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!

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

Yes, I am particularly interested in 100% copper bullets, so I'd love to hear everyone's recommendations.

What would be better for elk, the hollow points or ballistic tips?

I’d go with the 297/300. I don’t think the tip makes a lot of difference. The 250s are too light in my book for elk.

I went with the Powerbelt 338gr Platinum Aero tip; it shoots well, but no animal results at this point.

Ok. What is the difference between the 297 & the 300? Why do they bother producing two different bullets that are so close in grains?
