Got a late model 6.5Swede spotted at a good price, and wondered what the pro's & con's were on a conversion to something faster in a 22" barrel?

Looks like you could turn it into either of those or just AI the 6.5X55.

Case overflow H2O volume / usable volume with 140gr Berger VLD Hunting seated to SAAMI max overall length
6.5X55 57 grains / 51.6
6.5X55AI 62 grains / 56.6
6.5-284 66 grains / 61.6
6.5-06 68 grains / 60.7

With the last 2 a longer barrel would really be needed to see much real world difference IMO. The AI should yield about a 3+% gain in velocity over the standard. In my 6.5-284 I cannot seat bullets quite that long for mag length usage and have right at 59gr usable space. I can get that VLD to a little over 2900fps from a 24 inch barrel.

How long is the magazine system on the 6.5x55? Max COAL is about 3.150", where the 6.5-06 is at 3.340" and generally with a longer mag than that.

If the x55 is a modern rifle, you can easily push it 260 Rem and 6.5 CM speeds, and probably past them.

I've thought about doing that with my CZ 550 American 6.5x55. The reason I haven't is because to me the gain in velocity isn't worth it. It also won't get me where I want to be, which is to push a 140 grain Berger Hunting VLD to 3100 FPS. For that reason I've abandoned the quest for a 6.5x06. I'm saving now to get a 26 Nosler or 6.5 SAUM.

Thx for the responses. Dunno what the mag box max length is yet, and still tracking down the possible inexpensive acquisition. Ya'll seem to verify I'm grasping at straws or at lest pickin' fly poop outta the pepper again. AI'ing the Swede however might be the cheaper easyiest path to getting into or at the CM/260 MV's. The 22" barrel at this point would look like the next step and lots more spendy that I want to get into at this point, but it'll be dang tough to get 140gr'ers into 264WMg MV's from this platform...hence the appeal of the 26 Nozzler. cheers

My first thought was to get a new M70 in .264 WinMag because I get dealer pricing on them. The issue is they come with a 1:9 twist so that option is out.

Gotta ask. Why the need to get to 3100 fps with a 140 gr bullet? If you can only get to 3000 or almost there, won't turret twiddling correct for distance? The long range guys keep saying that it does (I'm just stirring up some trouble).

Geez...the 6.5X55 Swede is such an awesome cartridge! At least for what it was designed for. It will flat out shoot and deliver amazing knock down power on WT deer! I went to the range yesterday...took my future SIL to shoot a little. I fired two rounds with my CZ 6.5X55 Swede, pic below, and figured I was good to go. It was pretty hot and had others to practice with.



Oh, it's shooting a 1/4" low so I do need to adjust the scope a tad.

What's wrong with a 1:9??

Because 1:9 won't stabilize a Berger 140 grain Hunting VLD.

I guess it depends on the rifle. My 6.5 Swede with a 1:9 twist will not stabilize them. I'd rather be safe than sorry.

I think I'd buy me a Tikka and use the action and do a build off the action. That's what I've done and it's turned out awesome! Chad and Jason recommended it and I've never regretted taking their advice. Below is a pic of the rifle and below that is a target from two days ago. I only fired three rounds but they were pretty good.

Nice looking rig...but your pencil holes in the target are a little irregular LOLOL If I were to do that I'd have powder burns on the target I'm sure. up
