Texan .457 w/ .454 Slugs?

Jump to latest Follow Reply
Hunter Supply provides so many 45# to fit your barrel but for the most part if you have a stock Texan that is fairly new then I would advise staying with the .457 unless you are having some issues with accuracy 

The .454 will not engage the lands as deeply and this will lower your drag and perhaps strip the bullet at higher velocities but if your shooting at lower pressure tune you might be okay

Thank you!

I only see 170gr in .457 on Hunters Supply. 



Edit: oh nevermind, I see them.

For anyone reading this in the future...

I contacted Hunter's Supply to ask about use of the .454 slugs in the .457

They said that they work fine but

.454s at 100 yards = 2" CTC

.457s at 100 yards = 1" CTC



So why choose a .454?

Hunter's Supply was kind enough to include the BC data for their slugs. For some of the lighter slugs (250gr range) .454s seem to have considerably better BC. So I bought some and will try it out. 1" or 2" is the same to me at 100 yards, I'd rather have a higher BC for better downrange power and flatter trajectory.

Interesting, I look forward to seeing your results. I personally use .454 NSA 220 DPHP's in my standard Texan with a 3000 PSI fill, I can't shoot 100 yards but get under .5" groups at 75 yards and get 4 shots with the 5th being a little low, maybe half a mildot on my scope, so I'm 100% with you on liking the flatter trajectory and higher shot count. I've taken 5 deer with these slugs and not one has gone more than 50 yards, however I rarely get pass through just due to the lightness and the massive expansion of the HP, just something to also keep in mind if you are going to hunt large game with a lighter slug. Again, look forward to seeing how the .454s do, good luck!

That's excellent first-hand experience, thank you for sharing. 0.5" at 75 yards is more then enough accuracy for me -- I hope I get similar results.

I only got my Texan SS a few days ago so no shots yet. Next time I get the chance to go to the range I'll try them all out and share my results.

If the smaller diameter lead doesn't work out, you could bake a coat or two of powder coating on them as a cheap and easy experiment. This should bring the diameter up a few thousandths (per coating) as well as seal the projectile in the barrel's grooves, tightening up the group size.

I had a similar idea though I was thinking of trying Lee Precision's Bullet Lube -- same thing you use when casting your own bullets.

Though I'm wondering if that will leave some residue in my barrel.

I stay away from goopy bullet lubing products, or anything else that leaves residue, including dried films that may cake up over time. I found that a wet lube of silicone oil works great and keeps my bores accurate, lead-free and always shiny. I use a pellet container with a healthy dose of silicone oil sprayed on the foam to lube them right before loading.

I gave the .454s a try in my .457 Texan today. At 50 yds they all stayed in a 2" group. I will be working with these to see what they do at 100yds. To be honest the .454s shoot better than the .457s I am casting myself. Only got to play a little while, I have many more projectiles to try. The group was with 196 grain NSA hollowpoints. I didn't use any type of lube to help take up slack.

I have a .454 mold that makes bullets I like. They shot good in my my DAQ.458. But it bothered me that I couldn’t get them at .457/.458. So as suggested above I powder coated them and now I’m getting.457 -.4575. Way better. They are accurate and fly a little faster now.
