Slug Barrel for the BT65 .30

[Bwalton]

I understand, but what I do is use one barrel for one projectile, In this  Hatsan .30cal I will not use anything other then the JSB 44.75gr pellets ever. So I will buy another barrel to get to play around with cast pellets. Just me, I do not like using a vast amount of various pellets and stuff inside a barrel that I hunt with that is consistent. Also I do not have the accurate details of the LW .30cal slug barrel as it is not listed on the site. Could very well be a .308 do not know until he gets back to me.

Since I began casting the barrel sizes are what worries me.  I'm still a complete noob at casting.  There's the .300 size barrel for most pellets, .308 for US firearms and .303 for UK.  Having tried several bullets in my .357 cal I know sometimes what seems like a great bullet on paper do not always work well in a particular barrel.  One reason I'm leaning towards just getting a heavy pellet mold for the 30 cal for better ballistics.

".303 cal" is actually 0.311" groove diameter, and the pellets that Daystate use are the same 0.300" head diameter as those used by FX, and both are made by JSB.... I have no idea what the actual groove diameter of a Daystate barrel is, but I have heard that using the ".303" designation was only to take advantage of the popularity of the name in England....

I meant the UK powder burners barrel.

Yup, .303 cal measures 0.311-0.312" groove diameter.... https://en.wikipedia.org/wiki/.303_British

All the more reason to stick with heavy pellets, the 30 cal designation is just so confusing when it comes to choosing a size for a mold.

[Bwalton]

The problem with heavy pellets is that JSB changes their shape...

What makes the LW .30 a slug barrel, twist or diameter to that of .308 PB barrels or both? A good reason I cam think of for a manufacturer to create/replicate something is to increase/improve its offerings to its customers or possibly expand upon them. Especially if they will do the work, however no one has mentioned if this is a drop in barrel.  If not, and I need machining, I can certainly see why one may choose a more proven product with equal required work for completion. Seems her would ne more options with the .308 PB barrel size. Still havent read much about BBT, but also have not seen a .30 airgun that has enough power to do it justice other than Hyabusa :-)

Not a drop in barrel, Woody at LW could answer those questions about specs

"Not a drop in barrel,.."

Thanks, thats what I needed!

[Mod90]

Baxter, is that a blank or drop in barrel? Is it the twist that is making it a slug barrel or the size, ie is it a .308 or the same as the other barrel with a different twist?

Well besides the difference in bore size starters an AG barrel for shooting pellets will almost always be choked, & a slug barrel will not be choked. For shooting diabolo pellets that choke helps to improve accuracy. But for shooting solid slugs that same choke will hinder accuracy.

That too, thanks Ricky!

And to Knife's point, for a person like me, using a .308 would provide more opportunity in ammo selection because I would need to buy off the shelf initially (maybe for ever if I rather spend time shooting vs casting, if limited).
