Big Bore Handgun Heavyweights Update

I do like the sounds of lower velocity like your talking about with my 460 and I know there are concerns with these slow burning powders being reduced. What would you recommend I try as far as powders with this 460 8" barrel...to get the lower velocities without concerns for a squib. I will take any suggestions as I will always safely think out anything I try. For the time being I will stick with published data as I don't get out to shoot as much I would like.......like every day if I had my way, LOL.

Maybe I need a shorter Barrel for the lower velocities? Just a thought.

EDIT: Maybe the high velocities go along with the "Gain Twist" 1 in 20" rifling of the XVR. But still I need my own test shooting time to determine what it can do at different velocities, as far as accuracy goes.

I found this related to light loads in large cases>>>>>http://www.reloadammo.com/liteload.htm

.41s....

I have done quite a bit of work with 'heavy" .41s in the 250-300 grain weight area. Have had no problem with accuracy at 50-100 yards with Ruger, FA or Smith revolvers.

This is a picture of a 255 CPBC WFN-GC that was fired at 1300 fps. It penetrated 6 gallon jugs of water, one 3/4" piece of Marine plywood and then burried itself to the base of a 4x4" post at the end of the test area. A 265 grain did the same thing but I put up a second piwce of 3/4" marine plywood and it made it through both pieces before ending up deep in the post. Load was 22 grains of H110 for both bullets.

As to lightweights having no penetrating power whoever tells you the old no longer produced Speer jacketed SWCs expanded but didn't penetrate they don't know what they are talking about. Most .41 Magnum JHPs end up in the second or third jug of water...the 200 and 220 zip right on through. This is a 200 grain HP at 1400 fps...6 jugs of water, punched through the first piece of marine plywood and stuck into the face of the second piece....

Last weekend I was shooting some 305 grain .41 LFN-GC bullets that I was sent from a caster in the Houston area. With 19 grains of H110 the velocity is in the 1200 fps range. Penn Bullets also sells the original SSK 300 grain bullet and with 19 grains of H110 it is also very accurate and penetrating. It is more of a truncated cone design, like a silhouette bullet vs. the other 300 that is a wide flat nose LBT design.

Was shooting this bullet from a 5.5" Gary Reeder custom Bisley and a 20" Marlin CCL.

This was 50 yards with the CCL from the sitting position with the 255 CP bullet. The 5 shot groups using the 300 last week were just as tight...

The only problem I have with the heavies is that often a new higher front sight has to be added. Had to that with both the FA and Garry Reeder to make them shoot POA at 50 yards... The Rugers and Smith I have will not shoot anything over 250 to POA at 25 yards...way to high.

SuperMan,

That's some interesting testing you did there and some nice guns to boot, thanks for sharing.
 
Scrapper; I know nothing about the 460. I am in no position to give you loading advice for that cartridge...so I wont, but, I am sure there are those on this forum who would gladly help you out....Post your question as a new thread and I will bet you will have all the answers you want.
 
Superman; It would be interesting to get penetration comparisons of your 255's and 300's at 1000 fps or so, and see how that performance would measure up to what you have already done. Most of us are coming to realize that high velocities do not always equate to maximum penetration. If you get a chance to do a comparison...please post your results here! I am sure that ZAN would be interested in your 41 Mag results.
