358 Winchester Cast Make Sense?

[TXGunNut]

Thanks for posting the pic of your beautiful 99, I guess I should say that the 99 is more than a showpiece. Yours certainly could and should be, IMHO. As you may recall I stumbled across a mint 99 last summer but haven't been able to talk Swede into doing a run of moulds for a boolit I'd like to use for the 2015 hunting season. That's OK, I have too many projects going on now anyway. I feel quite fortunate that our deer season is so long. Starts for archery in October and continues into February for certain special seasons.

Hi fellas,
Just acquired an old steel receiver blr in 358 win which I’m going to load the Noe copy of the 35-200 Boolit sized to .360. I have noticed most are keeping velocity in the 2000 FPS range. Just wondering if anyone is loading this bullet to 2400 FPS using Lyman no.2 with acceptable accuracy.
I am just trying to realise this cartridges mpbr.
Regards
Simon

I have a custom Mauser 98 in 358 Win and my load for it uses a 255gr bullet from "Mountain Molds". I get about 2200fps with accuracy of about 1.25" for 5 shots at 100 yards. With the large meplat on this bullet it is a real thumper on whitetails. My alloy is COWW + 4% added tin.

Morning High Standard.

Your alloy of COWW...are they air cooled for this load or water dropped, heat treated?

Thanks for sharing.

I have had a 358 mold for 15 years,casts nice... I wanted a 35 Whelen or 358 Win back then.

I still have the mold,even coated some boolits... But I still haven't got a rifle to shoot them with. Shame on me.

I have been using cast in my 358 for quite some time now 3-4 years
anyway I am having one heck of a time getting repeatable accuracy
oh I can get one group that will be within my accuracy parameters but then it falls by the wayside with the next group
My hunting rifles need to be rite around 1" @ 100 yds ,3 shots.... every time
don't know what the answer is I have many different boolit designs hp and non hp
some say a match made in heaven but I guess that I haven't got my wings yet

wow this is an old thread
found my wings so to speak it's powder coating
I shoot a 260 gr.Mountain Molds boolit with
40.5 gr of imr 3031 and a alloy of 16-1 get
exceptional accuracy and drops whitetail like a bolt from above

Excellent.

Coating is good,I got seriously back to casting now that I discovered coatings.

Here are my 358:s with some 458:s. 358 Win is a rare caliber around here... but an easy re-barrel for a gunsmith.

Good thread!

My 'for what it's worth' is the Hunters Supply 246 gr bullet (https://www.hunters-supply.com/359-cal-246-p-1370.html). I add a gas check just because I drive them a little faster. My rifle is a tad different....a 9X57 with a .358 bore. It shoots the HS bullet very well indeed and to POA at 100 yards when my rifle is zeroed at 2" high with my Hornady 250 gr RN bullet. So far, I've only had shots at deer when using the Hornady but will at some point use the cast on a deer.

Good hunting!
