Thread: 358 Win load help and sggestions

I'm about to start loading for my 358 win. I have dies, made brass from 308 cases, ADI 2208 and trailboss. ( my 243 powders are W760/H414 and supreme 780)
projectiles are 225 game kings which i gave plenty of load data for and

The mystery I need suggestions for is the 357 cal Hornady 158 gr XTP hollow point.
I have load data and COA length info for 180gr sp and 200gr flat nose but the COA is way too long for the XTP's.
I'm thinking of aprox 48gr of 2208 and loading the bullet to the base of the neck still short of the ring around the bullet.

Only looking for aprox 2500fps as that way they will shoot to a similar POI as the GK's out to 200mtr.
Goats, fallow deer, fun shooting etc. Game Kings for tougher animals and out to 300 mtr.

Ps. why the XTP's? Bullets are less than half the price of the game kings. Want something light for small game (goats) and easy on the shoulder.

I've got some hornady 200grn round nose designed for the 358win you can have and some 357 180 Hp's. I'm in mangawhai.

Let me know the COAL you propose to use and I'll run it in Quickload for you.

Thanks Tentman

Data for 358 Win
Bullet 158 Gr
COAL 2.3" - 2.4" (Short)
ADI 2208 (Varget) 48 gr
Barrel 20 "
Action Savage 99 (1975 308 rebarreled)
Target velocity 2500 fps

Was looking to keep the OAL length as long as possible but these bullets are short compared to the larger Spire points.
Hornady 357cal 158 gr Hollow Point XTP Bullet BC 0.206 is only 0.671" (17.05mm) long.
Cartridge OAL somewhere between 2.3" - 2.4" (58.5mm - 61mm)
That gives me 6.4mm to 8.8mm of insertion into the neck of the cartridge.
I have got load data from Hodgdon, Lee, Accurate & ADI. It all looks like they got it from the same source.
180 gr Barns and 200 gr Hdy both have a min of 47 gr and a max of 51 gr compressed for a velocity range of 2400-2600.
I dropped 51 grs in into a case and it would have been 3mm from the mouth. How much compression is acceptable.

Thanks

mate in sweden uses them for that very reason(cheap cheap specially in bulk).....in a laminated model 7 no less.... beautiful rifle and the BIG european hogs he knocks over with it dont seem to mind.

Hi Tentman,
That's great. Thanks for the information and guidance.
Those number bear out what I was thinking and experiencing. I could not see how 51 gr was going to fit.
Usable case capacity of 49.6 gr looks real.

Looks like I will have to go a grain hotter up to 49 gr to get the 2500 fps I was after.
The nice thing is that the Chamber pressures will be well down at 40,000 psi so I won't be giving the action too much of a hard time.
3.75" high at 100 mtr with a 200 mtr zero.
Virtually the same as the 225 Game kings if I can get them to 2400 fps (staying under 49gr of powder) but the GK's hang in to 300 mtr only 9" low.

Thanks again
Zq

I shoot 225gr serria, with 49g varget for a hunting load, factory Hornardy 200gr are same point of impact at 100m.
I didn't have much luck, with the 140gr and 158gr so far, low and to the left 2-3" at 50m, I was using 15gr trailboss. biggest problem is, I can get consistent feeding from the magazine, with blunt nose pistol bullets.

@Micky Duck there called “Boar” over here old chap
You want “Hogs” go to the Sates
Yep .358 dose a really nice number on them.

pigs.poakas.gruntasaurusdeloris/boris.hogs.porkers. all the same thing and a boar has nuts a sow has tits and a barrow (doesnt have one wheel and two handles) was a boar but has had a wee operation so now has no nuts.
they all make bacon mmmmmmmmm bacon.

Well got some rounds down range over the weekend.
158's with 49 gr and 225 with 48 gr of Varget / 2208. (Did try up to 48.5 with the 225.
All worked well. No issues with extraction on the lever etc. Could even re chamber the fired brass just about all the way. (my 243 lever stopped well short without a full resize)
Only issue is that the 158's are well to the left of the 225's. Some more range and chronograph time required.
The 225's definitely have more authority to them at the shooter end of things.
Need to pay more attention to holding the stock to avoid scope eye with them as well. Had a near miss or 2.

To added to that those are just the English words let's not get into French Spanish Italian Turkish........

Had the 358win out again this days off, for a ruger it can sure shoot,
horrible gusty windy day, fun whacking the gong, with the 200gr round nose, sure make a splat,
50g varget and 225gr, very accurate for a thumper. 2450fps.

200m, 50mm gp with 225gr, 60mm with the 200gr FTX I am just starting to play with. 50gr varget giving 2525fps, probably need a slightly faster powder.


Its pissing me off, that the pictures turn sidewise.
