I made crude bump dies back when I was shooting BPCRS. Essentially, you find a drill bushing the size you want and a rod of similar size. The slug goes in the bushing and the rod is the bump. Whack it with a hammer (on an appropriate surface). The slug will conform to the drill bushing size.
No, it isn't perfect. If your slug has a specific nose profile, you can cast the profile in the bottom of the drill bushing by using epoxy (JB Weld) and a release agent (like Vaseline or silicone lube). I had access to "dental stone", which is a water mixed powder. Sets up very hard and doesn't shrink. It helped me decide on whether to have a custom mold made or not (I did, it didn't help my scores). Obduration in cast bullets happens so quickly in a PB that perfect fit isn't really necessary. Different with PCPs.
If you can't find the exact drill bushing size, you can take the nearest smaller size and hone it to size with emery paper (or wet/dry sandpaper). I looked at McMaster Carr and they carry 0.302" drill bushings. They also probably carry hardened dowel pins at that size. Often you can get them in 1/2 thou increments.
Edit: They have "Core Pins" in both 0.302" and 0.303".

Doing a little product testing for a fellow air gunner… still waiting on my picatinny to arca adapter to come in the mail but so far I’m really impressed.

Okay y’all… varminintknockers .303 slugs are definitely good out of the EQ… I’m not done with the testing but in at 119fpe with the 62gr slugs and still getting a full mag a fill.
Most importantly the accuracy is on point!

Knurling to ‘increase diameter’ has been done with good success by several. It can be done ( not 100% consistently ) with a file or with a dedicated machine/fixture.
The pellets are likely grabbing the rifling fine due to the skirt blowing out and engaging. The fact that they do not spiral is not necessarily evidence that they are not grabbing the rifling.
Good luck with your endeavors,
Dave

These Varmintknockers 62gr knurled .303 and .306 slugs are doing pretty well. The only difference is that the .306s are doing about 10fps less than the .303s.
I have more to test this upcoming week from NSA and BARS. Both in .303 & .304. none are knurled.
This video was taken about an hour ago…
