I am trying to work up a good hunting load for a Sav.99 in 358 win. and the RCBS 250 gr. bullet. Does anyone have any good loads with 3031, 4064 or 4895 ? Thank You

If anyone is interested, I worked up a few hunting loads for the Saeco 245 gr .358 cal mold. In the 358 Win. 34 gr. of 4895 shoots under 2 in. and chronographs at 1918 fps. In the 35 Whelen the same bullet with 36 gr. 4895 shoots under 2 in. and chronographs at 1715 fps. Both without filler.

Thanks, I am interested. I have both the mould and a 35 Whelen. If you've done anything with a 356 Winchester w/ 200 or 245 gr. cast bullets that would also advance the cause. One of the best decisions I ever made (I'm sure God helping me) was buying 2 Marlins in 356 Winchester for my boys when they came out.

The 356 W. is the same as the 358 W. with a rim. Try the load of 34 gr. 4895. It worked for me. I used wheel weights and tin 40 to 1. Adding the tin seems to make a better cast bullet and maybe a little harder. Glad to know there is someone else that shoots the 35s.

With wheel weight and tin my Saeco makes bullets at .359 in. and the RCBS is at .561 in. I used the Saeco unsized and lubed. I didn't try the RCBS but I will and let you know how it shoots when I try it soon.

I thought this was interesting. The first batch of 358 W. was made from military 308s and chronograph 1918 fps. The second batch was 358 W. cases and chronograph 1831 fps. with the same amount, 34 gr. 4895. The military cases must be smaller on the inside.

Thanks for your reply 99 Strajght.. Just for grins fill a Mil. brass up with a ball powder then pour it into the non-Mil. brass.. I had a high pressure problem once and I thought it was the Mil. brass... It wasn't as they had the same cap. which surprised me as I have always heard Mil. brass was thicker and there for had less cap.

WW brass weight 176.6 gr. and held 57.2 gr. of BL-C2. Lake City 68 brass weight 180.9 gr. and held 55.1 gr. of BL-C2. Both fired cases in the 358 W. Thats not much.

if you are a memeber of castboolits. send a p.m. to blammer and see if he's tried the 4895 in his whelen. i know he has the 35809 mold and i've sent him some saeco 248's. but i ain't sure what powders he's tried.

I have a bunch of Speer SWC 158gr sitting in my storage bins. Anyone have any luck loading up something this light in a 358Win?

I think it would be a nice plinking round for my BLR.

I just found this thread after starting a 358 thread elsewhere in the forum. What twist rate are you using with the heavy bullets and are you being limited to relatively hard alloys?

I have two factory 358 W. rifles. A Ruger 77 and a Savage 99 and they both shoot well with the factory twist whatever that is. My lead is WW and tin 40:1 and brinells at about 15 with the Lee tester. I don't think 15 is very hard. For most caibers I find softer shoots better than harder. I can get 2 in. groups or less with both rifles and have killed deer.
