Looking for any loads using 250 grain bullet. all my research tops out at 210. does anyone have any experience in this heavier load?
my herritt is a real tack driver and since it is scoped I hoped to use this box of 250 grain spitzers on the ole reload bench.
will the rifling rate of your pistol stabilize a bullet that heavy?
Probably, at least out to hunting ranges. You just have to try them and see. I have yet to meet a barrel that can read and use the Greenhill formula, so you will often get a pleasant surprise when trying a bullet outside the accepted length range. The length of the bullet's bearing surface, not the weight, is the key, but even so the numbers are only a general guide and any individual barrel can defy them. I have a rb barrel in my m/l that shoots MaxiBalls sub MOA, a 1:12 .30cal that shoots 200+gr bullets, and seen 1:7 .223's that do fine with 45gr bullets. You have nothing to lose by trying.
I shoot a .30 Herrett, not a .357, wish I could be more help.
I shoot both the 30 and the 35 Herriett's.
The 35 at 50 yards will drive a cast bullet through a 1/4" steel plate.
Did it twice on my own gong at the local range. Man was I suprised to see the two holes in the gong.
I think I was shooting 170
Grainers but would have to look it up.
Ken.
1/4 inch is a bit thin even Muzzle loaders can damage it . We used mostly 1/2 inch steel at our Muzzle loading club and it would still get beat up.
Damage yes but blew her right on out the other side.
This is the first TC caliber with cast bullets that just went right on threw.
I have shot this plate with heavier stuff than that and put one heck of a wrinkle in it but never through.
