Very nice!

My 4.6" Lonewolf barrel has a bit of free bore. I need to get back into handloading. I'd like to set the bullet out against the lands to make more room for powder. Can extra speed be achieved, such as 1300+ for a 200 from the 4.6, or does pressure put a stop to it?

Hey Overkill, one thing that comes to mind is by increasing the COL you tend to loose some bullet case neck tension to aid in powder ignition and burning.
I have seen 1265 from the G-20 factory barrel when developing loads for the Speer 200 grain Gold Dot that were sold as pulled bullets from a contract of 40S&W.
Started to see a little primer smear with that load of 9.4 grains of Longshot.

Your gonna run into issues with a long OAL with the Glock magazine before you ever reach the lands.

Other WFN bullets with a meplat larger than 0.30" have to be seated deeper in order to work in the mag. The larger meplat actually makes the rounds bind because of the geometry involved. You can actually strip rounds off the magazine with your thumb and feel the loss of tension after the 5th or 6th round. This obviously causes jams when the mag is full.

However, earlier this year I got the mihec mold from a group buy from the castboolits guys. This design has a 0.30 meplat so now I can load to 1.250" and not jam. I recently sent the mold to Montana Bullet Works and now Bruce is casting them but they are not on the website yet. Just give him a call and ask for them.


I think it's possible to get a little more velocity but I'm not obsessing over it. It's very likely that even out of a 4.6" barrel the 200 gr bullet will still be north of 1200 FPS.

What about from the Ruger Redhawk? What do you think could be ahieved?

Theoretically I suppose it's possible but why bother. If I had to cross over to a wheel gun then it's time to switch calibers and go with 44 mag or larger where the ballistics are better for the same weight gun.

A four inch S&W 686 (357) or 629 (44 mag) weighs about 42 oz unloaded.

A Glock G40 is 44.62 oz with a loaded mag.

The overall length for all three guns are practically the same so they all carry about the same on the belt.

You carry the Noslers just for the woods or normal human defense?

I carry the Noslers for human defense. I carry the XTPs for woods defense.

That 10mm Glock must pack a sharp recoil whack, I have the G22 and it's my least favorite semi shooter. My G22 packs a sharp recoil slap, and for some odd reason I get an annoying trigger slap after about 3 mags fired. My wife on the other hand enjoys the G22 so it's a keeper.

No...

That added weight of the long slide tames it right down.

220 grain at 1246....that's thumpin' !



In this monstrosity theres next to no recoil either.  Ive pushed the 220s much harder with 800x but ill refrain from posting my crazy loads because a comp is truely needed at that level.

Gorgeous rig!

I truly love the 10mm. I know the revolver cartridges are more powerful, but it's hard to beat the 10 in practical size handguns. It can truly be a 357 Mag in semi form.

As some of you know, I just got the 41 Magnum Blackhawk, 6.5 inch barrel.

I just ran some Hornady factory rounds (210 XTP's) over the chrono and thought the results might be interesting to put in this thread.

The 6.5 inch 41 Mag averaged 1,300 fps with the 210 grain bullets.

My G40 with the 7 inch barrel...... averaged 1,300 fps with 200 grain bullets, using current published load data, and could have been pushed a little harder.

If that is not proof that a properly set up 10mm can genuinely get into 41 Mag territory then I don't know what is.

I know there are hotter 41 Mag rounds to be had, but I consider Hornady to be pretty decent ammo, and not just range fodder like WWB or Walmart Remington.

Underwood 10mm is a good bit hotter than my reloads.

Ramjet

41 GNR which is a 44-mag brass reduced to 41 will run much faster, my Blackhawk from Reeder is a real boomer in 41 caliber. I like the gun I like the power but not near as much as my 10mm.

I will agree you want 41 mag power then buy a 41 magnum. I remember years ago I had one in a S&W Mountain Gun  it was nice carring handgun but hard to handle full power.

I am actually looking to go the other way heavier lower velocity Hardcast for hunting.

High velocity lower projectile weight for self defense. (commercial loads)
