I ran this through ChatGPT for you, here are the results. It's AI, so take with a grain of salt... although on the cover it sounds like solid advice. One thing AI does well is gather real world results from around the web, and it appears to have done so here:

For a .410 turkey setup (especially for a 9-year-old), you're basically trying to get
the densest, most consistent 10" patterns at the range you'll actually allow him to shoot—and with .410 that usually means
keeping shots closer and patterning the gun carefully.
Escort .410s are commonly reported as using
Browning Invector (Standard) threads (not Invector-Plus).
But manufacturers/importers change things sometimes, so I'd still
confirm by:
- looking at what your factory choke is marked as, and/or
- matching it by model on a choke maker's fit chart before ordering.
This is one of the most-used benchmark .410 turkey loads and is very consistent. Federal's specs for this load are
3" / 13/16 oz / #9 / ~1100 fps.
It's also commonly listed around
~294 pellets in the payload (pellet count matters a ton in .410).
Also-solid alternatives (if Federal is hard to find):
- Remington Premier TSS .410 (offered in #7 or #9, depending on the SKU).
- Browning TSS Tungsten Turkey .410 (commonly 3" / 13/16 oz / #9 / ~1100 fps).
Carlson's markets their .410 TSS turkey chokes as
optimized for Federal Heavyweight TSS.
On at least one major retailer listing, Carlson's shows .410 TSS constrictions of
0.380 and
0.385 (and offers versions for
Benelli/Beretta Mobil or
Winchester/Browning Invector).
What I'd do for a youth hunter:
- Start with 0.385 (often a great balance—tight, but not "too tight/too picky").
- If your patterns are still not dense enough at your max distance, try 0.380 next.
With a .410, you really want to
pattern on paper and pick a max range based on hits in a 10" circle (and point of impact for his mount). A practical approach:
- Pattern at 20 / 30 / 40 yards from a steady rest.
- Use a turkey head/neck target.
- Pick the farthest distance where you're getting consistently lethal head/neck hits, then back it off 5 yards for real hunting.
For a 9-year-old, I'd
strongly consider building the hunt around
inside 25–35 yards unless your patterning proves otherwise.
- Federal Heavyweight TSS .410, 3", 13/16 oz, #9
- Carlson's TSS Turkey choke in the correct thread for your Escort, start at 0.385
If you tell me
the exact Escort model (and ideally what the factory choke is stamped) and whether you'll be hunting
tight woods vs fields, I can narrow this down even more (including whether it's smarter to start at 0.380 vs 0.385).
