New to Big Bore

[OleTomCat]

So I just received a Samyang Dragon Claw .50.

Does anyone know what the nominal bore size is on these cannons?

PA sez .490-.496 roughly. Will Piatt might be able to get you closer for choosing a good slug.

Al Clark is going to send me some of his dropped in .4985, I m looking at some Nielson's 210gr .498 or .501.

I bought some slugs from Nielson Specialty ammo, they shot well so I ordered a mold that was very similar to the ones I bought and after casting some I shot them and they shoot beautifully at 15 yards, going to stretch them out to 50 then 100 yards when the weather breaks....

First Picture is of 175 cast bullets, I inspected 125 measured about 25 random ones, size was between .4985 and .5015, next I took the remaining 50 bullets and weighed them in groups of 10, they averaged 217.9 grains.

Second Picture is 25 of the 50 I weighed.

Third Picture is of the purchased round on the left and cast round on the right.

Went to the indoor range today to sight the scope in on the Dragon Claw .50 at 25 yards....
