Sighting in double rifle

[mitch4570]

Ok I have my chapuis regulated about 2 1/2 inches at 50 yards. Now I will sight it in. I am planning on adjusting my sight for the impact from the right barrel. I always pull front trigger first. To many years of hunting pheasants with double shotguns to change now.
So what do the experts here say. Sight in to impact of 1st shot or split the difference?

I always sight in with my right barrel ensuring second barrel will hit with established regulation. Don’t over think it. Anything within 50 yards will be dead if first shot on target with second barrel follow up

Agreed, with above it makes sighting in an RMR easy and conserves ammo.

Would be interesting to see your regulation target when you mention “regulated about 2.5” I had a long conversation about loading for double rifles with Ken Owen and his methods of tuning by velocity.

 

[mitch4570]

Here you go, it's a 470 N.E. quess thats 2".
I hope I can get swift A Frame to regulate this well. I am healing up from a hip replacement and have not been able to get to the range yet. If the Swifts don't work out the woodleighs will get the job done.

I do the same.

Nice, FYI if your rifle shoots Woodleigh well I’d be willing to bet it shoots Hornady well enough for cheaper and easier to source practice.

Roger that just picked some up at a good price. They are not bonded but will make good practice ammo.

I’d zero for the first shot. That’s always the most important one.

However, I don’t think it’ll make much difference which ever way you go.

Sight in to impact of 1st shot. 50 yard target, Green Shade is 1st shot (right barrel) off sticks, Merkel 140 AE .470 Nitro:

Thanks for everybody's advice. Appreciate it.

Yep, I source the old non bonded ones for practice too; usually pick them up off gunbroker for $70ish a box.

FYI - the factory seconds that pop up on Midway occasionally are good practice also.

Learn to use the back trigger first or you will either double or pull front trigger twice at some stage. It will likely be in a tense moment. Ask me how I know!
You will want the left barrel to be right on for that first shot. Be less concerned about follow up shots but that first one on any animal is most important.

 

[mitch4570]

I have heard both ways. The PH i've booked with in 2027 pulls back trigger first. The gunsmith that worked on my double says front trigger first.
I shoot skeet and hunt pheasants over dogs with double trigger sxs shotguns. So 3000 to 5000 rounds a year of building strong muscle memory. I'm afraid if I pull the back trigger first I will just naturally move back and be pulling the trigger guard.
I'm interested in what others have to say on this topic.

Front trigger first is correct. If it wasn’t they wouldn’t make the back trigger a slightly heavier pull. Your hand naturally moves back to the second trigger as well. Stick with doing it the right way.

@mitch4570 Like you i grew up shooting SxS and have a many 1000's of rounds of muscle memory.

if you check the trigger pulls in 99% of the cases I have ever checked (Double rifles and shotguns) the Front trigger has a lower trigger pull weight and the back heavier. Designed that way to prevent doubling as sears and trigger wear in. If you are used to it I would stay front trigger first. Just make sure you pull the trigger to the rear and hold it through the recoil cycle. That will prevent the Strumming of front to back trigger for the dreaded operator error doubling of the rifle. which is what @Philip Glass was talking about I think.

Not what I was taught at all. Always front trigger (right barrel) first.

I understand but it doesn't work when you get on DG. You will, at some point when it gets tense, pulling the front trigger twice. Unless you been shooting double triggers for many, many decades.
How many people double? You can't pulling back trigger first. It is what it is.

I get your feelings on double triggers. Lots of people have trouble with double triggers and as someone who has used them my whole life it’s hard to fathom. It’s so natural to me that with a double shotgun hunting pheasant I prefer skeet or cylinder in the right and full in the left. If a bird gets up at 40 yards I’ll fire the left without any thought at all. I would be concerned using a double on dangerous game, regardless of which trigger first, if I didn’t have that natural muscle memory. I’ve seen so many trying to bend the first trigger after a miss on a bird rather than changing triggers. There are a few DG videos I’ve seen where the client does that also.
Bad thing is folks that aren’t used to double triggers are likely to never shoot a big bore rifle enough to get the hang of it to the point of not thinking about it. Saw someone else recommend skeet shooting with two triggers, that would probably work.

All this front vs. back is utter nonsense. Index on front--middle on back. Pull both. Fire for effect.
