if i were to go with sabots over powerbelts, does this require more cleaning e.i between each shot?
I use 2 pellets, go with 3 pellets if you like to punish your self.
Really I've found 2 pellets more than sufficient.
When using sabots you don't have to clean between each shot, I've found that you might have to use a spit patch to clean the bore out, after five shots, to make loading the next shot easier.
I've never used the power belts, but a friend of mine used them, and he said they didn't perform too well on game (deer), the heads broke apart. I use the T/C Cheap Shots, .50 Cal. All-Lead 240grain, Hollow points, they come with the required sabot, and sell for $6.99 a pack of 20 in my area. They are really accurate, inexpensive, and most importantly work well on deer.
I've hunted for years with a Remington 700 in 7mm Mauser, and got into BP hunting about ten years ago, with a T/C Hawken. About 4 years ago, I purchased an in-line T/C Omega, and now have seriously gotten into BP hunting. I also own the H&R/NEF Huntsman & Sidekicks. All are great shooters, and hunting guns.
