Campro has an updated website now. If you email them, they will send load data......
I highly recommend you do this.
Load data should be right on the site now for download.
question on 357mag load with campro and hs-6

Load data should be right on the site now for download.
I am about to start loading 357 with h110 SRP and SPPM, I have the 158gr Campros and 125gr as well. I'll let you know how things go. I am aiming for foractory velocity, so around 1250fps. I dont need to be heading in the 1400+ range. thats a bit much lol.
they don't have all the data for the popular powders online. for example, I just got the data below via email which you will not find it on their site.
Load data for 357 (looks like campro just use the same data as the hdy xtp data on hodgdon's site)
w231 125gr 7.3gr - 8.5gr
w231 158gr 6.2gr - 6.9gr
44 spl (this data is not even on hodgdon site)
w231 4.2gr - 5.2gr

Oh wow. the only thing is, do they know what kind of velocity that will produce?
Hodgdon says 15gr for h110 for 1400fps. would it be safe to drop that to say 12gr? for a starting load. I dont need that hot of a 357.
no. there is no such info from campro. If I have to guess, given so many data from campro are the exact same as hdy xtp on hodgdon, the velocity range should be close? for the exact number has to be chrono'ed out as guns are all different anyway.
as for your h110 data, I couldn't find anywhere that says to go that low(12gr). And from what campro says and my own testing on the hs-6 data, their range is NOT hot at all. as mentioned in earlier post, the hs-6 top load is still less recoil than the federal AE factory ammo. So, I wouldn't be worry too much about 15gr being too hot. And the rule of thumb for reloading is that you don't want to go over the max, but can go below the minimum until it can't reliably fire. I think 14.x might be worth to explore, but not sure about any lower. And come on, we are talking about magnum rounds here, what's the fun if there is no recoil. Lol...
Just speak from my limited experience(and mind you that I never use h110 before), I always start with the recommended low end, and experiment towards both ends, upward to the max, lower to the gun can be reliably fired.
just an example, when first loading for my 9mm(with hs-6) and 40(with longshot), that's exactly what I did, but eventually, I ended up below hodgdon's minimum on both rounds as they are good enough for me as I am only shooting indoor up to 25 meters.
so, have fun experimenting.

Great information. Thank you.
I tried 7gn of 231/hp38 with a magnum primer, as per the load data. Not bad but not enough umph for me. Next on the block is 15gn of h110. Ill see how that goes as well.
I am also going to experiment with small rifle primers. I shot ten SRP in 38 with my gp100 and they worked well. Decent grps as well, and no pressure issues.
I am going to see how the starting load of 15gn goes with SPmagnum primers then try a few loaded with SR.
Should be fun!
