Hi POP! I have been playing with my new toy the last month. Trying to developed a good load for moose and boar using the 350gr Speer.This bullet should be adequate for moose http://ulfhere.freeyellow.com/ballistics/methods.html#large_bore The maximum load suggested from Norma (since I live in Sweden  ) was 73,9gr of Normas N200 wich schould give approximate 2590ft/s.I have loaded up to 73,5gr wich gave 2605ft/s in my rifle (25" barrel) with no pressure sign. The load I will use on moose next year will probably be 73,0gr of N200 wich gave 2570ft/s and seems to be accurate. This load will let me aim dead on with 6cm high on 100m and -5cm at 200m wich anyway are the farthest i dare to shoot PerN | |||

Pop, I have had 3 Model 70s and they all did very well with 70 grains of 3031 with 400 Speer seated to the rear cannelure. Velocity was right on 2100 f/s. Also 70 grains of 4064 was real accurate and does 2000 f/s. Killing power on roos and goats is incredible. I also used Varget and another Australian powder which is about like 3031 and Hodgdon probably sell as H3031 Extreme. You would need to check that. Again, 70 grains with both powders. The 500 Hornady with the same loads also shot very nicely and with the 3031s velocity was just over 2000 in the 22 inch Model 70s. I had a Ruger for a only a very brief time and it also seemed OK with these loads. I shot it with the forend removed and the barrel on the sandbag. The main problem area with 458s is lighter loads with 300 grainers. 458s have very long freebore and this in combination with the light bullet and very small case capacity for the bore size can produce hangfires. I think a 458 Lott basically leaves the 458 throat and therefore of course reduces the freebore by .3". So a 458 Lott might actually be more flexible with reduced loads and would be super easy to do in the Ruger. I have never owned a 458 Lott so I am having an "educated" guess on the freebore situation. Mike | |||

POP, I don't know about that 350 Gr Speer...I would use the Hornady bullet. I shot a moose quartering away with it and it never reached the vitals. Just tore up the stomach (he turned at 30 yds and it downed him thru chest cavity, but penetration was minimal) PS My brother's pretty excited about your 450 Marlin. His intro to Big Bores..... | |||

Hi 4x4! Could you be a little more detailed on rifle, bullet (was it realy the 350grhot-core and not the softer 400gr), speed... When you say you would prefer the Hornady is this the 350gr or 500gr? Since I do not have any experience from how this bullet's will perform in game and the Speer seems to tuffer in most test I am a bit suprised of your results? PerN | |||

My #1 loves the big Hornady 500 gr. sp's. You can load them very long as the Ruger has a very long throat. I have good luck with IMR4064 and 4198. I can get 2300fps with no pressure signs. Recoil is stout! I picked up some 400gr Remington .45-70 bullets at a show and they shot well at 2200 fps. I have not had much luck with the lighter bullets. C.G.B. | |||

PerN, It was a Ruger #1 45-70 with a custom long throat using the 350 gr Speer flatpoint at about 2300 fps. I don't know why this happened. The Speer manual (in the 458 Mag section says this a good bullet for the big bears. I have my doubts. Other people I've talked to have had success with Hornady's 350 Gr RN on Eland (1500lbs quartering on). The Interlock is the good feature of this bullet. My brother's going to use this in a 450 Marlin on moose this fall and I'm going to use 400 gr Swift A-frames at around 2250 fps. [This message has been edited by old4x4 (edited 01-11-2002).] | |||

PerN, You will really love these bullets. I use Honardy 300 gr HP, 350 gr and 500 gr for my .458 loads. And I'm planning to use only 350 gr and 500 gr for my .458 Lott loads. All of these 3 Honardy bullets have a good penetration but for big game hunting forget the 300 gr HP. ------------------ | |||

If you are looking for a bullet that will hold up at long range and really flatten the trajectory of the 458, try the 400 gr. Barnes X. My M77 458 will put them under an inch all day long and the high BC of those little pills really flatten things out quite nicely. If looking for a high speed "varmint" load, try the 300 gr. X. You can really push that little pill. For impressively long loads, the Barnes 500 gr. X and the 600 gr. original work real well also. In the No. 1 you won't be constrained by a magazine like I am so you can seat those long 600 gr. and 500 gr. X out there and still have room for powder without too much compression. | |||

I am hesitant to post any loads as they are above any listed. I am only seating the bullets about .25" and am still way short of hitting the lands. I don't know if this long throat is common to all #1's or just mine. Start with the listed loads for 4064 and work up from there. IMR 4064 has turned in the best accuracy in my rifle. I will dig through my records and see what my actual oal was and post that much. Currently my stock has developed a crack through the pistol grip so I have not shot the beast much lately.

Reduced loads I finally made some cast bullets of my own. I used Lee 450gr mold.  This bullet was loaded with 15gr of RedDot In Winchestere brass with CCILR primers to a velocity of 1100fp/s the. The precison with 5 shots at 75yard was ~3" PerN | |||

Pop, A 378 Weatherby,now a 458 Winchester?Man,you're worse than I am. I have recived good accuracy from my 458 with handloads using the Hornady 350 grain RN and with some older Winchester 510 grain factory ammo.The 350s wouldn't feed through my Browning Safari Grade,so I just shot it as a single shot.I have a bunch of handloads topped with Hornady 500 grain RNs that I will try during my next trip to the range.I am going to try Reloader 7 and also IMR-4064.At 2050-2150 FPS from my little 8 3/4 pound rifle,they should properly kick the snot out of me from the bench. I am currently trying to trade for a pair of Ruger #1s in 375 and 458.Want the 458 just to shoot the Hornady 350 grain RN at 2500 FPS or so.IMO,that would make the perfect deer/black bear/elk load for the 458,as it would pack plenty of wallop and and shoot flat enough for shots out to 250 yards or so.
