The only thing the two have in common is the bullet diameter. The whelen improved will push a 250 at around 2600 the STA will push the same bullet at around 3000. If I wanted to improve on 35 Whelen ballistics I would be inclined to build a 358 Norma which kind of splits the difference. Regards, Bill. | |||

Cut that 300yds to 200 yds and the .35 IP Whelen would be fine. My first centerfire was a IP Whelen and I still carry it. Cobalt | ||

Why limit the Whelen to 200 yards ? My loads with 250 gr Speers sighted 3 inches high at 100 , get to 300 with about 5 inches drop , point blank on an elk size critter . Actual shooting tests show 10 to 12 inches drop at 350 . And the bullet is still packing 2000 ft lbs at 400 yards . | |||

IM4RMEF -- I had your itch several months ago. I really like the SD of the .35 caliber bullets. I went with the .358 STA and I am glad I did. I was actually looking for a Brown Bear stopper and settled on the STA. I have wound up with two rifles, you know how when you find what you are looking for, another one comes along that you cannot pass up. One is a Winchester Custom with gorgeous wood, the other a Lilja Custom that had a thumbhole stock that I am replacing with a HS-Precision composite stock. Both rifles are real shooters. With the Lilja I am getting 3000 fps. plus with a 280 gr. Swift A-Frame bullet. They are both accurate and have brakes. I am now working up loads for Elk and Alaska next year. Good luck with your choice and good shooting. ------------------ | ||

IM4RMEF, build the 358STA! You won't be sorry. When I catch up with a good bull i'll let you know how it does on elk. | |||

<IM4RMEF> |
Phurley- WOW! What barrel length are you using to achieve that velocity? | ||
<Elliot Viker> |
I would have to go also with the 358 Norma. 2800fps with a 250 is from what I have read doable. A standard length action is all that is needed, and you can use 338 win mag brass to make the norma round. I can get just under 2700fps with my Whelen improved. It packs a lot of punch for an -06 based round, and I feel that with 225's and the nosler, it is a 300yd gun. You will like the 35's, I do and just purchased a 358 win for a little brother to my 35 whelen yesterday. Perhaps a 358 norma is in the works in the future for me also. Good shooting. | ||

I'm also a big fan of 35's, and have a 35 whelen ackley. Realistic velocities are 250 @ 2600 for the AI, 2800 for the Norma, and 3000 for the STW. Since you're considering a wildcat, you might want to consider a 2.5" long 404 based 35, would have the case capacity of the STW, but fit a std action. I'm considering building one in the future. Anyhow, for your criteria, I'd say either one will perform pretty close, the STW will produce alot more recoil, but inside 300 yds, either will kill the largest critters effectively, and I'd lean towards using the 280 gr A-frame in the STW, to keep the velocities down a bit. For big bears, the 280 a-frame at 2700 would be my hands down choice, though I don't think a 250 @ 2600 would be inadequate, just not to my prefernce of a bit more bullet then a bit less. For the 35 whelen ackley, I'm partial to VV N550 and 250 gr a-frames, though Reloader 15 and Varget also work well. I've heard the hornadies are a bit soft, so I'd stick with the a-frame, partition or X-bullet. I also enjoy shooting cast lead bullets at moderate speeds for no recoil big grins practice loads. Unique and 2400 are good powders for 150-200 gr cast bullets at 800-1500 fps. | |||

IM4RMEF, mine has a 24 inch barrel and i get 3200 with 225s, 3100 with 250s, and 2800 with 280s and that load is very mild. The 225s shoot as flat as a 300RUM but with more energy and frontal impact. I think its the ultimate all around rifle for north america. | |||

Paul H, a friend did something like that but he just took a 375 Dakota case and necked it down to 9.3 and got 3000fps with a 270 Speer. He hasn't played with it much since. | |||

Excuse my ignorance,but, what does STA mean as in .358STA? GC | ||

STA = Shooting Times Alaskan. Created by Layne Simpson who writes for Shooting Times magazine. | |||

I don't claim that a 2.5" 404 necked to .358 is anything unique, and I'm sure its already been done, at least once. I'll likely just use a 300 or 338 floating pilot reamer of some flavor to cut the body and shoulder, then go back with a necker/throater to finish the chamber. Not the ideal way to do it, but saves on getting a custom reamer made. | |||

My friend Brian Smith has done the short 35 magnum-on the 300 Ultra case,which is a 404. Cut down to 2.5 inches,he's getting 2800 FPS out of a 24 inch barrel.He calls it the 358 RUM DUMB.He plans on doing every caliber possible-this was his first.He is now making a 9.3 on the WSM case. For more info,he posts on the Handloading forum of HA quite a bit.I'm sure he'd be glad to answer any of your questions. ------------------ | |||

Paul H. FWIW I have a 35/404 reamer here but it is for the std. 2.875 case.Mark | |||

Thank you for the replys! Please keep them coming. I didn't realize what the .358 STA was capable of with a 24 inch barrel! I am definitly leaning in that direction. I hadn't considered the .358 Norma. I have 100's of rounds of .338 Win Mag brass that could be put to that use. I was considering the .35 Whelen AI for a lighter weight option but I really like the ballistics of the STA. (I realize it wouldn't matter 9 times out of 10 but I would hate to lose number 10) I suspect that the recoil of the STA will be in a totally different league than my .338 Win Mags? | ||
<Boltgun> |
I am also having a 35 caliber rifle built using the full length 338 RUM case, necked up. The 338 case is slightly shorter than the other ultra mag cases and should help with those long 280 grain bullets. Todd | ||

IM4RMF, I just got an e-mail from my gunsmith about my inquiry for a 2.5" 404 358. His repsonse was that is sounds good, and he also mentioned that he built and is shooting a 9# 358 STA, and the recoil was extreme, and this should be tempered with the fact that he is building me a 458 on a 2.5" 404, as well as a 500 Jeffrey, and is re-chambering Rays 404. He also said that most actions require bullets seated deeply in the 358 STA.
That 358/404 full length sounds like too much of a good thing I do have a sick idea for a too much of a good thing rifle, which will be a 500 AHR case necked down to 458, for what I'll call the Alaskan Varminter, the performance goal is 500 gr @ 3000 fps. | |||

IM4RMEF, I have had 3 different barrelsin 358 STA. How that came about was that a friend of mine had one made and it took it to Africa. This was a number 5 contour .72" at the muzzle on 26 inch barrel. The accuracy was quite incredible, especially fromthe pint io view of accuracy across a wide range of loads. To see if it was just a fluke I had the same barrel made and had my barrel plus hois barrel fitted to a bench gun I used. Same results. Another friend then had the same barrel made and fitted to my bench gun. Same results. All of this was quite easy to do as all actions were faced off so barrels could be interchanged. Barrels were 1 in 14 twist, .357 groove diameter and chambered with JGS reamer andusing RCBS dies. My mate had deliberately chose .357"since he is a barnes X bullet man and previous testing had shown that the chances of getting good accuracy fromBarnes X was increased if undersized barrel was used. At the sametime as this testing was done we also had fitted a 338 barrel, 340 Wby (with 1 in 10 and 1 in 12 twists and conventional freebore) and 375 H&H. In terms of the "best group with the best load" they were all about the same. But for top accuracy across a wide range of loads (including very reduced loads) the 358 STA was way out in front. For brass we used both necked down 375s and necked up 340 Wby. If there is a problem with the caliber it can be if you want to seat heavier bullets to the cannelure. The OAL is greater than the 375 magazines. On last thing. Accuracy with 180 Hornady XTPs loaded to around 2800 to 3000 with different powders was superb. Mike | |||

Gold Cup, STW stands for Shooting Times Western. IM4RMEF, my 358 weighs 9lbs. and recoil with the heavier bullets is more plesent than with the lighter, faster weights but with a properly shaped and fitted stock they are quite tolerable i think D | |||

I have a 35 Whelan Improved built by Mcgowan Rifles on a 1917 Enfield. It's a fabulous gun. I have reached 2850 fps with a 225 nosler BT Bullet. That's over 4000ft/lbs at the muzzle. 26" barrel. I am still trying to find a good 250 grain round. | |||
