[QUOTE="AZShooter, post: 865019, member: 5219"] I have had several 284 win chambered rifles and often marveled at what the 6mm-284 would be like. A bit over 3 years ago I had Pacific tool and gauge make me a reamer and since then have made three 6mm-284s. The one that would most interest you is a 28" #11 profile 5R Bartlein with 1 in 7.5 twist put together to shoot the 115 DTACs. It didn't shoot them accurately enough for me. I experimented quite a bit wearing out the barrel in the process. Ended up with the 107 Sierra then the 105 Berger target hybrid showed up and I switched. Really like that bullet. Now approaching the 1000 round mark. My borescope shows a horror show of heat cracking way up the bore. Clean up is getting slower but that rifle still shoots very very accurately. I have another Bartlein 5R 1 in 8 twist sitting on the shelf when this one finally wears out and begins to loose its accuracy. The other two are sporters with Rem 243 takeoffs rechambered to 6mm-284. The heat cracking shows up early but they still shoot well. They are Remington barrels so they are not as easy to clean as the bartlein was with same round count. The beauty of these barrels is they don't cost much and offer amazing performance. The first barrel I ever chambered myself was one of those 243s. It is a 20" barrel I got for $40. To my amazement it shoots the 87 gr hornady V-max at 3375 fps. The other sporter is a 24" barrel and it shoots the 55 gr nos bt at 4175 fps. I'd shoot the 105 bergers but Remington barrels don't have enough twist. Enjoy the build and the very best LR performance from a 6mm. FYI I use 6.5-284 Lapua brass and think it is the best brass for the 6mm-284. I used the reamer to make a simple forming die with a section of an old 264 win barrel. Helps get the necks closer to 6mm with no stress or damage. This forming die really helps if you want to neck down 284 win brass.
