So I just got a 7lb jug of this stuff for my first reloading powder.

I plan on using it for .223 Remington, starting off with a 24g charge behind a 55g FMJ projectile.

Problem is, I find a very hard time finding very much information about this powder. From my understanding it is said to be 5% faster than H335, but that being said I have a hard time finding loads for that powder as well.

Is there anything else you guys are reloading with WC735? What else can it be used with?

Thanks

Where did you get the powder? I'm going to assume Higginsons. From what I'm told, they have a tonne of data for that powder if you ask them for it.

Edit: I would start lower than 24gr. Closer to 22 or 23
 
Yes I got it from higs,


10-4 on the lighter charge, I'll start low.

So I'm a little confused as how this powder is good for rifle cartridge as small as .223 but also good for .303 brit?

Wouldn't that imply it is good for pretty much all rifle cartridges?

It definitely sits in a sweet spot for medium bore cartridges, but so do many powders such as IMR4895, H335, W748, RE15, etc. The .303 runs at rather low pressures for its capacity, so it is not necessarily good to extrapolate usefulness for it to usefulness for other cartridges of similar size.

The statement about it being 5% quicker than H335 is, to me, nebulous to the point of being meaningless. Quicker in a cartridge, or quicker in a bomb? Or just, it's quicker, so I should use 5% less? Whatever, use the same starting load that you would for H335, and work up. Data for H335 is everywhere, so it shouldn't be hard to find.
 
This is what Higginson sent me regarding WC735

The only data we compiled for the WC-735 powder is for the 223 Remington or 5.56mm NATO round. It goes as follows:
Bullet: 50 gr. Hdy V-Max C.O.L. 2.250" 25.2gr. 3408fps @ 53,000PSI
Bullet: 55 gr. Hdy V-Max C.O.L. 2.250" 24.0gr. 3212fps @ 49,500PSI
" " " 24.3gr. 3253fps @ 51,700PSI
" " " 24.9gr. 3302fps @ 53,200PSI
Bullet: 62gr. SPR FMJBT C.O.L. 2.250" 23.3gr. 3062fps @ 53,800PSI

This powder is very clean burning and very efficient.



Somewhere I have some data for this powder with the 7.62 x 39 cartridge.

I use it in .223, .243, .30-30, .308, .303Br (and the Epps), and .30-06. It delivers satisfactory results in all of my rifles. Allows me to only have 2 powders in my room. That and 700X. Can't mix them up... Used it in a buddy's .300WM and it didn't perform so well. Really could not get the velocity out of it. Not sure how it would perform in one of the short magnums, though.

That's good to know. I wonder how it would fair in a 6.5x55. If it would do well I could scrap most of the different powders I've been trying.

Does anyone have any first hand experience with the 6.5x55 and WC735?

(sorry for the quasi-hijack)
 
I have used it in 7.62x39 and .223
I find 22 grains is more then enough with 55gr bullets in IVI brass to cycle my Norc M4 and puts Hornady varmint HP's and FMJ's into a sub 1" circle with irons at 25M and that's more then enough for plinking ammo on steel out to 100M.

Would really like some input on reloading for my M14 with this powder, I guess 168gr SMK's are out of the question but I imagin it would do ok with 147gr FMJ and tracer?
Metering is excellent with my XL650 and I just got a .308 caliber conversion... Really hope I don't have to try running H4895 thru a progressive powder measure :(
 
Yep, faster than H335, but almost identical to H322. It is fairly clean and very efficient. I get my best .223 velocities with the stuff. You more than likely won't have any issues starting with 24 grains and a 55 grain pill. I am running 25.1 grains with 55 grain fmj's and no pressure signs.
 
I think I'll start on the lighter side since it is my first load so I'll start with 23g and chrono it from there.
 
I use WC735 in just about every rifle load from 204 ruger to 7.62x54R. Nice powder.

I typically just look up the load for H335 and knock it down 5%.
 
I'm down to the last 16 pounds of WCC-844 (also close to H335) that I bought 64 lbs of back in the day when we could bring stuff across the border without causing an international incident or risk time in Gitmo.

It has been stellar in everything from .223 to .45-70 - I think I'll give Higginson's a call and se what kind of deal can be struck. I have to be in Ottawa in Feb anyway for the Artillery Advisory Board. might as well make the trip worthwhile...

I tried it in my swede using 95gr Vmax bullets. 39gr produced the best group, but 39.5 and 40gr had stiff bolt opening.
