to very rough throat. Then I switched over to 80 grain Sierra smk's and they shot well but just poked holes in every rockchuck I shot with them. Some chucks even walked away with a perfect center hit. The smk's shot well for about another 200 rounds and then it started blowing them up too. I had the barrel borescoped and the first three inches of the barrel were abslolutely scary looking. I cut those three inches off, rechambered to a 22-250 AI and the barrel went another 600 rounds before I had to fire a Tubbs kit through it. Then it shot fine and I still have it to this day. I am approaching 2500 rounds total through the barrel. But the 22-284 was fun. I dusted quite a few chucks and prairie dogs over 1000 yards with it. Even cranked one at 1190 once. In my opinion, the 22-250 AI is a far superior cartridge to the 22-284. It gets within 150 fps and with a 3" shorter barrel while using 12 grains less powder. I will never have another 22-284 and probably will never have a 284 based case that is necked down any further than .264". It is simply too big of a case for small calibers to get any real gain in return. If you only want 700 yard performance, I would even go a step further and just shoot a 6x47 lapua or a 6-250 AI with 87 grain vmax bullet. They would be very flat to 700 yards and they would blow things up well. Or put an 8" twist in it and shoot 95 grain VLD's to double that distance very easily. [/QUOTE]
