Caliber: .356 Winchester
Barrel length: 24”
Powder: Ramshot- X-TERMINATOR®.
Bullet weight: 180 grains.
Start load: 43.6 grains (2400 – 2500 Ft/p/sec)
Maximum load: 48.5 grains (2675 - 2775 Ft/p/sec).LD ca 106%
Bullet weight: 200 grains.
Start load: 41.0 grains (2200 – 2300 Ft/p/sec)
Maximum load: 45.5 grains (2500 – 2600 Ft/p/sec) LD ca 105%.
Bullet weight: 220 grains.
Start load: 39.2 grains (2175 – 2275 Ft/p/sec)
Maximum load: 43.5 grains (2400 – 2500 Ft/p/sec) LD ca 104%.
Bullet weight: 250 grains.
Start load: 37.4 grains (2050 – 2125 Ft/p/sec)
Maximum load: 41.5 grains (2300 – 2375 Ft/p/sec) LD ca 103%.

Here is real world velocities I chrony'd out of mine (average) with Xterminator and a 20" barrel:

180 Speer FP
46.5 grains - 2452 fps
47.0 grains - 2490 fps
47.3 grains - 2493 fps - this load shot three shots touching at 50 yards and five at about 1.75" at 100; probably shoots better than I did that day.

200 Hornady RN
45.5 grains - 2402 fps

I shot this bullet with IMR4064 too since 've had good luck with it in the 358 Win. It shot well with 47-48 grains, but velocity was around 2260-2300. I'd still use it in the woods where shots are fairly close at deer.





That's very interesting. I tried TAC in my .358 Win, but didn't get near the velocity reported. I wonder if X-Terminator will work in that. Also, have to try it in my .356.

X-Term is slightly faster than TAC, gives full power loads in my .358 Win. without compressed loads as with TAC. It my fav .358 powder.

Another good one is RL-7 with lighter bullets.
