Safe in all of my guns, use it at your own risk!

Good for you, 41Gunner! I appreciate it. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Thanks, I see some very interesting data there. Esp H110 w/170's and all of the Blue Dot loads.

I badly need a replacement for Unique with my lighter loads, Unique leaves far too much carbon in my SBH.

Thanks, .41Gunner. I printed that one out. I have been using my S&W 57 for many years, and my Marlin 1894S .41 Mag. since I bought it new in 1987. A really fine combo for bustin' around out in the mountains.

Thanks for some great data...I didn't load some of my rounds for the FAs quite as heavy as yours but I may up things a bit. I posted the below over on the Accurate Forums earlier in the week.

Idaho Shooter...Try 7.0 grains of WW231. Same velocity as 8.0 grains of Unique, about 950 from a 4" gun and burns much cleaner.

Got to finally do some chronographing the other day:

Freedom Arms .41 Magnum 6" barrel that is Mag-Na-Ported

220 Speer JSWCSP/23.0 H110/1545 fps

220 Speer JSWCSP/13.0 Blue Dot/1240 fps

255 CPBC WFNGC/22.0 H110/1360 fps

300 Specialty Pisol Gear/19.0 H110/1260 fps



Same loads from a Gary Reeder Custom 5.5" Ultimate .41 Hunter

220 Speer/1450 fps

220 Speer/1200 fps

255 CPBC/1325 fps

300 Specialty/1241 fps

Competition Electronics chronograph at 6' from the muzzle. Three shot average. The extreme spred on any of the loads from the FAs gun was 30 fps. From the Reeder gun 55 fps.

No clue why the FA gun liked the 220 Speer/H110 load so well and the Reeder gun didn't. Velocity was 1546,1540,1549 for the FA and 1459,1475,1417 for the GR. The other three loads are what I would have expected the difference in guns to be because of the FAs tighter chambers, flashgap and 1/2" longer barrel even with the Mag-Na-Port slots.

You may be looking at the difference in barrel twist rate. I am sure you know that faster twists increase pressure, and higher pressure equals higher velocity. I know my 10" Model 654 Silhouette from Freedom has a 1 in 14" twist, and I have seen as high as 1780 from a 290... That is just flat out scorched!!

Thanks for the work... Sounds like any of the loads you chrono'ed would do the job with plenty to spare!!

Since the Reeder has a custom barrel, I'm not sure what Gary requests for a twist rate from his supplier...

The 300 grain bullet is really something. I need to get some more. Will try and post some pics next week.

Thanks Bob.

I am also interested in Trail Boss. There have been a lot of good reports on it. As soon as Momma quits spending money on paint for the house, I'll get to increase my powder inventory a bit.

"paint"!...that is almost as wasteful as buying shoes for the kids.... Priorities...where are their priorities....
