6.5 x 06 Just input

[L.Sherm]

Nope 30-06, .270, and 6.5-06 is all the same 30 degrees

I know I run a 6.5x06AI

Yeah I have seen a lot of people mention that what's the advantage?

30-06, .270, and 6.5-06 is all the same 30 degrees

Yes, they are all the same. 17deg.

308 win is 20deg, for example

6.5 creed is 30deg,

Ackley Improved is 40deg.

The 40deg shoulder enlarges the case somewhat, allowing a few more grains of capacity. Also, the steep shoulder angle limits the brass stretch, and hence the amount a guy has to trim

Yes sorry 17 degree. So besides maybe a little more velocity and not having to trim as much there isn't many benefits to the 6.5/06 vs 6.5/06 AI? I also have plenty of .270 win and 30/06 brass I can convert to 6.5-06 The only reason I'm thinking of running either is because I have a .270 win I never use and have plenty of 6.5 and 6mm bullets that I already use for reloading so figured I could get rid of the .270 stuff and switch to something I already use for a different caliber. And I was trying to find something where I wouldn't have to do any machine work to the bolt face. Since both run a .473 cartridge base.

Some cartridges benefit AI more than others a 280AI is worth about 200fps over a 280 Rem.
I'm getting 3150 out of a 6.5x06AI in a 26" tube with a 140, never been around a straight 6.5x06.
I do know the more AI I get the better I like them

The primary advantage of moving the shoulder forward and changing the shoulder angle is increased case capacity. I have a .30 Gibbs ...

 

[Hand Skills]

Not to sidetrack, but @FEENIX is the 30-06 'medium neck' a 280 RCBS improved (30°) necked up to 30cal? I havent encountered that wildcat before! Very interesting!

My 6.5-280AI runs 2997 with 58.5 gr RL26 and 140 ballistic tips. I just use remington 280 brass and do full case prep including a skim turn and weight sort. My favorite group is 3 shots inside a 3" targdot at 620 yards lasered. 25" barrel. This rig has precision and accuracy.

I do not know for sure, but you are correct that the RCBS version has a 30° shoulder angle, but I also know that Mashburn prefers the 30°.

Hello I just made some dummy rounds for fun to see if the 30-06 die would work with a 6.5 mm bushing. I started with 270 win brass resized with a 270 win die. And then used the 30-06 hornady match grade die with a .281 bushing then I opened it back up with a 6.5mm mandrel. I mean the 6.5 bullet works the only issue I had was when I sized it down with the 30-06 die it kinda deformed the shoulder a little. Is this normal for sizing down brass for the first time? Instead of a nice sharp angle it is kinda rounded if that makes sense. Will fire forming the brass fix this?

 

[L.Sherm]

Sounds like your trying to pushing the shoulder back, screw the die out a little all you wanna be doing to start is neck them down

Copy thanks do you think they would still be safe to shoot? As long as they chamber. I don't even have a barrel for the rifle yet so this is all just a dream at this point haha.

 

[L.Sherm]

Yeah they should be fine to shoot.

 

[a_savage02]

What's the best twist and barrel length for the 6.5-06?
