.348 Ackley Improved


Registered Users do not see the above ad.


To Marshall Stanton (others welcome to reply)

I have a Browning Model 71 in .348 Win caliber and was wondering about getting it re-chambered to .348 Ackley Improved.

Is this an appropriate conversion that you would deem appropriate and/or recommend?

I was hoping for a 100 fps velocity increase with a 180 gr Hawk bullet or a 200 gr Hornady bullet. I'm trying to get a flatter trajectory for long shots (200 yds) at deer in open country.

Any comments would be appreciated. What gunsmiths have experience in doing .348 Ackley Improved conversions?

Thanks,

Ackley is easy!

Doing an Ackley conversion on a rimmed cartridge is about as easy as you can get. I recently rechambered my model 94 to 30-30 AI. As usual Ackley's claims for velocity were a bit ambitious, but the reality was still significant.

One thing I have to say is that lots of folks will tell you that AI in a tube magazine rifle is a waste of time. Not so. There are lots of bullets that work fine. You just need a bullet with enough flat meplat that it covers half or more of the primer ahead. That's my opinion anyway. I suppose it may be pure fools luck, but I've put at least a couple thousand semi-pointy bullets through tube magazines with no ill effects.

Patrick,

In looking over the ballistics for the 348 I am wondering why you feel any improvement would be needed to shoot deer at 200 yards? When sighted in at 2.5" high, at 100 yards, the trajectory will certainly allow you to hold dead-on, as the bullet will only be ~ 3" low, at 200. Clearly there will not be a lack of remaining energy, so this cartridge, with 180gr or 200gr bullets, is totally sufficient for 200 yard shots.

So, why deface a classic collectible firearm just to achieve another 100fps? If you really need more velocity/energy, put that Browning back in the closet, untouched, and buy a 358 Winchester or 35 Whelen. Both offer better ballistics, far better bullet selection and off-the-shelf ammo will be a bit easier to find. No need to mess with a classic when you can keep it pristine and spend less $$ by simply buying another gun that does what you're looking for!

Just my .02.

This would all be fine if it was an unaltered winchester, but he has a Browning reproduction. A fine gun in it's own right, but not a collector or classic. But I agree that the standard 348 is very well suited for 200 yd shots at deer.

OK, I feel a bit sheepish..

I didn't realize the Browning was a reproduction, but I still don't see the sense in making an AI change when it would be less expense and effort to buy a gun chambered for a better cartridge.
