I can do up to 6 seconds I think, but then the charges are low, and like I say I'm looking to one shoot the critters. I have another bow that is 4 seconds I found, I've been using that but I seem to be charging it a lot. I figure I can reserve that one for bigger critters I can 2 shoot and use this new one with as many charges as possible, for my one shot kills on deer, elk, goats, wolves etc. for petty gems. I have a lot of iron daggers made I'm making them to up my smithing, but then I need petty gems to enchant them to raise their value before selling them. Lather rinse repeat. It's how I'm buying and stashing the Grand Soul Gems for when my enchanting is better. But I'm burning this one to make a petty soulcatcher. *grin*
Just seems 1 second isn't enough even with a 1 hit.
But yeah, I think I'll go with 1 second to have 1k charges on the thing. Thanks for the quick response.
