What I need to know is who uses which powder for top end loadings?
I have some green dot and herco which could do small game cast loads and I have some H4227 that I think can do top end loads but I was cosidering some 2400 or H110.
Imputs please

Thanks Blain.BlaineG wrote:I've been using Blue Dot for high end loads in .357, and .44 Mag.....IMO, H110 is touchy, and gives you the blowtorch effect. Blue Dot burns almost exactly like the 2400, and I can get as much performance as I care to out of it...I've never been one for max loads, anyway.

H110 looks to give big onions across the range!harry wrote:125 GR. HDY XTP Hodgdon H4227 .357" 1.590" 18.0 1955 34,400 CUP 20.0 2122 42,000 CUP

Good luck Nath, when I had a .357 Rossi the Hampshire police would only allow me to use it on a range..Nath wrote:Ok guys, I am going to attempt a change to my English firearms licence and put in for a 357 carbine.

I use them almost exclusively after talking with the Tech Support lady at CCI a few years back during the primer shortages. When I told her I wanted to talk tech stuff and not complain about availability she was happy to talk. She said she'd worked at CCI for 37 years in the tech support dept and it became evident quickly that she really knew her stuff. I mentioned that I'd found that I got higher, more consistent velocities and lower SDs and ESs when I used CCI's LPM (350) primers in my hot 10mm Power Pistol powder loads instead of the LP primers called for. In addition, I found the same thing happened when I used CCI SR (400) primers instead of SP (500) in my 357mag loads and H110 powder in my leverguns.Nath wrote:I have stacks of small rifle primers.
Would they be hot enough for H110?

I asked what the difference was between CCI's SPM (550) and SR (400) primers and after comparing the specs on both she told me that CCI SPM (550) and SR (400) primers are the same size (small primers are the same size, rifle and pistol, it's the large primers where the rifle primers are a tiny bit taller than large pistol primers), have the same cup material and thickness, have the same flash powder composition, and have the same amount of flash powder.
I said that it sounded to me like they were the same primers to which she laughed and said that she reloads a number of calibers, can get any primer she wants any time, and has settled upon only a few primer types for all her handloading, SR for all her SP pistol loads, SRM for all her SR rifle loads, LPM for all her LP loads and LRM for all her LR loads as she found the same thing; higher, more consistent velocities and lower SDs and ESs on the chrono.
She said she adjusted her powder charges accordingly and agreed with me that a good starting point for loads when using magnum primers was 1/2 grain less powder than you'd start with a non-magnum primer but that it was only her personal preference and that CCI recommended that a handloader use the proper primer as called out in the reloading manual.
YMMV
