I know that this question will have different answers for different rifles and different powders. However, IN GENERAL, which of these two bullets gave you better, or easier to obtain, accuracy?

Dan,

I never noticed a difference in my 358 Win. Both worked, though in my BLR I ultimately opted to use the 200 grain TSX.
 
The 200 gr. Hornady SP and RN got decent groups from an early Browning BLR and a Savage M99. However, in two different Ruger M77s they were more scatterguns than groupers. The two leverguns had 1 in 12" twist barrels and the Ruger' , 1 in 16" which may or may not have contributed to the problem. I didn't do too much with 250 gr. bullets but results were similar with the leverguns outshooting the Ruger bolt actions.

The Hornady factory ammo with the 200 gr SP produces groups of just under 1.1" at 100 yards in my Rem 700, and groups of almost 2 3/4" in my BLR. I haven't tried the RN.

My BLR will produce the following groups with:
  • 1" w/ Speer 220 gr Hot Cor FP in Win cases, WLR primers and 50.0 gr of W-748 (2209 fps in the 20" barrel)
  • 1.1" w/ Nosler 225 gr Partition in Win cases, WLR primers and 35.5 gr of Re-7 (2160 fps in 20" barrel)
 
Guys, thanks for the excellent replies. I appreciate the benefit of your experiences.

I am making progress on my load development. But, it takes time to "start low and work up". I have not worked with this cartridge or some of these powders before and I don't want to take too big of a step at one time. I am working with a few different powders and two different bullets.

So far, my best results have been 1.05" and 1.15" groups. It looks promising though for sub-MOA.

In my younger days I hunted with a 35 Remington with 200 grain RN Remington Core-Lokt and a 30-06 with 180 grain RN Remington Core-Lokt. They proved to be very accurate loads in both rifles. Most of game taken (WT, fox, and coyote) were taken in the 75-125 yard range, but I did take a WT that was a tad over 150 with the 35 and to 250 with the 30-06. On deer they performed well, but have to say there weren't geared to take fox and coyote, if you were a pelt hunter. I can't see why the Hornady wouldn't do you well.

I have a Savage 99-C that was rebored to .358 and may have to give those Hornady RN a try.
