Accurate Powder has a feature where you can submit a request for data. I have done it several times; they were very helpful each time. | |||

while not a 458 lott i use 35 grains in a 470 with a 500 gr cast bullet. I believe the velocity is in the 12-1500 FPS range. i think your lott would be similar | |||

tank, just send Accurate Powder your request, for bullet and velocity wanted. They are very helpful. Best to get it from the "horse's mouth". Keith IGNORE YOUR RIGHTS AND THEY'LL GO AWAY!!! ------------------------------------ We Band of Bubbas & STC Hunting Club, The Whomper Club | |||

I sent them an email and submitted their online data request form 6 days ago and no response yet. How long has it taken them to respond when you have requested info in the past ? | |||

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.
