Bullet Jump

Jump to latest Follow Reply
As far as pellets go, it doesn't seem to matter. I prefer a longer leade and have seen the same laser accuracy with a .1" or a 1." leade on LW barrels. Look at the early Smooth Twist barrels, they only had rifling at the last couple inches of the barrel and are very accurate. I also have single shot guns that have no leade at all and are still accurate.

With the variables and poor aerodynamics of pellets, I don't think we'll see the minute differences in accuracy that a powder burner shows.

I'm still experimenting with the leade length on slugs.

Thanks the info. I had a feeling that for pellets it wouldn't be a life changing thing. I am familiar with the FX barrels in topic not experience with a smooth bore and rifling at the end. With that though FX has separate slug barrels which i would assume would have rifling all the way down. I guess i am more interested in if bullet jump for slugs will matter. I would like to experiment with my .25 Benjamin armada and see. But the only slugs i can seem to find and too long and you have to push them into the rifling when chamber-ing them. The accuracy as a result was poor i believe for that reason and because the slugs may need to be sized.

I've done a lot of reloading for powder burners. They'er different. Just as "cosmic" said minimal. 

Powder burners have to jump. It's the nature of the cartridge design. Not so for PCP's. 

I feel that airgun slugs need to "seat" lightly into the leade. Not a hard force fit though. That usually causes poor accuracy. 

A jump could cause possible blow by and a misaligned slug. 

My two guns I shoot slugs out of "seat" the slug. Just my experience.
