Tubed Trapgun

What do you think of a 32 inch trap gun tubed down to 20 gauge. A lot of shooters are now running 7/8 ounce loads due to economics and recoil. I am thinking a 3/4 ounce load at about 1250 to 1300 fps of 7 1/2s through an improved modified for 16 yardline.
 
Why not just shoot 7/8-oz in a 12-ga?
I was shooting trap this afternoon with a fellow who was crushing 16-yard targets with 7/8-oz 12-ga loads.
For 3/4-oz you might get better performance from 28-ga loads. But, the 28s would cost more than 20s.

Doesn't add up to me

Going from 7/8 to 3/4 oz. loads saves you about 1 oz. of lead per 8 shots. That’s about 5 rounds of trap to save a pound of lead. In the past few years lead has almost doubled in price depending where and how much you buy. That's an increase of about 80 cents a pound.
I don't know what a single tube would cost but it looks like you would have to shoot several hundred rounds of trap just to break even.

Or did I foul something up, I never was very good at math....................
 
Like others said - just shoot 7/8 oz loads in a 12ga / why bother going to the expense of tubing a Trap gun ....
 
Most shooters who used sub-gauge adapter tubes do so in order to use the same gun for 12 gauge and 20 gauge shooting, not because it works better or saves money. If serious shooters were concerned with saving 5 cents per round of trap, they would not buy $5,000 shotguns.
 
From the 16 yard line - you can shoot 8's or 9's / and you don't need a shell at 1250 - 1300 fps let alone 7 1/2's .... / and at 7/8 oz that will give you a better pattern density than 7 1/2's ( vs 7 1/2's if you use 8's in 7/8 oz it'll give you 56 more pellets / and in 9's it'll give you 118 more pellets in a 7/8 oz load ....)

1200 - 1225 fps is plenty fast enough for 16 yard Trap / and 8's will give you plenty of energy to break Trap targets at that kill range of 30 - 35 yards.

The guy Zippy13 was talking about was shooting 7/8 oz of 8's in a 12ga at 16 yards yesterday ...at 1200 fps( I just talked to him and verified his reload recipe).

Almost all the loads I shoot these days are 7/8 oz loads, out of a Beretta O/U and varied 870s. All are 12 gauge save one.

The Geezers are fond of 7/8 oz loads in 12 gauges and we break birds from behind the 27 yard line at Chinese trap and other games.

I get about 450 loads from a bag of shot.
 
I'm just wondering if that's a reliable combination that could be made to work. I have probably 750 rounds of 7/8 ounce made up at any given time. As far as smaller shot, if I run out of 7 1/2s I will go to eights but I do not think thats happened in the last 30 or 40 years. 1971 in Spain I used a couple of boxes of eights.
