I have been really itching for a Ruger #1 in 458 Lott lately so I bought one.

Can you share some of your full power loads and some 'plinking" or should I say reduced loads?

BTW just for laughs what can you launch a 300 gr Barnes X at from this beast?

I haven't loaded up any full power loads yet in mine but I can tell that 50 grains of AA 5744 with a 500 gr. cast bullets are very mild to shoot and hit really close to the regulated sights on my rifle. Below is some info I request from Accurate Arms for data using a couple of their powders.

"Unfortunately we do not have any specific lab tested data on this caliber. (See notes 1.1 and 2.1 below).

However, we can provide you with some guideline, based on calculations and information from other sources.

Bullet weight: 400grains.

Start load: 71.0grains (2300 – 2400 ft/p/sec)

Maximum load: 79.0 grains (2450 – 2550 ft/p/sec) Max pressure!!.

Bullet weight: 500grains.

Start load: 68.0grains (2100 – 2200 ft/p/sec)

Maximum load: 75.0 grains (2250 - 2350ft/p/sec) Max pressure!!.

NOTE:

It’ important to note that:

Whenever Western powders Inc do not test, and have actual data, on a particular caliber or caliber/bullet combination, we may in some cases provide some guideline. This information will be based on various procedures and calculations, or from other very reliable sources.

1. SAFETY is our prime concern therefore:

1.1. The loading data is conservative, especially regarding the minimum or start load to ensure a safe baseline to work from.

1.2. The safety margin built into the start load might be more than the customary 10%.

2. We strongly recommend.

2.1. To always start at the recommended minimum “START†load.

2.2. If at all possible, measure the velocity.

2.3. Contact us again with the velocity data, so that we can verify, and correlate with our calculated/estimated data. The data should also be compared, with the typical velocity levels accepted in the industry, for that particular caliber-bullet weight combination.

This is interesting for this Powder: Accurate -- 5744. increasing the load 16 grains gives no increase in velocity just max pressure.
I would like to try that load over a chronograph when it warms up and see for my self. I think it just shows that that isn't the best powder for that load. You might look at there 458 win mag datta to they list some outher powders that might work.

Bill,

I would have to guess that the max pressure 5744 load velocity data is a misprint.

I agree, I think it's a misprint.

Try 87 grs of WW760 and a 500 gr woodleigh. That is a good starting load.Crimp heavily and use a fed 215.-Rob

The Barnes # 3 manuel shows 300 gr. X H 4198 80-85 gr. max.max velocity 2850 fps.......You can see the results of a simular load but in 416 rem mag in my avatar. If you hunt edible animals with your 458 Lott you will of necessity learn to be a good shot...A good genral purpose play load is a 350 Speer ,Hordady or Berry,s plated with 82 gr H 4895..... The 300 gr X bullet would work well on elk out to 400 yrds......according to the barnes book if you sight it in to be 1 1/2 " high @ 100 yrds it is only about 11 " low @ 300 yrds ,,where as a 180 gr XFB 308 bullet @ 2800 fps muzzel velocity , . If sighted 1 1/2 " high at 100 yrds will be around 8" low @ 300 yrds.......3 inches isn,t much different....But I bet the elk would act different.......Have fun ..

Here is my plinking load.

405gr Rem SP
68.0gr IMR-4895
OAL = 3.53"
mv - 2112fps/24" barrel

Shoots great

Keith

ps: put a GOOD recoil pad on that #1.

Plinking load is 70gn RL7 with 350gn Hornady RN
Hunting load is 70gn RL7 with 500 gn SP or solid.
Job done.

If you can stand "full power" loads for the Lott, in your #1 you're a better man the me. I have a 12 lb. custom #1 in .45-120 and 86 gr. of WW785 and a 500 gr. Hornady really get your attention.

“I would have to guess that the max pressure 5744 load velocity data is a misprint.â€
I was thinking that but you never know and I didn’t want to come right ought and say BS.

Pop, me thinks you're a gluten for punishment.

About the verstility of .458 lott with regard to reloading, There is an interesting paper by Don Heath in the volume 6 ,2006, of "African Hunter"

You thinx correctly!

POP,

I now use just two loads for my 458 Lott, one 70gr RL-7 w/ a Rem 405 for ground squirrels and 82-83grs 4320 (will have to check my notes...) under a Hornady 500gr for busting rocks. The RL-7/Rem 405 load is pretty economical, hydraulics varmints and gives me a good "big bore" experience at probably 85-90% the recoil of the 500 gr full loads (and it does a much better job on small critters!).

The 458 Lott round is very versatile and I love it. Although you didn't ask for advice on your rifle I will offer it anyway Put on a good pad. I used a slip on Limbsaver on my #1 Lott to good effect, but a permanent one is nicer looking. This is mandatory as the stock "butt pad" is a cruel joke. I shot my bone stock #1 (iron sights, out of the box) Lott with factory 500gr loads and remember it! Cool as a macho "stunt gun" but really the recoil factor was above the caliber, if that makes sense. My Limbsaver tamed it down to comfortable.

After my first "stock" shooting I also polished the trigger face and the tang safety with emory cloth (with good use of masking tape to avoid scratches on the stock and action)...to obviously smooth the surfaces of both. If you think this is nuts you may not have fired a stock #1 Lott or have tougher skin than I. After 15 rounds my trigger finger and thumb were abraded and countermeasures were called for.

Again congrats on your Lott purchase
The #1 Lott is a great rifle and will give provide a LOTT of fun for the dollars.

How much more powder can be added to loading data for the 458 WM for use in the Lott ? The data from Accurate Arms I posted above really doesn't make a lot of sense. If you look at their suggested max load for a 400 gr bullet using 2200 powder, they show 79 grains. They show the same amount of the same powder as max for the 458 WM using a 400 grain bullet in their loading data. I have a long throated chambered Lott and I'm thinking that 10% more powder than what the win mag calls for should be okay. What do you guys think ?

Tank ,, With the 400 gr bullet the Barnes manuel shows max loads as ////H 335 84.5 gr. vel.2474....///// H 4895 ,,,85 gr. ,, 2550 fps....////..The Hodgdon web site has lots of loading data for the Win mag.. max 458 win mag loads tend to be starting 458 Lott loads in the Barnes book...So far I like H4895 in my Lott,, as it is my fav. powder in my 416 Rem mag... //////////////////Always reduce max powder charges for the cartridges by 5 grains or so and work up carefully if you so desire... The nice thing about the Lott is it does well at win mag velocities....
