hey guys i made it to the range today to shoot 45/70 handi with trailboss starting loads with 300 grain bullets didn't shoot for groups due to lack of time and making sure reloads actually fire. i'm amazed at the lack of recoil about like my 223. I'm liking the reduced loads by the way why is it if a 45/70 is loaded with a 300 grain bullet at about 1100fps it is too weak for deer but a 45 colt pistol is the stuff with the same load? Just thinking out loud. A co worker last night told me that he could catch the bullet it was too slow. I told him to consult the millons of dead bison first before catching the bullet
Thanks for everyone's help here. Now i want to loads some BP for some smoke and boom.
Gater,
I have a similar load with my 45-70 and it is alot of fun. That load will work fine for deer within sensible range. I also have a 45LC rifle and it is loaded with a heavier bullet flying at that speed. It's fun too and quite capable of killing deer. I would not recommend anyone playing catch with either of those.

I just wish people would stop regurgitating the "1000 pounds of energy at the animal garbage"... back when guys were hunters and not snipers alot of deer were killed with 25-20's, 32-20's and such... they don't make that ever... not at the muzzle... not at 50yds... not at 100yds... never. Lots of animals been killed with 'em though. So please give up the 1000 pound nonsense.

Spanky,
I don't think there's anything wrong with that rule. One has to consider a few things when using that as theory. One would be bullet material and type; cast, soft point, semi-jacketed, hollowpoint, flatpoint, etc. Cast bullets don't expand and deposit energy the same as hollowpoints do. I think the other would be caliber. I use that rule for determining the effective range of my .243 Win. That bullet doesn't have a whole lotta weight behind it for retained inertia. Kinda like comparing a .223 to a .308 at long distances. Both may kill you, but only because one has more energy than the other. Albeit, a well-placed shot into the CNS triangle will kill swiftly but, that may be a really small target to hit at a great distance. A near miss into the chest may succumb that same target if enough energy is transferred.
When considering stopping power in a PD firearm, do you feel just as well protected loading lead cast RN bullets as you do hollowpoints? I don't and the reason is due to energy expelled.
Thant's just my 2 cents worth and, like any of my other advice, is not worth anything more than what you paid for it.

Thanks, Dinny
