.327 Fed Mag with H110

what primer are you using with that load? are you crimping to the bottom of the cannelure?

There are many powders listed. H110 should be the best. I have used 2400 and Power Pistol.

You using a magnum pistol primer or a small rifle primer??

This data is for the 115 Gr but the same powders can be used. I do not use the rifle primer, I use CCI SPM.

2400 is the powder I use for full power loads.
No unburned powder.

Haven't tried H110 so I can't compare 'em.

H110/296 demands a heavy crimp. That should be the first step in troubleshooting if you actually have a problem.

I shoot a 120 grain LFN with H110 and CCI mag primers sometimes, the crimp is moderate and I have no signs of unburnt powder.

If you get the itch to try something else, look at Ramshot Enforcer. I use it 90 percent of the time when going for full magnum loads in 327 Fed. It is more accurate across the board and gets velocities that are just as fast as H110. I'm not giving out data because it's not in any book that i know of and may not be safe in your revolver. And, I'm a Hodgdon lover just as much as the next guy, but I have to say the ramshot in this application is my #1 choice. I got flattened primers with the Win mag primers and didn't when switching to CCI mags. I quit using the Winchesters for magnum loads and used them for loading 9mm.

Edited to ask: what revolver are you using??

Thanks for the replies. I am using Winchester SPM primers, but I have been using a light crimp. I am seating the bullet so that when crimped I can just see the top part of the cannelure. It won't be very hard to go back over my reloads and give them a heavy crimp. THR rocks.

You will still see the top edge of the cannelure don't seat them deeper, just tighter. Don't over do it though.

I load a lot of H110 / 296, and it does burn a bit sooty, but nothing that seems excessive.

I would definitely crimp them with the maximum amount possible, and place the crimp over the bottom edge of the canelure. This helps the pressure to peak before the bullet exits the case mouth, thus provides an efficient powder burn. H110 / 296 needs it pressure to burn properly.

Glad it worked out for you.
