6.5x55 swede in a Handi?
« on: June 23, 2008, 05:13:24 AM »
I looked several times but have not seen anything about it, but was the Handi Rifle ever offered in 6.5x55 and if not is there any way to have a barrel rebored to it?  It is a round I've had my eye on and thought the Handi would be a good way to try it out.

A Hornet or 223 barrel could be rechambered and rebored to  6.5x55, my choice was to have a custom barrel made, still waiting tho, was headed for a 260 Remington, but switched horses after more research.

   Tim what did you find in your research that caused you to "switch horses"   ???  Jim

A lot better performance from the 6.5x55 with heavier bullets, it can easily be handloaded to exceed the 260, compare Conley's 260 loads to their 6.5x55 loads. ;)

   I see what you mean Tim .  As always you are an excellent source of great information.  Since Meadhall broached the 6.5 subject, what are your feelings on the "super sexy"  6.5 x 284 ?  As you said a Handi barrel would have to be built for any 6.5 & I suspect a 6.5 x 284 could be "light loaded" just a bit to keep from burning the barrel out ?  :-\  Jim

I wasn't concerned with burning the barrel out, the .500" case head and subsequent breech thrust was my concern, been there, done that with the .300WSM barrel, don't care to go there again, that investment was minimal, I want this one to work.  ;)

   Understood !  I think the barrel burning in the 6.5 x 284 comes from the Bench Rest folks but they have issues all their own.  The origion  of my surname is Swedish , I like the idea of a cartridge that has a good following after 117 years, & with what you have pointed out  I'm sure I see a 6.5 x 55 in my future !   8)  Jim

I was just wondering if this project could have been done with 2 different barrels. Like a 223 barrel for the new chamber to be cut and a barrel from another ( that is 6.5 diameter ) manufacturer that could be stubbed to it? Thanks Dale

As I stated in the original thread in the link I posted, Wayne doesn't do stubs, it's too labor intensive.

I was not refering to the other thread. ;) I guess it could have been taken either way. I am sure there are people out there that do stub barrels. So I would think it would be cheaper to buy 2 different barrels and do a stub job along with a rechamber job. Dale

Any recommendations on who could do the rechambering work?

Wayne York does rechambers/rebores, costs are listed on his price list, he's done several for me and a bunch more for other members here.

   MHO  ???  I'm confused as to why CPC limits their 140gr 260 Rem loads to 2500 & 2550 fps ?  Rem lists their factory 140grs @ 2750 fps, Hodgdon 140 gr reloads max @ 2755 fps, &  Nosler 140 gr reloads max @ 2822 fps ?  :o

Dunno for sure, but the 6.5x55 has more case capacity by 3gr water, so the potential for more velocity is there given the same action strength in both, and at lower pressure which makes it more Handi friendly.  ;)

   What might the "optimum" barrel length be for the 6.5 swede ?  Personally, I would like a some what heavy barrel just long enough to insure 2500 fps with 140 gr pills.

That would be dependent on the powder and bullet, my choice will be the 139gr Lapua Silver Scenar which is similar to the 140gr Hornady A-Max listed in QL, but is coated. A max load of Hodgdon 780 with a longer than normal COL at 3.225" since I'll be loading in a single shot, and moving the pressure allowance from the accepted 55kpsi to a more modern 65kpsi(same as 270 Winchester), 3000fps is theoretically possible in a 28" barrel as shown in the QuickLoad 3.4 prediction. The load has a density of 103.5% and is 99.8% consumed in the 28" barrel. A shorter barrel would dictate a different powder to work best.  ;)
