Hello Guys, I have a question: maybe someone has had some experience with this, or has some wise words to share?
When using the Lyman 525 - I got used to putting a Plastic disk [Or two] beneath the slug to raise the slug a bit and to prevent wad blowing into the cavity. It seems it has worked.
Now with the Lee Key Drive Slug [I just got a mold for it!] would using such a plastic disk [Or two] adversely affect performance? I seem to need to put the disks to raise the slug to enable it fit well in the Wad/ shotcup, and to enable a good height for the roll-crimping that I do.
I know that the 'key' enables the wad to positively engage the slug, while engaging the rifling to impart good spin [In a rifled barrel] and I know also that the 7/8 slug [Which is what I got.] is definitely nose-heavy and should perform well in a smoothbore too.
Remember - I am simply replacing birdshot with slugs. And for these now: I am also changing the Wads to WAA12-type wad [Bought 500 off Amazon on my last US Trip... It made for very good packaging material in my suitcases!]
I am using: in the shotcup:
* 1 pc Felt Disk
* Then 1 Thicker Plastic Disk
* Then a VERY Light Plastic Disk
* Then the Slug.
[Some shells I used the over-shot disk, and some I roll-crimped without the over-shot disk.]
So, will using the plastic disk[s] disturb this positive engagement of the slug? Or will the wad engage the disk via friction, which will in turn engage the 'key' of the slug, and the petals also will press into the slug sides while compressing into the rifling lands and grooves to impart spin stabilisation?
See Disks in picture below. Thicker ones from Bottle caps, thinner ones from Window blind material: more brittle.
