Unconstitutional SB 25-003 Gun Control Law Enacted in Colorado

CBS News reports: “Gov. Jared Polis on [4/10/25] signed into law what may be the toughest gun control regulations in state history. Under the new law, it is [now] illegal to buy, sell, and make most semi-automatic firearms [rifle, shotguns, and pistols] without background checks and training.”

The law imposes tough new requirements: “Individuals would need to pass a background check and receive an eligibility card from their county sheriff, who could deny it if he or she believed the person was a danger. Those eligible for training would need to pass a 12-hour safety course certified by Colorado Parks and Wildlife unless they have completed hunters’ training, and then it would be 4 hours. Their names would then go into a state database[.]” (CBS News)

The National Shooting Sports Foundation (NSSF) condemns the signing of SB 25-003 into law by Colorado Gov. Jared Polis. Under Colorado’s SB 25-003, sales of semiautomatic firearms capable of accepting a detachable magazine are banned unless those purchasing the firearms are vetted by a local sheriff and complete a firearm certification course. Sheriff approval to apply for a permit-to-purchase is based on subjective criteria. This type of regulation was expressly rejected by the U.S. Supreme Court in the 2022 Bruen decision that struck down New York’s unconstitutional concealed-carry permitting law.

“This law is unconstitutional on its face. It is a gun control group-spurred attack on the Second Amendment rights of those who follow the law”, said Lawrence G. Keane, NSSF’s Senior V.P. and General Counsel. Colorado’s SB 25-003 makes Second Amendment rights in Colorado only permissible with a state-approved permission slip. Along with banning ARs and other semi-auto rifles, SB 25-003 also bans the sale of semiautomatic shotguns and pistols that can accept detachable magazines, unless lawful purchasers obtain similar approval from county sheriffs and obtain a permit-to-purchase.

County sheriffs can deny an application if they have a “reasonable belief that documented previous behavior by the application makes it likely the applicant will present a danger to themself or others.” Sheriffs could also revoke purchasing permissions under the same standard. The criteria for the required training course is yet to be established.

Notably, SB 25-003 is unnecessarily burdensome, because Colorado gun buyers must already be checked and approved for a purchase through the FBI’s National Instant Criminal Background Check System (NICS).

BE SAFE: With Coated Bullets, Adjust Loads with CAUTION

Moly Danzac Bullet Coating Anti-friction HBN

Coating bullets with a friction-reducing compound such as Molybdenum Disulfide (Moly) offers potential benefits, including reduced barrel heat, and being able to shoot longer strings of fire between bore cleanings. One of the effects of reduced friction can be the lessening of internal barrel pressures. This, in turn, means that coated bullets MAY run slower than naked bullets (with charges held equal).

To restore velocities, shooters running coated bullets are inclined to “bump up” the load — but you need to be cautious.

Be Careful When Increasing Loads for Coated Bullets
We caution shooters that when your start out with coated bullets in a “fresh barrel” you should NOT immediately raise the charge weight. It may take a couple dozen coated rounds before the anti-friction coating is distributed through the bore, and you really start to see the reduced pressures. Some guys will automatically add a grain or so to recommended “naked” bullet charge weights when they shoot coated bullets. That’s a risky undertaking.

We recommend that you use “naked” bullet loads for the first dozen coated rounds through a new barrel. Use a chronograph and monitor velocities. It may take up to 30 rounds before you see a reduction in velocity of 30-50 fps that indicates that your anti-friction coating is fully effective.

We have a friend who was recently testing moly-coated 6mm bullets in a 6-6.5×47. Moly had not been used in the barrel before. Our friend had added a grain to his “naked” bullet load, thinking that would compensate for the predicted lower pressures. What he found instead was that his loads were WAY too hot initially. It took 30+ moly-coated rounds through the bore before he saw his velocities drop — a sign that the pressure had lowered due to the moly. For the rounds fired before that point his pressures were too high, and he ended up tossing some expensive Lapua brass into the trash because the primer pockets had expanded excessively.

LESSON: Start low, even with coated bullets. Don’t increase your charge weights (over naked bullet loads) until you have clear evidence of lower pressure and reduced velocity.

Procedure After Barrel Cleaning
If you shoot Moly, and clean the barrel aggressively after a match, you may want to shoot a dozen coated “foulers” before starting your record string. Robert Whitley, who has used Moly in some of his rifles, tells us he liked to have 10-15 coated rounds through the bore before commencing record fire. In a “squeaky-clean” bore, you won’t get the full “benefits” of moly immediately.

To learn more about the properties of dry lubricants for bullets, read our Guide to Coating Bullets. This covers the three most popular bullet coatings: Molybdenum Disulfide (Moly), Tungsten Disulfide (WS2 or ‘Danzac’), and Hexagonal Boron Nitride (HBN). The article discusses the pros and cons of the different bullet coatings and offers step-by-step, illustrated instructions on how to coat your bullets using a tumbler.
