Took a while with chronograph to figure out 8 was the best spring tension @ 3500 psi. Average speed 1034 with 257388 slugs. Mine aren’t pure lead. 25:1 with a touch of Oatey Leadfree plumbers silver solder in the mix.

Took out two clay pigeons at 420 and rounds on target at 547.

One of the two clays was taken out by hitting the Berm below it causing it to slide down. Made no adjustment to aim and hit it with my next shot. That’s good stuff at 420 yards.

Due to my lead tin mix my…Read more

Preheating helps. I run two furnaces: a Lee bottom drip that’s there to melt sprues and feed stocks and an RCBS that I pour molds with. I run the RCBS maxed out on its temperature setting, after getting it going I back the Lee down to 7. I use a Lyman ladle to take liquid lead from the Lee to the RCBS. I don’t dross…Read more

Glad you like the mold, and I’m glad I sent some rounds to Jared to get it back into production. I’m not sure bu I think that 257388 was last in production in the 1950s or 60s.

An older couple showed up and were fascinated with my set up. They witnessed me take out two clay pigeons at 420 yards. They tried to help me get out to 840, but no luck there yet. The range has a lot of scrub that eats the missed shots so with no dirt flying there is no way to adjust. I did put five rounds on to…Read more

These should be very close but not exact replicas (see nose profile). I doubt that minor difference will mean much but we’ll see soon. I ordered a four cavity aluminum mold before posting: $75 & $7.50 shipping.

In order to get it into production the tip had to be made flat instead of pointed, but it’s only 0.09 so its pretty darn small and I doubt that in subsonic flight it will make any difference at all to the performance of these rounds. I placed an order tonight for a four cavity aluminum mold and…Read more

Several months ago I sent a few RJ Spitzer rounds I bought from R&L Airgun to Arsenal Molds and asked for them to develop a mold based on those rounds.

No! I don’t have the mold yet, but I do have a picture of rounds that came out of a prototype mold along with this text in an email:

Mondays are good. Hopefully the ground dries up in the next month or so. Long range shooting works better when misses can be seen.

Bring that gas compressor, your rifle and plenty of lead!

I sent 257388 rounds to Arsenal maybe four months ago, so I’d really like to see this get into production.
