1.125oz has more pellets than the 1oz. So with the same choke you'll get a denser pattern from the 1.125oz. Through your full choke you probably won't notice a difference in your score at the 16 yard line so it's really not worth thinking about.
At long yardage handicap 1oz of pellets is going to put you at a disadvantage. 1.125oz patterns back there are already at their limit (or a hair passed).

 

The 16 yard line is much more forgiving than the 27, so my vote is not too much difference. Handicap is a whole different ballgame once you get back there.

 

I've been experimenting with 7/8 oz loads instead of the 1 oz loads I usually use for practice. I don't notice much - if any - difference in breaks from the 16 yard line. If you have the gun pointed at the right place when you pull the trigger, the target will break. I'll still shoot 1 1/8 oz loads for trap league, but if I can practice effectively with a lighter recoil, less costly to reload round, it's all good. The pattern will be a little denser with more shot, but the size of the pattern should be the same.

I don't notice much difference in recoil between 1 1/8, 1 oz and 7/8.

 

Thank you gentlemen. At 70, I am just a recreational trap shooter, 150-200 rounds a week. Having fun. Like I said, didn't see much difference at the 16. Recoil wasn't much difference either.

 

When I returned to trap shooting after surgery I noticed in practice whenever I went straight for 25 I was using 1 1/8 7.5 not the 10z 8's I had access to.
It convinced me there was a difference even if slight.
Obviously anecdotal and others experience may be different.

 

1 oz of #8 lead shot has about 410 pellets.
1-1/8 oz of #7-1/2 lead shot has about 393 pellets.

 

The way I look at that is 1 1/8 oz of #8 is 461 pellets..

This topic always goes the same way, and it’s the same every time, ......someone wants to know the difference in pattern and effectiveness between 1 1/8 oz and 1 oz. “Not much”, they say. Then someone says they use 7/8 oz and don’t notice much difference between that and 1 oz. With that logic, you’ll eventually end up shooting 12 pellets.

To @Colorado 2018, if you don’t see much difference between 1 1/8 and 1 oz., then use 1 1/8 and it’ll pay off in targets even if you don’t always realize it.

Im a big supporter of 7/8 and 1oz 12ga target loads. But i did have to go to a tighter choke. My shooting did improve though...

 

There is a search feature on this site but no you ask the same questions with the same answers.

If you would poll the top 20 ATA Trap shooters in the nation right now , I doubt any are not shooting 1 1/8.
I would love for someone attending the coming Grand to get a definitive answer.

 

i shoot 1 oz of 7 1/2 shot at 1150 fps for all my singles shooting practice and ATA and 1 1/8 oz of 7 1/2 at 1200 fps for handicap practice and ATA

 

There is a difference in 1 oz vs 1 1/8 oz
1 Mere pellets = higher scores
2 higher scores = more confidence
3 more confidence = ( WINNING)

I still don't understand why some practice with 1oz loads or 7/8s then use 1 1/8s in a shoot. 1 1/8s all day ever day.

 

1. Less costly reloads
2. Reduced recoil
3. Refining your technique. Since you have less density in the pattern with a lighter load, it forces you to be ON target when practicing, improving results when competing.

Those are the reasons I can think of - there are likely others.

I don't know about trap, but I recently shot a sporting clays tournament using 1oz instead 9/8oz for the first time and did significantly better than usual. I've never thought of myself as recoil sensitive, but I noticed I felt a lot less fatigued at the end of the day after about 125 rounds. I might try it out on trap and see how it goes.

 

For 7.5 shot at 90% PE at target distance, the following diameters are the portion of your pattern that guarantees at least a one pellet strike. 7/8-6.4". 1 oz-9.8". 9/8-12". The differences narrow with higher PEs, and widen with lower at target break distance.

 

I've been shooting 1 oz reloads at 16 for over 20 years, Never felt
I was handicapping myself with a few less pellets. Broke 200
straight at the Grand with one oz. loads. For handicap, (24 yards)
I shoot 1 1/8 8's.

 

One of friends told me he , his wife and daughter shot 1 oz. loads for a year (the ladies were both All Americans). They dropped their average by 1 target. In my opinion, that's a lot for an AA.

 

Some of you guys can talk all the bullshit you want, but if you have 2 shooters at the same skill level, the guy using 1 1/8 will win in the end. Duh.

 

Ever notice the guys promoting light shot weights never post their name/ATA number and average ?

 

Maybe I'll worry about that when I'm AA.

 

Pbansen makes valid points. But practicing with less recoil could possibly have an Ill effect also. Not use to the recoil added to the confusion of a bigger shoot, Phil Kiners word not mine "pressure". I like to practice like I'm competing. 200 rounds with 1 ounce loads for practice i bet in a league, big shoot, even games, by the 100 mark people start getting tired because they haven't conditioned themselves to that load. Once your mind goes in a shoot it's hard to recover after your body is wore down too. I will practice with what I shoot at any sort of shoot. Train and practice the whole body not just a portion!

 

I've patterned 1 oz loads using modified, improved modified, and full chokes and compared the patterns to 1.12 loads using the same gun and chokes at 30, 35, and 40 yards. I like the looks of patterns using the 1.12 oz loads. The patterns appear more dense and have fewer holes. Therefore, I use 1.12 oz loads for all competition events. While shooting casual trap, using 1 oz loads may be ok for many. However, while shooting trap competitions, I prefer all the shot in my loads that are allowed. Confidence in your gun, choke, and loads make a difference when shooting trap competitions.

 

I'll just say this. In DTL trap we are limited to 28 gram (1 oz) loads other than for handicap.

I'd use 1 1/8 (32 gram) at 1150/1200 all day if I could.

When all is said and done, it's a significant extra % of lead in the air. I'd have it if I could.

 

If Leo shot 1 1/8 oz loads he must have had a reason to do so.
You do know a lot of his targets just broke from the fear of knowing they were getting ready to be hit hard, real hard.

 

FITASC is considered a harder game at big SCs shoots. A couple of years ago they went from 1 1/4oz to 1oz of shot. Everyone was up in arms believing the scores were gonna plummet. They actually went up - because there wasn't the big toll from recoil. Guess patterns different suffer too much. International skeet and trap both have a 7/8oz [ 24gram ] limit . I'd be willing to bet 16yd scores wouldn't change a bit. Good shooters are breaking birds with the center 20" of the pattern, not the fringe. There's plenty of BBs in that 20" pattern with 1oz of shot.

 

It is NOT a proven fact that scores went up because of the lessening of felt recoil, that is a very misleading statement. In fact most of the instructors in English Fitasc are of the opinion that scores went up because there was more attention paid to proper pointing of the target knowing they had to use a smaller payload. Another advantage was there was less muzzle jump which made acquiring the 2nd target of a true pair slightly easier. Felt Recoil was not the reason for the mandatory reduction.

 

I have been shooting 1oz for a while, thought I would give 7/8 a try, I notice no difference in the breaks, when I am on they break, when I miss they don’t. Also I don’t flinch. I don’t shoot registered so I am not loosing anything if I don’t break them all but I sure enjoy it more. I also shoot #8 so I have the same number of pellets in a 1 oz load as 1-1/8 have in 7-1/2. If I shoot handicaps I use #7-1/2 and my breaks are just as good as the guys using 1-1/8. Just my 2 cents worth.

 

You are not an A or AA class shooter, apparently.

 

Yea Tron,

Go beat Ray Stafford at dub's.

He uses a 1oz. 8 first shot in dub's.

Stick with making adj. comb's, you don't know shit about shooting

 

WOAH! How long to get that one before a Judge?

 

Yea,
He can come to Texas and we'll hash it out.
