We have a new development for the 348 wcf. We will be adding this load to our for sale ammo inventory.
Case - WW Super
bullet - Bullshop Bullets 310gn flat nose gas check
primer - RP 9 1/2 LR
powder - 55gn IMR-4831
velocity - 2051, 2043, 2046 Average 2041
energy FP - 2893
notes - good accuracy , -- incredible penetration in dry wood , -- well within sight adjustment range at 100 yards.
This should make an excellent timber load for anything big!

At first I missed a 310 grainer.. brain read 210. But a 310 gr. at 2000 fps should go through most any critter anywhere.

Definitely !!! Both the 33 Win and the 348 Win use a 1/12" rate of rifling twist. If you use the Greenhill formula to calculate minimum twist for bullet length you find that this bullet length at 310gn in 348 caliber is well within the stability range. Both the 33 and 348 wcf cartridges with their 1/12" twist will handle bullets much longer/heavier than anything that was ever offered in factory ammo.
Maybe you didn't notice that we are also offering a 245gn bullet for the 33 wcf as a loading component as well as in loaded ammo. 33 wcf ammo is a good selling item for us with either the traditional 200gn bullet as well as our new 245gn bullet for that caliber. I am pleasantly surprised to find that as relatively unheard of as the 33 wcf is that it still seems to be popular with a segment of our shooting populist. There must be a high survival rate of original 33 wcf rifles. To my knowledge there have been no replica guns produced in 33 wcf like has been the case for the 348 wcf and that to me seems a shame because the 33 wcf is a well mannered cartridge well suited to most American hunting.

We like our 33 Win. At least I do. Our's is a take down with a 45-70 unit with it. But the 45-70 unit seldom gets shot by me as we have a 86 Light Weight in 45-70 that I shoot. A 245 gr sounds like a very good option for the 33 Win. I am of the heavy for caliber lead shooter.

Higher projectile weight translates to higher retained terminal velocity which in tern translates to wider deeper wound channels. To fully understand the effects of terminal penetration of expanding and non-expanding projectiles would require a full semester collage level course of study. There is so much involved that most never consider.

Bullet Master I wonder if you could post a load you might have the recipe for, with that 180 gr .bullet you offer?

Going to have to give 4831 a try in our 33 Winchester with heavy slugs. I do not remember the heaviest .338 we have in the 338 box. Must be something around the 250 grains as I am getting ready to get our .338/06 barrel mounted to our Mark X receiver when / if we can get north mid August.

Bullet Master I wonder if you could post a load you might have the recipe for, with that 180 gr .bullet you offer? I haven't spent any time developing a full power load with that bullet but I did work up a fun shooting load using 21.5gn Alliant 2400 with Styrofoam packing popcorn as a filler. Its a very pleasant to shoot accurate midrange load. |

I will give that one a try in the 33 also.......... maybe cut it back to 18gn and start up in 1/2 gns. A 180 gn FN slug hugging along at 1500-1650 fps will put the big hurt on any critter at 50 yards and less.

I will have to check my books but I think I am loading the RCBS 33-200 in the 33 wcf with 21gn 2400 but the filler is not needed. I will try to remember to check on that and get back with my recorder load.

I have used 270 gr and 300 gr bullets successfully in the .348 Ackley Improved. With the right
bullet, 225-250 gr weight is ideal for the 348 WCF. An Alaskan moose only required 1 270 gr shot
with the 348 Ackley. Its performance is almost identical to the 35 Whelen.
As an added advantage, the Winchester M-71 is a fast handling rifle for repeat shots.
That may be important for a rifle in bear country. It also holds up very well in extreme cold weather conditions.
