Some advice and wisdom please.

Thanks everyone for the information. I'm going to start by using only these spitfire TMZ bullets because I have 48. I'm going to start at 80 grains and go up from there until I figure out the sweet spot. I'm going to try the cheddite primers as I've heard they are hot and should give reliable ignition. The "spot on" app with that scope gives you lots of virtual data to work with. I intend to shoot cold clean barrel for each shot and use a chrony....Range report will follow.

You also need to wait at least 15min between shots. Heat and plastic sabot equal mayhem! I shoot smokeless out of my savage but bh209 is very similar in the fact that you need a tight fitting sabot. Most on the market are too slick. Thats great for easy loading but not for tight groups and consistent ignition. I would get some MMP sabots and shoot bullets that the savage guys are using.

Because BH 209 is a smokeless deriv it needs to work. It burns like smokeless so it needs the whole cycle of heat makes pressure makes heat makes pressure repeat. Doesn't go pop like BP or it's subs so yes things gotta be snug. Powerbelts and such will eventually run into a squib load

The guys in my group have the impact guns. I have seen them work very well during our controlled hunt. Post some pics of your groups once you get it dialed in...

Have a look at my range report thread. I'm happy with the gun.
