.30 and .35 slug recommendations

[JamesW1]

Looking for slug recommendations for AEA HP Max in .35 and Vulcan3 in .30.

Also, how do you folks feel about "slugging" the barrel for sizing the slugs? If you are pro-slugging -- what slug would be a good initial size for slugging a barrel in .30 or .35?

Sure would appreciate any info on casting good slugs too.

Thanks.

For measuring groove diameter I usually just bump the slugs up with a small hammer until they are large enough to fill the bore. If your sizing your slugs by pushing a slightly oversized slug through the barrel, I think that could be very time consuming and possibly damage the slug base.

I do not have a .30 but for my Bulldog I cast the 152 NOE hp and the accuratemokds 122 grain bullet. I suspect both would be too long for your magazine.

One thing that will make life simpler for casting and sizing is to custom order a mold to a specific diameter, Arsenal is the only mold producer I know if that will do that. I usually specify a mold to drop at groove diameter with pure lead. If it ends up being slightly undersized, I add a bit of tin to get the exact groove diameter. The more you have to size a bullet down, the more prone that bullet is to damage..

Good Luck,

Roachcreek

for your vulcan,
the jsb knockout's in .30 does very well from my Uragan-1
i've tried many others and none compare with them.

For an initial visual reference, use whatever pellets that you have on hand to push them through first. This will give you an idea of the amount of force needed to push through the barrel and a visual reference (with a magnifying glass) to the witness marks on the skirts. Then you can push a swaged slug through to get a comparative idea there as well. (NSA's swaged slugs are manufactured with a good repeatable reference to diameter and as such will give a good initial observation reference. They can be bought in inexpensive sample packs in different size diameters and weight for testing.)

Both the pellet and slug should have some amount of witness markings from the barrel. Pellets will almost always have both land and groove marks because of their larger head and skirt diameter, whereas the slug may only have the lands marking the side.

Looking at them both through a magnifying glass, you compare the corners of the lands and grooves depths as well as possible witness marks from the bore (maximum bore diameter). Even without precision measuring micrometers or calipers, simply doing the visual observation test that will usually show if an even larger size swaged slug than commonly sold may be needed for the particular barrel.
