    158 jsp vs 180 jsp for 357 hunting

    Ok here is the scoop...

    I have other rifles in much greater calibers but this is fast becoming my go to. I have killed 3 hogs with it this week and pleased with the performance. Only one moved more than 20 yards.

    I am going to buy some bullets to reload soon and want to know if I will see a significant increase from going from the 158 to the 180? What kind of speeds are ya'll getting with the heavier weight? My 158 federal jsp are going 1850 fsp.

    I would also like the bullet to work well with deer, but I am coming across very big pigs lately and that is the priority after being charged last week.

    Re: 158 jsp vs 180 jsp for 357 hunting

    I would stay with the 158 grain in the 357 magnum, especially if shooting jacketed bullets. None of the 180 grain jacketed bullets I load can reach the speed and energy of the 158 grain bullet.

    Now having said that, if you go to a cast bullet such as the RD 190 grain TLC-FP at 18-20 BHN or the Cast performance 180 grain WFN/GC, you can push these up to about 1600 fps. That is still below book energy levels of the Jacketed 158 grain but it will penetrate deeper on a big hog, especially if it is a shoulder hit. The problem with the bigger bullets and a Marlin is having to seat then deep enough for a proper COL and that just doesn't leave much powder space.

    I cast and load the RD TLC359190. I loaded it to near max with H110. This should get you near 1600.. I have taken a whitetail, jackrabbit, and one squirrel. No hogs yet. This load is accurate and powerful. It has to be seated to about 1.597 to cycle from the magazine.

    I did pretty good with 158gr JSPs and 145 gr Silvertips on hogs, but admittedly none were what I'd call a big hog.

    Willy, I've always thought the WW 145-grain Silvertips had jackets that were just too stout for good performance from a handgun, but out of a rifle they should be awesome..........does your hog-shooting experience with them bear that out?

    Re: 158 jsp vs 180 jsp for 357 hunting

    Thanks for the welcome. I have been stalking the forum for a while gaining lots of good knowledge and tips for the rifle. Will attempt a trigger job before long.

    The hog charged because I made a shot I never recommend and never take but I thought I was close enough to make it. Hog was starring me in the eyes at 20 yards head on so put it between them. I'm not sure if it deflected or if i just missed low but it hit a little low. Bang, flop, then up she went in a death circle. She was dead, just didn't know it yet I guess. Well she came out of the thick stuff ( bout 4 yard visibility) mouth open and headed for my friend. I worked the lever and put one directly in her shoulder ( my second favorite shot placement) at 5 yards dead run and broadside. She slide to a hault just in time for me to realize I should start sweating and be worried.

    Two shots.

    The next one was one shot in the neck (1st choice for hog) Bang, flop and stayed that way.

    Third was a shot in the shoulder by a friend of mine with my rifle. She hit a bit low so two shots were required. I have no doubt the first one would have expired the hog in under a minute but it was immobile at least.

    I have a red dot site on my marlin. Makes the running and charging shots like butter and allows precision at the further end of the ethical distance and nighttime

    My late brother had more experience with them on hogs that I do. I'd just run up on one out riding the company ATV while "on patrol" on the hunting lease and kill it. Never had to shoot one twice. They performed on hogs much like a Gold Dot on deer. Enter into the chest cavity, turn the heart and lungs to jelly and most would stop just before exiting on the far side. They are effective enough that we nicknamed them "werewolf bullets" as we'd have been willing to try them on a werewolf should one show up.

    I've used the 210gr 44 Silvertip in the 44-40 and it performs very well on deer although by the time I'd starting using those, I'd gotten very fond of a neck shot. Those would blow out a couple of vertebrae dropping the deer in his tracks.

    If you're going to try to shoot a hog in the head, you need to put the bullet in the middle of the forehead between the eyes and the ears to hit the brain. Between the eyes is a bit low and you'll end up just wounding the hog. I've killed lots of hogs on the farm for butchering with a 22 short hitting them in the forehead straight on.

    Go with the Hornady XTP HP 180gn it has two crimp grooves the upper is in the same position to make your OAL the same as a 158gn. Here is the 158 and 180 side by side for comparison.

    I really don't know what works better but if you decide to go with a 180 gr and have excessive OAL, do the carrier mod listed in the "Gunsmithing" forum. I believe it's entitled "Modifying the Carrier for Longer OAL", or something like that. It's an easy, effective mod that will allow you to run longer cartridges with no feed issues.
