New Idaho Muzzleloader Load Development?

[timcorcoran]

Hey Folks,

Now that Idaho's muzzleloader regs have changed, what new loads are you using?

Here are the updated 2024 Idaho Muzzleloader regulations (from https://idfg.idaho.gov/hunt/weapons/muzzleloader )

LEGAL IN MUZZLELOADER-ONLY SEASONS

Any person hunting in a muzzleloader only season, including controlled hunts, must have in their possession a license with a muzzleloader permit validation. During a muzzleloader-only season, it is illegal to pursue or kill a big game animal with any firearm, muzzleloading pistol, or weapon other than a muzzleloading rifle or musket. In addition, the muzzleloading rifle or musket must be:

• Capable of being loaded only from the muzzle.
• Equipped with only open or peep sights. Scopes and any electronics are prohibited, except hunters with a visual disability may apply for a Reasonable Modification Permit to use non - magnifying or up to 4x power scopes. Application available at Fish and Game regional offices, see page 4.
• Loaded only with loose black powder, loose Pyrodex, or other loose synthetic black powder. Pelletized powders are prohibited. • Equipped with a single or double barrel.
• Loaded with a projectile that is within .010 inch of the bore diameter. Sabots are prohibited.
• Loaded with a patched round ball or conical metal or metal alloy projectile with the exception of allowance of accuracy tips and pressure bases.
• Equipped only with a flint, percussion cap or musket cap. 209 primers are prohibited.
• Equipped with an ignition system in which any portion of the cap is exposed when the weapon is cocked and ready to fire.

I use a Knight Ultra-Lite .50 cal.

@sabotloader I am particularly interested in what you recommend. In the past you've recommended Bull Shop LGP .503" x 400 bullets with MMP Ballistic Base Sub-Base on top of 90 grns of ffG 777. Now that Idaho allows metal or metal alloy projectiles including accuracy tips and pressure bases, what is the best load?

Thanks!

-Tim

Since you can now use copper, I’d shoot a 250 or 300 ish gr Thor with 777 and #11 caps.
