Lanes Tubes


Shoot and Hunt Safe

Lane

Thanks,bought 12 of them

I am a fan of the “Lanes Tubes”.
A long one with a pre measured powder charge, taped to a small one with 1 bullet and two primers.
Three of these in a pocket, and a few more in the pack.
Fast re-load after the first shot.

"Fast" is not a term I'd use for reloading a front stuffer! Even with Lanes' tubes! But your method is quicker.

bought some also, they are great for organization. I put powder premeasured and several slugs in a few. they work great
