I just received 67 lbs of boolits from Penn. Forgive me for not casting my own, but I simply don't have the time to get into another hobby. However, I do enjoy heavy lead.
So, back to the issue...
I've got a 15" Encore in 460 S&W. It was probably the wrong caliber for what I wanted but it's what I've got. This thing was an unholy beast with high powered jacketed stuff.
Now, I'm trying to find a way to lob 300 gr lead around 1300 fps so I can slam a ram or two with reasonable accuracy at 200 meters.
Looking over my notes, I tried Cast Performance 335 WLFN over 14.5 gr of Trail Boss. This required careful loading to prevent compressed charges. This load is the absolute maximum for this bullet and this chamber. It gave me 1040 fps.
Stuffing 250 RNFP over 12.5 gr of Trail Boss rewarded me with 1200 fps.
What are the chances that a full case of uncompressed Trail Boss will put the 300s where I want to be? If it won't do it, what powder should I be looking at?
I tried a starting load of 20 gr Power Pistol under the 335s and that gave me 1580 fps which is a little heavier recoil than I wanted.
I really want to run the 300 silhouette bullets. I think the shape and caliber/length ratio will make it easy to get up to speed and keep that speed during flight. Again, after 200 meters it can drop like a rock for all I care.
I thought about Casull type loads with fillers but that idea really bothers me. It seems like a long way for the burn to go before it has to start making pressure.
For those who have never messed with the 460, here's a pic of a 45 Colt, 454 Casull, and the 460.
The case capacity is larger than a 308.
