______________
Brand - Bartlien
Contour - straight taper, heavier weight ( seeking guidance on specifics)
Twist - 7 per inch
Length - 26 inches or 28
Material - stainless
Groove - 5R
Options - 1/4 radius spiral flute
- hand lapping

You could call Bartlein directly and tell them exactly what you want to do with the gun and they will help you specify the perfect barrel. They are awesome.

I'd suggest heavy varmint with 1.0" muzzle for the contour. Bartlein doesn't list it, but they make it often and will know exactly what you mean. This is a heavy contour but not too heavy. If it's just for shooting prone or from a bench at long distance then this is a great option.

I'd suggest 28" finished length. You don't have to worry about specifying the length to Bartlein. The blank should come at 29" and can be made to any length 28 or shorter by your gunsmith.

I'd suggest a 7.7 twist or 7.5 twist. In my experience going with more twist than necessary can hurt precision. That bullet works perfectly in a 7.7 twist so no reason to go faster.

I'd recommend 4 groove. It's easier for your smith to dial in and they shoot as good or better than 5R.

Don't worry about specifying hand lapping. All Bartleins are lapped and they know what they are doing.

I shoot 153 ATips in my 6.5 Creedmoor with a Bartlein 28”, M24 contour, 8 twist 5R barrel and it’s very accurate. Contour will come down to how much you want to carry. If just going from car to firing line then straight taper would be fine and some in PRS style matches use straight contour too so would come down to your physical strength. I have proof comp contour barrels and MTUs also.

As mentioned I wouldn’t go 7 twist. 7.5 would be fine.

Definitely go 28”. I have only run 28” barrels in my Creedmoors since 2008 as I like the free velocity and the length is no issue even in matches.

Stainless and 5R are good choices as that’s what my Bartlein barrels are. You do not need any hand lapping in Bartlein barrels. Don’t mess with how they come. I have never been a flute guy but I have one barrel with them. Personally I wouldn’t flute it but your rifle.
