I used your 16ga. to 28ga. tubes at the recent Grouse Hall ‘Vintagers’ sporting clays shoot. The gun is a very light Belgian 16 gauge hammer gun with ‘Krupp Fluid Steel’ barrels. While the gun is great to handle and fits well, it becomes very uncomfortable to shoot, even with 2½-inch shells due to recoil. Your tubes transform this firearm to a real joy to shoot. After a total of nearly 150 rounds, the tubes worked perfectly. About half of the round was shot with Winchester AA factory 28 gauge loads; the other half with AA reloads. Later, patterning both barrels produced unexpectedly good results. I use digital pattern photos and analyze them using a computer program from shotgun-insight.com. The normal distribution ‘hit probability’ inside 30 inches at 25 yards is 99.9% with the full choke Barrel and the pellet distribution under the ‘bell curve’ is as good as it gets. The full on hit probability with the nearly cylinder bore barrel is 98% to 99.5%. These are impressive results.

The following week I took this gun to Lehigh Valley Sporting clays for a shoot. This course is very demanding, even for a 12 or 20 gauge. I used the new Winchester AA 28 gauge ‘Super Sport’ sporting clays 7½ ammo, factory rated at 1300 ft./sec. It seemed faster! I did as well with your 28 gauge tubes in my old 16 gauge as I have ever done with a 20 gauge. After 150 rounds of intense shooting the barrels were hot but the shoulder was not sore at all.

Your tubes re-vitalize old, lightweight game guns, making them a pleasure to shoot while getting competitive results. I cannot wait to try a pair in my 12 gauge hammer gun.

Thanks for a great product.

I recently bought some 12-20 gold adapters from your company. To say the least, I am thrilled with the results I get from them.

Typically, I shoot starlings at a dairy three times a week during the summer. When shooting a regular 20 ga. gun, I find the effectiveness limited to about 30 yards unless I choke way tight. Then I give up any margin of error on close birds.
I have shot around 110 birds this week through an O/U with .010 and .020 chokes. My longest bird fell at 62 long steps so I figured with the momentum he may have traveled another 10 yards. So that is a long shot for a 7/8 oz load. It is a real pleasure to shoot with the GMs and patterns surpass any expectations. I do find that AA cases, the old ones, release from the GMs much easier than the Remington STS while shooting reloads.

I think it is a wonderful product.
