458 Lott 730 grain

[HollandNut]

I may have the same boolit for the Lott , forget where I got the mould from , but it looks like a 750 grain wadcutter .. See if I can find the pic .. I had a 462560 four cavity that I sold to wiljen several years ago , it's a hoss also ..
Same rifle Safari Classic with a European stock on her ..

. This is the Lyman 462560

Here's the Matt's bullets 730 grain.

[lar45]

Matts Bullets 730gn .458 bullet is 1.690" long with a .720" nose. So looking at a loaded length of 3.52"
This is only for Matts Bullets, if yours is a different length or has a different nose length, then this won't apply...

Below are Quickload max loads, so reduce and work up checking velocities.
RL-15 65gns 1812fps @ 62kpsi 101% load density

RL-17 67gns 1760fps @ 48kpsi 100% load density

IMR 3031 60gns 1759fps @ 60Kpsi 100% load density

H 4895 62gns 1780fps @ 61kpsi 97% load density

BLC2 67gns 1896fps @ 62kpsi 96% load density- Maybe use a tuft of Dacron on top of the powder?

IMR 4064 61gns 1722fps @ 56kpsi 100% load density

This is just a computer simulation and not published or tested load data.

When I was loading 500gn cast for my 470NE, I used RL-15, a tuft of Dacron on top to hold everything in place and Fed 215 primers.

[HollandNut]

yeah the first pic I put up is my 750 next to the 462560 , the 750 is a NEI mould , yours looks like a long version of the 462560 . My 750 is 1.8" long ..

[HollandNut]

I have used loads in the neighborhood of what you posted there , be assured when you light it off , you will know ..

[tazman]

I used to have a 458 Win Mag many years ago and thought it was great to torch of the heavy boolit, full power loads. That thing killed on one end and maimed on the other.
I suspect the loads you are talking about would kill on both ends if I were the one shooting it.

Thank you very very much

I've seen H4895 used for Matt's 730 grain in a win mag case 52-60 grains. 60 blew primer. I'll likely start with 52 grains in the Lott case and go up much slower than he did. He had pressure signs at 58 grains but he didn't see it apparently.

Welcome to the forum Nate. As you can probably already tell, there are some really helpful guys on here and it's a great place to learn! I'm not new to casting but I wouldn't say I'm experienced either. I cast for my .45-70 and learned everything I know from this forum. It seems to work ok.

I just came here looking for .458 Lott info too, so in time maybe we can share our findings. I haven't picked up my rifle yet but it's a CZ550 Composite Safari. I'm planning to load it with the Lee 500gr gas checked flat nose as I already have the mould. Time will tell if it works out.

The issue I have is that we've lost a lot of American made powders because of a stupid new hazardous chemical law - a lot of Hodgdon group powders have something in them that means it is now banned. Most of the best powders are gone and I have to find recipes with Vihtavouri, Alliant, Reload Swiss etc. I'm gutted because I really wanted to make some Trail Boss loads but guess what - yeah it's gone!

I've heard similar loads can be made with Tinstar - Viht N32c. But finding data when you guys all use Trail Boss with perfect results is kind of tough. Most of our shooting info is US based and our little island is barely a consideration to big manufacturers of firearm stuff. It's just not a big enough market for them to need to cater for our stupid rules!

For the 730 in the 458 Win mag case, 52 grains of H4895 is a 103% load at 59kpsi, 60 grains is 99,800 psi at 119% compressed charge. So I'm not surprised that it blew a primer.

For the 730 in the 458 Lott case, 52 grains of H4895 is a 81% load at 36kpsi that should give around 1541fps, 60 grains is 55kpsi at 94%

H4895 should be safe to start at 52 grains with the 81% load density.

No IMR powders?

[njc110381]

Some but not all of them.

[Natenator]

Some but not all of them.

Perhaps IMR 3031 or 4895 would be good for your purposes. I can't find viht powders frequently enough for me to trust them. If u have access to accurate powders I forget which but one seems popular for the Lott. Sorry the wasted politics are getting in your way. USA not getting any better. Keep chipping away

[beagle]

Amen to that. I shot some 562560s out of my Number 1 Ruger .458 WM at 2200+. One box was enough. Normally the guys at the range will shoot anything but I had very few takers on this load. Had to finish the box myself. It was accurate but more than I wanted/needed./beagle

I have shot the Lyman 462560 in a Ruger M77 458 Winchester magnum with a full bore load and it is about all you want ahold of out of sandbags from the bench

Remember the load by chance?

I know 4895 is gone, will have to look up 3031.

What do you plan to shoot with those big chunks of lead? Didn't think you guys had big game in Ohio? Black bears and some deer? It'll certainly put them down quick!

[rrob692326]

There was a guy in Alaska who use to sell these, as I bought some from him years ago. I believe they were called Ranger Rick's Tyrannosaurus stompers.

I remember these and Ranger Rick, pretty sure someone at Accurate Reloading Forum was shooting these out of the Lott at 1900 fps, seems like H335 or AA 2230 powder was used.

[HollandNut]

yeah it was Ranger Rick , I got some really heavy 458 , 480 and 500 SW hard casts from him way back .. He had samples he would ship out for a few bucks .. I maybe wrong but IIRC , I checked later and he was out of business , I think he was getting his stuff from someone else and calling them his , or someone else was selling his stuff calling it theirs .. Great boolits and accurate
