I've used aluminum gas checks in my 30-30 and '06 rifles for a number of years now and have had no problems at all. I only use them at speeds of 1500 fps or faster, up to 1900 at the fastest, and they have been accurate and economical, what's not to like???

Wouldn’t get too excited about ordering from them. Just got my first and last order.
The ad is how they have it listed above and this is what they sent me
Super rough cut and uneven edges like a smashed bottle cap versus the ones that they have listed on their website that looked just like a hornady gas check with even edges. I would Assume most people buy once from them once and find out the lack of quality.
Here’s a few I squeezed on. They actually went on pretty easy and I was kind of impressed. They still have uneven voids around the boolit base. Probably not enough to worry about though.

Copper fouling can build up in a bore so high you can see it. That can damage lead bullets fired after. The only time I've had this happen was from shooting thinly copper washed/plated bullets; the cheap Remington green/white boxed pistol ammo sold at Walmart. It doesn't come out with normal brushing.
You satisfied your own worry. The bottle cap gas check has tremendous GRIP and STAYS ON. The check won't sail into the sky screen of your chronograph. The bottle cap grips after sizing with significant positive force.
EVERYTHING shot down a bore does some minute amount of damage. Aluminum gas checks are neither corrosive nor more or less harmful in any other way than Heat, copper, and lead. Before you ever see or experience a worry with an aluminum gas check, your barrel will be shot out from heat and projectile damage and I doubt most of us will ever get to that stage of shooting a single gun.
If it was easy, anybody could do it.
