I'm new in this forum

I read a lot about the 500 grains bullet in 458 lott but I would like know more about 350 grains or 400 grains for plain game, could you help me in this matter? I refer to velocity and bullets.

thanks in advance

thank you very much for your answer

Ibex,

I shoot a 45-70 a lot (also .458 caliber) with 325gr bullets at around 1900 fps. I have yet to find an animal in the U.S. where that bullet stays in the animal. I also shoot a 430gr hard cast lead bullet (non-expanding) at around 1800 fps that is quite unstoppable on medium to large game (wild boar up to elk). The 325gr load I shoot is good out to around 200 yds (at least that is where I am comfortable shooting it), and the 430gr load I am comfortable shooting out to about 150 yds.

Seems to me that if one were to load 350gr, 400gr and 450gr bullets in a 458 Lott, it would do very nicely on any game. I think one could get a 350gr bullet up to around 2600 fps out of a 458 Lott. The way I see it that would be a good round to shoot anything out to 250 yds.

Hope this helps ....

I should have said - "shoot any plains game out to 250 yds" - the 500 gr loads are obviously what one would want to use on dangerous game ..... :eek:

I just took my 458 Lott up to Cape York (far North Queensland in Australia) and shot two scrub bulls and a few pigs with it using thin jacketed 405 gr projectiles made by an Australian company. Shots were taken from 30m out to around 130m and it performed very well. The only issue I have with the 458 Lott on medium game is that it is a little too much gun at both ends, I had a couple of pigs I nearly turned inside out, one shot through the chest lengthways was missing a fair bit of his hindquarters. That said, African plains game would generally have a thicker hide than an aussie feral pig so the issue would not be as much of a concern. I took the 458 for a bit of fun, but tend to think I would take one of my lighter recoiling flatter shooting rifles for an African plains game hunt.

Cheers

velocity in mine was kept down to a tad over 2300Fps with the 405 gr load

..I think Bangflop has the right idea there! I've never shot the 458 lott but shooting thse 2 bullets out of the 45/70 are quite deadly on any game! You throw a bullet the size of a small missle with lots of energy behind it, somethings going down! with those velocities the lott may even be quite comfortable to shoot vs. loading it to the hilt for dangerous game!

Its still a little uncomfortable to shoot, although it recoils alot less than it does with the fullpower 500gr loads.

With a 405gr pill loaded at 2300 Fps you are still a good 300-400 Fps in front of a 45/70 depending on the rifle/load. That said, most 458 Lotts are heavy rifles and the recoil out of a marlin guide gun can be stiff to say the least!

It is no trick to get 2600 or 2700 fps (chronographed) with a 350 grain TSX and a plain old .458 Winchester and H4198 with acceptable pressures from my 22" barrel. What you do is crimp on the second groove, not the first one. The round will fit in a Model 70 magazine. With a CZ550, you can crimp on the third groove and still fit in the magazine. This effectively increases case capacity.

Note that the .458WM also has a lot of freebore for some reason, effectively increasing case capacity as well.

The 2700 fps load gives 5700 foot pounds at the muzzle. I've calcualated (but not verified--note that Barnes balistic coefficients are suspect) that this "pointed" bullet load gives 3000 foot pounds at 300 yards. Trajectory is within a gnat's eyelash of a 30-06 with 180s.

Sort of a .375 H&H on steroids.

i haven't played with loads for a 458 Lott but i have played with loads for a 416 RM and in my experience you can get roughly 200fps for every 50gr of bullet weight loss with the H&H cartridge family. i use a 300gr bullet at just over 2650fps in my 416 RM and have been very pleased with its performance as a PG rifle.

if your getting 2300fps with a 500gr bullet then i would expect roughly 2700fps from a 400gr bullet and roughly 2900fps from a 350gr bullet. however, you may run into a problem with your rate of twist. a 350gr bullet is MUCH lighter then your 458 Lott is meant to fire and you may find accuracy issues due to the bullet being much too short.

Thanks for the info , I would never take it too 2700fps or 2900fps .

MOA is critical with a reduced recoil if possible .

not sure what kind of accuracy you would get with a light bullet moving that slow. in my experience it doesnt usually work out that way unless the gun is built for it. i believe it has to do with the rate of twist in the barrel (but i could be wrong).

you can always try it and see if it works out.

no experience with 350's so will keep an eye on this thread - please update with your results , should be good! I load 450Grn TSX on the Lott and they work very well (I run them at 2450Fps , can probably push them faster but no need IMO) they are reasonably flat out to 200 (I do not need more than that) and are very accurate out of my Kimber and they hit like Thor's hammer on PG (Eland , Oryx , Warthog & a Duiker (Used a solid for the little guy)

I shoot a lot of 350gr Hornady RN in my 458Lott as a practice round using 60gr IMR 4198 going out the end of the gun approx 2200fps, I's sure with a good quality bullet and a bit more powder you could have some fun..

zephyr - Do you use any filler in the case with the 350's?

Hello! I noticed your E Type in your avatar. What year is it? I have a '69 that looks identical, minus the wire wheels. My car has the steel rims, as I understand it,a more expensive option, but I like the wire wheel much better!
