JJ, I know why you want the fluting, and I completely support the plan for your build, but I'm not sure if you can even find a pencil barrel with fluting because of how thin it is already. but if you can, more power to you.

yeah, sorry guys, had it backwards. been a long time since I had to even deal with 7.62x51, so my brain was thinking it was the same as the 5.56 to .223. https://www.all4shooters.com/en/Shooting/technics/Winchester-308-762x51-Nato-calibers/?p=2 this link talks a lot about the pressures. http://www.303british.com/id36.html this link talks about case thickness, chamber dimensions, and a little of everything else. both good reads.

Welcome from Wisconsin! I have a few Canadian friends but they are all liberals (so not close friends. haha), glad to see someone up there that is conservative. :P

generally the thought is the military had slightly looser tolerances. so a rifle chambered in 5.56 could shoot .223 and a rifle chambered in 7.62 could shoot 308. but then you have the .223 wylde chambering that is specifically designed to shoot 5.56 or .223. I am not sure if there is a .308 chambering like similarly designed like the .223 wylde, but I think you should be able to shoot either out of your gun if they say you can. but might want to check your warranty if you have one. haha.

yeah I see the wolves more than coyotes where I am. seems to be plenty of deer though, so I don't think wolves area problem yet. although everyone still hates them. I think it's one of those things people grew up with and so will only die with time.

yup, 100% correct on the greater the mass the longer it takes to heat up, but the less the mass the quicker the barrel cools off. so just have to decide what type of shooter you are and how many rounds you will be putting down range in what type of time period. as for fluting: fluting doesn't make a barrel more rigid, but because fluting cuts weight, you can have a barrel that is more rigid with fluting than a thinner barrel that doesn't have fluting. also, fluting creates more surface area that is exposed to the air so it does increase cooling, but not by much as again mass is the big factor in cooling. so basically fluting is for a person that wants a more rigid barrel but at the same weight as a slightly thinner barrel... or someone that just thinks it looks cool. haha.

did anyone else get turned on?

yeah, I love the peace and quiet and privacy that comes with it. but everything good comes with a price. lol.

BHW used to make barrels for Rainier arms, not sure if they still do though. but yeah for the price, BHW is definitely worth the buy. I do like how you can purchase a bolt with the criterion barrels, and seems to have great customer service on the forum. :P Plus yeah, being from Wisconsin automatically puts it up with the best, right shepp?

I agree RRS, most everyone want something for nothing, and aren't willing to put in hard work for their own comfort and happiness.

criterion barrels are a great option also, seems to be a favorite around here, but I don't have experience with them. I am a fan of black hole barrels though.

it's not your fault Wal-Mart doesn't carry real ammo anymore.

JJ, and if you are worried about burning up a pencil barrel, don't. look at the m4s the military uses. they don't have thick barrels and an infantryman has no problem sending a few thousand rounds down range in a few hours. trust me, it may hurt accuracy after it warms up, but within 300 yards you have nothing to worry about. besides, if you have the money to shoot enough rounds to do damage to these barrels, you got enough money to buy a new one. and enough money for me to be your new best friend. :P

wont be long until those democrats try and label us with arm bands. but we wont let them mark us and group us in camps without a fight (that we will win). too soon on the reference?

hey guys, wasn't there a lightweight lower that had some cutouts in some locations such as the magwell to make things lighter? trying to think who made that, but it's not coming to me.

thanks for the updates shepp, hoping they get more m5e1 stuff in stock soon.

wash, why do you think we brave the cold in a small little shack? you hit it right on the head with the definition. ;) when it's that cold you got to take off the shanties of your women to create some warmth with friction.

my house is an ice house when I piss off the wife.... like when I am posting on this forum and I ignore her while she is talking... funny that's what is happening now. lol.

I have excede internet. was the best in the area. I am literally surrounded by thousands of acres of state land on 3 sides of me, so I'm about in the boonies as I can get. power just flickered off 10 min ago, and that is common out here. the bears and wolves run things out here, and apparently some cougars have been spotted recently.

I thought all the Obama democrats were banned from this forum. lol.

go 7075 aluminum, though most people wont notice the difference between 6061 and 7075, there is a big difference in strength if you talk to metallurgists. and if it is budget you are worried about that keeps you from carbon fiber, I suggest using some light weight furniture from magpul or similar products. definitely the way to go if you want a light weight rifle. and price is not bad at all.

I've been looking into getting a nice rest to zero my rifles, but haven't the foggiest of what I should get and from where. I usually just shoot from a bag or harris bipod.

something I would love to do man. cold doesn't bother me, heat does. boat? marinas? winter in Wisconsin we drive our trucks out on the lakes and ice fish. haha. you would be hard pressed to even find an area not frozen over, and even then, all the boat launches would be covered with ice.

planeflyer, yeah I had a .243 hornady load for deer enter in a deer one time and then hit the far shoulder blade and then bounce back and came out on the same side the entrance wound was and created a huge hole. was pulling fragments out of that side, good news was the other side was perfect. lol. mrmackc... last night was a fluke. not letting me quote again this morning. the things I try and quote just keep loading and loading, but never pop up. I have satellite internet since I am so far in the middle of nowhere and it sucks, in the middle of the night it is better because less people are using it.

I just want the Aero Prcision M5 builder's set to be in stock
