Put the 300 blk on a diet

It is an AAC 700 300 blk. They came with a varmint profile barrel. I felt this was to heavy so I turned down the barrel to .618 and re tapered the ends. I just turned it with the action on.

I don't know how much weight I saved but it's much lighter now and more nimble.
On the plus side the barrel is now free floated.
Don't mind the mess I was going to clean the gun room but this was more fun

Nice work, mine has a heavy barrel as well, it could have been a very nice woods rifle if not for that. Why we need that much steel for that little cartridge I have no clue...

I have the AAC also and find the rifle too light [and the stock too short] now, I had to really lighten the trigger pull or it would pull the sights off target.
as it is I'm looking for a heavier stock, and a way to add some weight to the muzzle now.
I can't even imagine it being lighter.


you did know that relieving the outside of the barrel will allow the inside to grow larger in response.
that's why barrels are tapered from back to front.

Here is my daughters, so far it has done great with my 144 gr mold and 13 gr of 2400. I need to get a set of quick detach mounts for the 10x scope.

I assume your talking about the 7 not the 700?

What the hell are you talking about
The best I can figure is your talking about the profile raising at the end? Have you seen an m4 barrel?
the reason I flare the end is for the supressor to have a good shoulder.

A Remington factory varmint barrel is straight through most of the length.
I'm not sure what you were trying to get at?

I have a Bushnell elite 3200, until I get the mounts I have a set of weavers that will work, how is your follower? Mine tips the nose up too high and keeps it from feeding.

Mine works perfect is the Internal mag seated fully and I stalled right side up?
Mine feeds 247 noe to 110's fine. I would check to see if the spring is fully seated on the follower as well. The rem 700 mag is one of the most bomb proof out there

Never took it apart, I will check that as I have never had any issues with em either. It is also leaving long gouge lines on my brass, but it shoots very very well and I can't complain about that.

The scratched brass is because the lips are sharp you can take some 1500 and smooth it up or just shoot it and it will fix it self over time. Most of my new 700's have this problem, I just keep shooting them and it goes away.

It has been shown that cutting the outside of a completed barrel does make small changes to the internal bore dimensions.
Just cutting a small small shoulder on the muzzle of a target rifle for a front sight mount can lead to a tiny belling of the muzzle.
For most shooting it will never be relevant but to target shooters it is an issue.

For most shooters it is one of those things that exists but will never really matter.

apparently I'm talking about your Remington not being an AAC.
AAC is advanced armament company [corp] and developed the 300 b.o. cartridge in conjunction with Remington.
their rifles however are not in anyway heavy weights.
they are in fact almost too light for what they are, and that I have been trying to add weight to my AAC rifle.

the turning of the barrel thing was mostly covered by Brad, just turning the outside of one down will change the internal dimensions of the barrel.
a good barrel maker will factor this into his internal dimensions then turn the barrel relieving the external stress and allow the internal dimensions to 'grow' to the appropriate dimensions.
there is some science involved with metal working.

I'm guessing the whisper also came after Remington stole it and developed it into the AAC blackout.
Ps the Remington barrels are hammer forged not cut.
I turn blanks all the time from many different manufactures as well as flute and octagon them. I hand lap my barrels and have not seen any difference before and after as far as the bore growing out of spec.

Oldaheart,
would you consider turning down a barrel, for a fellow member? And what would be the cost?
I have a stainless steel bull barrel for an AR 15, that I have had laying a round.
I think an octagon AR barrel would be very cool.
