20GA Rem Sluggers

[336A]

I picked up some of these just the other day for my H&R pardner 20GA. One of the slugs was sacraficed in the name of science. A lot of people seem to think that slugs in general are under sized. Years ago this used to be the case, anymore though they are full bore diameter. Once I got the slug out of the hull I pulled out the calipers. The slug measured .614, while this is not the full bore of .615 for the 20GA the slug lodged just forward of the Pardners chamber when I did a drop test. So much for todays slugs being undersized Next the slug was weighed, Rem claims 5/8 OZ which converts to 273gr. The RCBS scale said otherwise, the slug came in at 293gr.

Now the thing that perplexes me is these slugs are packed full of Grex buffering behind the slug This is the only slug that I've encountered that uses buffer material. Can anyone speculate as to why they would use buffer and no one else does? Finally I also cut open a Federal Truball slug, it mic'd right at .729 and came in at a full ounce (437.5gr). So there you have it two slugs (of recent production) in the most popular gauges and not one was undersized. As I stated in another post all of the ammo companies fixed the issue of under sized slugs some years ago. The issue of under sized slugs is a thing of the past.

It has been my experiance that if you try different slugs most of the time you can find somethig that shoots acceptable I start with remington on more open choked guns and winchester on tighter choked guns and go from there till I find something suitable only guns I have not found something that shot ok is a m-6 springfield and a H&R 10 ga only one slug made for 10 ga

Remington's marketing people must figure saying "5/8 oz" is close enough. They're only off by 7% or so.

I assume there was some kind of over-powder wad or powder seal disk. Maybe the buffer was in there to keep that disk from hitting the base of slug. In my own handloads I've seen that happen and it will really deform the base of the slug - causing poor accuracy.

Choke -vs- Slug diameter?

In light of the measurements given. would ANY choke be affevted?
I have read that it isn't good to shoot Slugs through any choked barrel.
Please help by explaining this?
Thanks,

ZVP, Rifled slugs can safely be fired through any choke from IC through full. They should not be fired from any choke tighter than full i.e. the super tight Turkey choke tubes. Often times Cylinder bore (no choke) or IC provide the best accuracy, though this is not always the case. Sometimes you may find a shotgun that shoots slugs better with a modified choke than IC. The rifeling is on the slug so that the soft lead slug can be swaged down as it passes through the guns choke. This also explained here under the FAQ section http://www.brennekeusa.com/cms/h_home.html

Kernel, there was fiber card wads under the grex buffering, and a plastic over powder wad under those. I know the older version of the Winchester Super X only used fiber wads under the 12GA slug. They have since moved to a plastic wad. I do believe that they still use fiber wads though on they're 20GA Super X slugs.

I took apart a Remington Buck Hammer sabot slug (now discontinued). Between the slug and the over-powder seal-disk there was a little soft rubber disk, about the size of a M&M. I assume it was there to act as a shock absorber.
