Texan 457 light slugs

Just bought a Texan 457 with hawke scope setup. It's my first pcp airgun and I'm learning a lot already and have to say I'm hooked. Now that I have it and have shot it, it wouldn't have been my first choice but I still like it. I probably will never hunt with it and know I won't be taking it to the range without a tethered setup. Since I'll mostly be shooting it in the back yard at paper or reactive targets, I'm looking at lighter weight more economical slugs. Anyone have any recommendations of anything that has been particularly effective for them?
 
I’m almost in the same boat. A friend of mine sold me a Texan SS 457 for dirt cheap as he received it on a barter and isn’t interested in airguns. So that started my whole venture into this hobby. Anyway, the previous owner clearly liked the lighter Seneca 45 200g slugs because out of the boxes of ammo I was given only 1 of them was 350g.

They have been fine on my particular model but it’s old, it has the TX1 valve and aluminum bottle. FPS is around 940fps and the groups at 50 yards are fine for me, but I am mainly killing feral hogs and coyotes on my property vs. putting the slug in the same hole on repeat.

I will say this, slugs are expensive, I was actually surprised (ignorance) that a box of 50 for .45 cal slugs is on par or just as expensive as my powder burner ammo. So now I’m looking at learning how to cast my own slugs. Best of luck!
 
Casting is the cheapest way to go I've been casting bullets for 30 years. I have a Texan and a XP Ranger both in 45 I have a Lyman mold that drops a 180gr hp that shoots good to 75 yards, I have shot 454 diameter in the Texan with good luck and that's what the Ranger likes 454.
The 2nd pic 180gr hp, the 1st picture is a 280gr hp I cast and powder coated. For shooting paper and plinking you could also shoot muzzleloader roundballs their alot cheaper.
