Are factory 348 loads as hot as it gets?


Registered Users do not see the above ad.


I'm starting to acquire lots of load data for the 348 Winchester but I am finding some shortfalls. The fastest load data I have found for a 200gr Hornady is 2,500fps. Looked on the Winchester site and the factory ammo clocks at that same speed with a 200gr silvertip. I guess I'm wondering is this is the peak performance? Are their any such things as "hot loads" for the 348 that can really boost performance?

Bill

One thing to consider is factory ammo can be overstated sometimes, like winny's whitebox 223 stuff, supposed to run 3600fps, i clocked it around 3400 or so

That's about all you can get (2500 is a bit optimistic) at the max. recommended pressure limit (about 33K). Buffalo Bore offers a 250gr. at 2250fps...seems like a poor trade, but the Buffalo load will proably get that speed. Sure is costly ammo though.

What can't you kill with a bullet of this size and weight moving along at 2500fps? Considering the required bullet shape, more speed isn't going to produce all that much flatter a trajectory.

Case shape has been dissmissed by some, but if you were to design a case to offer a lot of bolt thrust, the .348 would be in the top 10.

I know about the cost. I was at Cabelas today and a box of Heavy 348 BuffaloBore ammo was $61.99, twenty more than any other caliber. Whats that all about?

Not really trying to develope a super hot load, I was just wondering if the factory ammo as good as it gets concerning performance?

While Buffalo Bore rounds do offer high perfomance in other rounds, gaining ony 50gr. of bullet weight to lose 200fps of velocity seems like a bad trade (and this assumes a 2450fps 200gr. loading).

Yep...do think for a standard .348case, that Hornady data is as good as it gets. It's what gained the .348 it's reputaion as a short range woods-wonder, and from the people I've talked to who used it, it's a well deserved reputaion.

I just wasnt sure if it was one of those cartridges like the 45-70 that excel as a handloaded proposition. All is good I guess, as factory ammo matches well with factory 30-06 ammo. Thanks ribbonstone for your insight.

Bill, the person that I purchased my 71 Winchester from spent a lot of time developing and testing loads for the .348 WCF. His tests with WW 200 gr. Silvertip showed an average velocity of 2484 fps, with the Chrony at 10 ft from the muzzle. I have not corroborated these test, but have no reason to disbelieve them. He was very thorough, indicating ammo lot numbers, day and time, as well as temperature at the time of firing.
