Have a good oppertunity to pick up a 358 Norma Mag. Thinking it might be just the ticket for African plains game. Barrel lenght is 25" and gun is built on a Rem. 700 action. Any opinions on this round? No need to state better off to buy 375 in case it might be used on DG, as I already have a 416 Rem. Also might use it for AK moose. I was thinking of a 35 Whelen Ack Imp. but stumbled on to this and thought this rig is ready to go. Thanks | ||

I have a 358 Norma is is a 19" Mannlicher. Norma factory 250s leave at 2700fps. I no longer have my 350PDK (think 358Gibbs +2grs).By the time I got to 358 the gain over factory cases was small. I wouldn't bother with the AI if I wanted a 358 I'd go the Norma or the 35 Whelen. As usual just my $.02 Paul K | |||

Having a bit of plains game experience I can attest to the fact that the .358 Norma is totally up to the task. Having said that, I'd far rather see one using a smaller cartridge......338 mag, .300 mag and even the 30-06 as if you can shoot it....that's all you need. /////////////////////////////////////////////////////////////////////////// "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery."

I think the .358 Norma is an excellent cartridge. This deal sounds like a buy to me. I like the 25" barrel length. The .358 Norma is at the top of the list for a big caliber flat shooting round. | |||

Not in this thread but in others I keep hearing how much flatter the 338Wmag is over the 358N. To me the comparison needs to be done at the same or as close as possible sectional density. So that would be 225 for the 338 and 250 for the 358. To keep it simple for velocity I used the posted Federal 338 225Pt of 2800fps. I then used the 358N 250gr of 2756fps but substituted the 250PT to try and keep same bullet shape. Then used the JBM program to calculate using a 6" kill zone. For the 338wmag the max PBR was 286 yds and 2597ftlbs. At 400 the drop was 16.9" and 2360ftlbs. For the 358N the max PBR was 281 yds and 2961ftlbs. At 400 the drop was 18" and 2517ftlbs. I have a real hard time seeing a difference. The 358 has 7% more energy at 400 but the trade off is 9% more recoil. I call it a draw. As usual just my $.02 Paul K | |||

I get 2820 fps w/a 250 NP and 2975fps with a 225 NP. All with a 23" barrel. One of the many virtues of the 358 Norma is it's ability to use faster powders because of the low expansion ratio(case capacity to bore capacity). This means in my 225 gr. load I use only 69.5 gr. of H4895 which translates into less powder burned, therefore less recoil than if one is using 75-78 gr of a 4350 or 4831 out of a 338.

I don't think a 338 Winnie can launch a 225-grain bullet at or over 3000 fps. 2850-ish is the best I could get with a 26" factory tube. | |||

 I used 2800 which is the velocity listed by Federal on their site for the 225grPT.When I had my 338wmag I ended up several grs past the Nosler Max and could just reach 2800 from a 22". As usual just my $.02 Paul K | |||

I shoot a 35 Whelen AI, and it's a great cartridge, but it does'nt give you much over the standard Whelen. I do have one load with 250 Partitions at just over 2700 but most loads are in the low to mid 2600 range. Not that there's anything poor about that kind of performance, but a ready to go 358 Norma would be hard to pass up! And as the throat gets shot out you can rechamber it to 358STA. | |||
