A 160gn @ 1500fps should do it. I know for a fact a 158 at 1500 will.
Not sure about 2000 fps with a .357 cast bullet if you care about SAAMI pressures, Hodgdon data maxes out at 1757 fps for a jacketed 158 grain bullet. Of course some folks believe that if the gun doesn’t blow up then the load is safe….
Higher the speed the better.
A great big meplat is your friend. Even if you don't get expansion you will transfer lots of energy.
A few years ago I shot a doe at 80 yards with a 198 grain bullet doing around 1900 fps at the muzzle. Only a 308 cal bullet, but it had a .19 inch meplat. Made a good hit in the vitals and that was it. My alloy was about as hard as op's and I appear to have had expensive as the exit hole was nickel sized.
What powder do you plan on using? This will effect velocity goals more than anything.
My suggestion is H110. There are several others that come close to it though.
My 20"Rossi will push 180s into the 1900s without leading. But I'm running 360 DW loads.
I get 1870 with 158s and h110 at 357 seating depth.
Gas checked swc design. I have lots of different powders on hand but was thinking of using 2400. Shot a few yesterday at around 1700 fps but started getting odd flyers at 50 yards. 1500 and slower were accurate. These loads were Hodgon longshot powder. Appreciate your replies. My mistake it was lilgun powder NOT longshot. Sorry. Top mv was 1885 for 5 shots. Flyers started at 1807 fps.
Good luck, let us know how your hunting trip turns out.
Why would you? Curious as to why thank you
Lilgun is an oddball in 357. It burns very hot and that may be causing you issues with a lead bullet. 2400 however is practically made for what you are doing. I have had really good results with it in 357 and even used it for 3006 cast loads.
I agree. But I have had good results from lil gun also. I've had bad results as well though.
I always try a different powder if the other doesn't do what I want.
There was no problem except accuracy when the velocity got high. My first 3 loads where pretty good.
Note that down in your load book. Try 2400 and note it down. The better one is your best option.
Yeah, and you clearly have a good option for deer with lil gun. I'd still give it a try with 2400 to see if you can do better. You are using a rifle that is kind of marginal for deer, so I would want it to be all that it can be.
I fooled with lil gun and Sierra JSPs in a 24" Rossi a few years ago. I found that even the book max charges were very accurate. I didn't chronograph it as 357 isn't legal for deer in my state. Given that I could push jacketed bullets much harder with accuracy that you could with cast makes me suspect that the high heat of lil gun's combustion may be an issue.
Try some different powders if you have them to see which gives you the best velocity to accuracy ratio. Slow powders will work better for that, but some have been perfectly happy with powders like Unique or AutoComp.
