44 magnum 300 gr load

[300WSM]

I need some data on the 300 gr bullet out of a 7.5 super blackhawk.


Winchester site has 296 powder but the 300 gr bullet is a hornady XTP.

Can I safely use that 300 gr XTP data on the Nosler 300 gr bullet and the same powder?

Thanks in advance for any and all replies.

300WSM, welcome to the forum. I would feel pretty comfortable using the Hornady data for the 300 XTP with the 300gr Nosler. H110 or W296 should work out pretty well.

Let me know how you make out with your 300's. My front sight on my 7.5" SBH isn't the right height to zero the 300gr bullets, so I am stuck with 240's or maybe 270's... I am bottomed out on my rear sight right now for the 240-250's. It shoots great, just not enough adjustment. Scotty

300WSM,

Welcome to the forum, glad to have you here with us.

You can use the Nolsler 300gr load data for the Hornady 300 gr XTP. Just remember to start low and work up.

Yep; remember that H-110 & W-296 are the same powder, so Hodgdon's site should have some good data for you.

I'm using 21gr H110 for my 270gr soft point load. It works great in both my S&W 629PP and my Marlin 1894.

 

[Guy Miner]

Hodgdon lists a max load of 19 grains of H110 or W296 with the 300 grain Hornady XTP bullet.

That load produces 1325 fps, at 38,800 cup, according to the Hodgdon web site.

It's a load I've used myself, with several different 300 gr jacketed .44 bullets.

Regards, Guy

I'm rolling 21.0grs H110 + 310gr WFNGC from my 4 5/8" SBH. Velocity is over 1200fps, accuracy is always 2" or better at 20yds seated with elbows rested on my knees, recoil is brisk to say the least.


17.5grs of 2400 is very accurate with 300gr jacketed bullets also from my SBH. It is very accurate and not near as snappy as the H110 load.

I experimented with the 300 gr .44 bullets in my 44 mags a while ago. They shot great in my Ruger 44 autoloading carbine which isn't designed for bullets heavier than 265-275gr according to Ruger. Very accurate and hard hitting @ 100 yds.

However, when fired them in my Ruger Super RedHawk they shot so high that the point of impact could not be corrected with maximum sight adjustment. Eventually, I bought a taller front sight which corrected the problem. I never really liked the tall front sight and it did tend to drag in the holster a bit. In the end, I put the original front sight back on and returned to using standard weight bullets in the revolver.

If you need more penetration that the 240 jacketed bullets will provide just use a 250gr class hard lead bullet like those offered by Cast Performance, BearTooth Bullets and others. Those bullets will far out-penetrate any jacketed bullet IMO.

By the way - I also tried using the Barnes X bullets which I like in some other applications. These XPB bullets are so long that you would have to use their 200gr version in order to have enough room in the case for a full powder charge. Even the 225gr XPB required a compressed powder charge, which is not a good idea.

Just my .02

Charlie, where did you get the taller front sight for your Ruger? Just wondering as I have a Super Blackhawk and would really like to get a taller front sight to shoot 300's out of it.

Also, I am running the 250gr Beartooth WFN's in my Blackhawk now, and man, they are a great bullet. Very accurate and your right, they penetrate like it is nobodies business. Scotty

I'm not sure where I got it at the time, could have been MidWayUSA or Brownells. I just looked through all of my saved parts and couldn't find it. I would have been happy to send it to you for nothing because I sold the gun awhile ago. I'll look again because I don't remember getting rid of it.

You're probably much better off with the BT WFN 250's anyway. I'm getting ready to order some of their BT PileDrivers for my 45-70. Although, the Barnes 300gr XFP works very well in the 45-70. Double diameter expansion and 100% weight retention even when slamming into a hard dirt & rock berm. I recovered a totally distorted bullet that looked like a flattened butterfly after a direct impact on rock. I took it home and weighed it just for grins - 298 gr still remained.

 

[HeathSexton]

Scotty, what size 250gr WFNGC did you order from Beartooth? I ordered mine at .432" which is what my cylinder throats are and they lead from forcing cone to crown with every powder charge I run through it.

 

[SJB358]

Heath, I'm running .432" as well. I'm not having huge leading problems, but I'm not shooting tons of the either.

I need to find a replacemt sight for the SBH. Seems like they are scarce or something. Maybe I'll give Ruger a call this week and see what they have for me. Scotty

 

[HeathSexton]

If I fired one round of 250gr WFNGC at least 125grs sticks to the bore of my revolver.

I did the lapping kit that Beartooth sales and was all geeked up to shoot their bullets, but so far I have been disappointed.

Man, that stinks Heath. They shoot really well for me. I think I'm using 24-25grs of H110. They clock right around 1350-1400 out of my gun. Maybe take some Iosso and scrub the heck out of the forcing cone area? Don't know. No worries though, you could always shoot Swifts or the Hornady 265 if you needed a really tough bullet. I like Beartooths, but I don't like to wait! Gotta try my hand at casting sometime. Scotty

 

[HeathSexton]

I hear you on the wait time.


PM me your address and I will send you the bullets I have left I won't be using them.

 

[SJB358]

Thanks Heath! They are great bullets. Sorry they leave so much behind!

 

[300WSM]

Hello and thanks for the replies.

I don't understand what someone was talking about regarding a taller front sight.

This makes zero sense to me why a taller front sight is needed for a 300 gr (heavier bullet)
opposed to a 240 ish gr bullet (lighter).

I understand a taller front sight helps bring the front of the barrel down in the sight picture....but that is exactly the point. Why do you need to bring a heavier bullet down further than a 240 gr????????

 

[Guy Miner]

In many revolvers the heavy 300 gr bullets don't shoot anywhere near the same point of impact as the 240's & 250's.

There is often not enough elevation adjustment available in the rear sight to deal with the change in point of impact. Therefore a taller front sight is necessary.

Try a box of 300's at 25 yards, compare them to the point of impact with your 240's and it will become crystal clear. I still remember my Ah Hah! moment on this about 30 years ago, shooting targets.

 

[SJB358]

The easiest way for me to think about it is this. When you fire your 240-250 grain loads, they come out of the barrel faster, hence before the barrel raises too much. Well, the 300 grain bullet is slower, taking a little longer to get out of the muzzle and therefore, it hits higher (picture the muzzle flipping up as you shoot).. Took me a little to get my head wrapped around it as well. My SBH doesn't have alot of elevation adjustment really, so the taller front sight will help out in giving me a little more adjustment.
