Default 44 mag & 296 questions

Ive been testing some 44 mag loads in a 29-10 w/ a 6-1/2'' barrel using some 300 grain nosler JSP and Win 296 (with federal mag primers) and am wondering if im getting the full effect with this load.

I am following some data posted on noslers site with a min of 20.0 grains, and a max of 21.0. I am loading about 20.1 of 296. With this load i am getting powder (unburned? ill include a pic) in my cases, and some in the barrel. I am also not experiencing much of a muzzle flash like alot say happens with slow powders.

It will be a bit till i can get out on the range to experiment some more, so i figured id ask you all in the meantime.

Any suggestions?

Does the Nosler have a cannelure so you can get a firm crimp on the bullet?
The crimp would help with the powder issue but not completely.

Is_it_really_unburned_powder_(i.e.,_you_can_collect_some_in_a_pile_and_iignite_it)?_Or_residue_or_something?

Not unusal having some unburnt powder like you show with W296.

Besides a good crimp, make sure you have good bullet-case tension when you seat the bullet. Minimal flare on the mouth & a sizer die that sizes the case a couple thousands below the bullet's diameter.

I noticed I didn't have much case tension (seated too easy & lacked the bullet's impression in the case wall) with my Nosler 240gr .429" bullets (.430" bullets were fine). Bought another sizer/deprimer (Hornady) that was slightly smaller in diameter & that made a huge difference.

Chosin - Some unburned powder / debris is common with 296 powder. As others have said, a magnum primer, good crimp, and good case tension on the bullet will all contribute to complete burn and consistency with this powder / bullet combo.

Do not keep increasing your powder charge looking for pressure signs or a cleaner burn. It's not safe. You are already about there... I have loaded quite a few 300 grain jacketed 44 mags with 296 over the years, and you are right where you want to be between 20 and 21 grains of powder with a jacketed bullet. You are probably looking at about 1150 to 1200 fps velocity at 21 grains of 296.

You can get a little faster velocities with a cast lead 300 grain bullet, and maybe a half grain more powder.

A 300 grain bullet at 1150 / 1200 fps out of a handgun is a powerful load. If you want appreciably more, a step up to something like a 460 S&W is the way to go.

By the way, lack of muzzle flash with 296 is a good sign of pretty complete burn. If you want flash, try a 180 grain bullet with a book max load of 296 in a 4 inch gun...

Going to lead is a different load and one you won't find supported in common data sources. What might work is a gas check.

The powder is some what burnt but not completely the yellow tint gives that away.

Used h110 in the past, same powder. I got tired of the granules and went back to my favorite magnum powder, 2400, for all my magnum needs back then, 357 Mag, 41 Mag and 44 Mag. In 44 Mag I never used a bullet heavier than Keith's 250 gr SWC. My 2400 load was 18.5 grs with both 240 gr SWC and 250 gr Keith SWC. Got 1,200 fps from my Ruger SBH - that was enough for me.

I wanted to try 2400, but last time i was shopping for some, it was the only one OOS.

I switched to Ramshot Enforcer / Accurate 4100 ( the same ) when 2400 became unavailable . I found it to work well , so I bought 8 lbs , I like it that much . I like Accurate #9 , but it leaves a black film on the outside of the case . I wondered if that was the flash suppressant residue ?

Like Fishinfool said,you're almost there.I don't load 300 gr jacket bullets but 265 lead.One thing I found out is when you are close to the top end pressurewise,a very little might make a big difference.I've developped a certain load for 1 of my 44s(DW)during wintertime( aprox 10*F).Everything was looking ok.But when I shot these same loads during summertime(aprox 80*F)I got flattened primers.I backed off .2gr and everything went back to normal.
All this to say that if you want to keep increasing your load,don't do it by more than .2gr increments and take note of all other variables.Let's keep our sport safe.
