I've used a 405gn hard cast in front of 20gns of Trailboss for 1000fps. Only used it on rabbits so far, but would likely be good for larger game (pigs, goats).
Whatever you said...everyone knows you are a lying jerk. That's a bold assertion. Point out where you think I lied. Well?

20 grains is the max correct for that 458wm case? I acyually read that 16 grains gives a higher velocity because of the pressure spike.

In my Whitworth I use 22.4 grains of Trailboss with a 350 gr.hornady for plinking.Very accurate and its running at 1194 fps.

Are you compressing that load? I read compressing TB is really bad!???

I use AA5744 in my 416Rigby light loads for varmint shooting. Works great and the loads are very accurate.

With the shorter 350gr bullet and at the depth I'm seating it, looks like I could go up to 24grs of TB.Also IMR 3031 with the 350gr TSX at about 2300 fps is a good medium load,recoil's not bad but has some serious torque on the recieving end.

The maximum load with TrailBoss will be what ever fills the case behind the seated projectile without being compressed (as you stated in another post). The minimum is 70% of that. So the maximum load will always only ever be dependant on how deep the base of the projectile is seated in the case (and not related to bullet weight at all).

My plinking load was 20 gr of 5744 with a Berry's 350 gr plated bullet. Was quite accurate in my Charles Daly Mauser and very pleasant to shoot, though I never did chrono that load.

I load quite a bit for my .458WM.
My favorite plinking load right now is 28gr SR4759 under a 350gr cast GC. Right at 1250fps and very accurate out to 100yds.
I have a few hundred "blem" Hornady 300gr HP that I was just looking up load suggestions for, going after hogs.
I have a couple of pounds of Trail Boss and some 5744, but haven't tried them yet.
Most of my .458WM practice loads have been the Speer 400gr FP over 50gr IMR3031. Good, accurate load that won't beat you to death, but will kill just about anything in North America.

I have imr3031 and a bunch of 500g solids. I hate to see these not used. It is there a light load for 500grainers?

I have imr3031 and a bunch of 500g solids. I hate to see these not used. It is there a light load for 500grainers? The light loads for the 500's use only SR4759 or 5744. Load either 30-34gr SR-4759 or 34-39gr 5744 with those 500gr solids for a "plinking" load that will still kill anything in N.America. They will be running 1200-1400fps out of a 24" barrel. IMR-3031 is an efficient powder for full-house loads and the minimum loads for 500's start around 65gr for 1900+fps which, in my mind is NOT a light load. It certainly isn't wide open, which is in the 2150fps neighborhood with 500gr FMJ's, but it WILL get your attention!  My "varmint" load for my .458WM is a Hornady 350gr RN over 73.0gr 3031. Nice, round, 1" five-shot groups, at ~2350fps. I shot several 1/2" groups with that bullet and an old lot of IMR4198 (67.0gr), running ~2400fps. I ran out of that can and, when I bought a new can, could only get 1 1/2" groups. While bench time is great in working up a plinking load to get "trigger time" and work on the basics with your DGR, I have the most fun shooting from field positions, including off-hand once I get load work done. Hitting an orange at 100yds, offhand, is enough to put a big grin on your face! I LOVE my .458WM! Ed

350 cast and 15 grains of unique. Or sub a lead round ball. Great accuracy at 25 yards for plinking!

The 60 percent rule with 4895 makes a reasonably light recoiling load with any bullet. Use 60 percent of the max load listed. I do use dacron filler in these and get good accuracy.

My first .458WM was a 77 African. VERY accurate! I hope it goes to a good home. Ed

Yes. I do weigh it. 2 grains is generally enough to take up the space with good density.

Will the imr3031 work with the 300gr hps? Or should I use 405's?
