We will have quantities ready to ship soon.

The ShortRangeTarget slug is a pure lead 40gr .2185" design that Is made to excel at 50y BR from airgun barrels.

The slug exhibits a G1 BC of between .140 and .150 at 50y using velocities of 750-900 fps from an appropriate barrel. Twist rates from 1:15 to 1:17.7 are needed depending on elevation. It tracks extremely predictably in the wind and this will be the slug Team USA will be using for the 50m Unlimited class at the World Benchrest championships in Finland this year.

Cost will be 40$ per 200 and 12.50 flat rate shipping inside the USA for up to 600 at a time.

To order....Please send email to [email protected]

Thanks

Perhaps do you mean - a semi wadcutter, swept curvy boat tail, flat end tip, "target slug" :p;)that shoots better than anything else on the market.
:unsure:

Darn, Mike I just bought a couple years supply of Altaros 32.3's so now I have to rethink my strategy, hmm do I go for more precision or more BC, that's a tough one.

The Thomas slugs are formed, tumbled, then final swaged.

If you swage a rebated boat tail in one pressing...you trap air in the die. When the air escapes...and it will...it tears a section of the shoulder. It may look 100% intact, but it will crumble off with very little effort. The best situation is that the small piece of lead that is separate from the main body falls off prior to shooting. The missing piece doesn't cause huge problems, usually. If the piece comes off when chambering and gets between the slug and the barrel its usually a massive flier.

After the first forming press, the slugs are tumbled so all the pieces are forced to fall off. On the final pressing there is no air trapped because the slug is already fully formed....but just a little bigger than final. The slug shoulders will now be solid and if you throw the final pressed slugs in the tumbler again you will not find any of the crescent moon slivers that are prolific on the first tumble.

You can take 2 seperate pieces of lead wire and press them into a single slug which will look flawless and even stay together with mild force. It will separate with enough pressure, though.

The slug on the left is 2 pieces.

The little slivers in the other pic are the shoulders that appear attached but fall off after tumbling.

There are things you can do to minimize the air problem...but it's not 100%. Tumbling and repressing are a 100% solution.

For the air pockets, I repress 3 times with rotating. Seems to work and the shoulders don't have any burs.

when i first opened this thread , My first impression was "rip off " prices . Then i read the whole thread and see that it was not price gouging . The extra care and involved steps and handling (time spent) deserve the asking price .
Just like the guns he makes , worth every penny .

Mike, how do you tumble the slugs? Just a bunch of slugs together in the tumbler or do you use media? I have been making boat tail slugs with my corbin press and have found this issue. I found with a straight cut on the wire it helps. Also I found if you start to form with a flat base die it helps also. But it didn't solve the problem completely. I will have to try tumbling.
