Bought a new Ruger 458 LOTT on Sunday and would appreciate any suggestions.

85 grains of hodgdon4895, hornady brass, 405gr remington soft point.

cheap plinking load. i get 2550 fps avg out of my cz550. shoots 2" at 100 yds out of my rifle

Thanks that was a bullet I was looking at for mass volume shooting due to the cost.

In my CZ 550 Lott , 85 gr AAC 2230 with a fed 215 primer , Pushing 400 gr Moly tumbled 400 gr Kodiak Bonded Core bullets @ 2555 fps avg @ 18 feet , extreem spread was 11 fps .,

It will go faster , but I don,t think I need it to ...
Next I,m going to try 81 gr H 4895 with a moly tumbled 450 X ... Hope to get 2450 fps with it ... I.ll start lower and work up ... 2450 is just under 6K ft lbs .. I think that is enough ...

Here's a few that I use in my RSM:

(reduce by 10% and work up, of course)

Barnes Bullets website,and the "search function" or google it. I found tons of data that way. Even found the original "Handloader" (or was it Rifle? ) article.
