I really don't think it was a rifle PM. I think it was an 8 bore shotgun. Barrels are too long to have been a rifle and weight is off. If it were an 8 bore rifle, weight would be up near 16 lbs.
Example: SN
22068, 8 bore Rifle sold on a French site. Barrels are on 28" chambers 3" Weight is 7.8 kilos = 17 lbs 3 oz

Here is a Reilly 4 bore wildfowler 18860, with stalking safeties. It apparently was proofed as a 6 bore and has 4" chambers which Donald Dallas says should not exist on a 19th century UK shotgun.

http://jamesdjulia.com/item/1363-396/Morphy has disabled all previous jamesjulia info on the web unfortunately. but the description of 18860 is interesting - i.e. proofed for 6 bore black powder:
MASSIVE FOUR BORE E. M. REILLY HAMMER WATERFOWLING SHOTGUN IN HIGH ORIGINAL CONDITION.
SN 18860. Cal. 4 bore. 4” Chambers. 42” Dovetailed stub Damascus bbls are engraved “E. M. Reilly & Co Oxford Street London & Rue Scribe. Paris.” on relatively narrow concave top rib. Bottoms of bbls are stamped with London black powder proofs for 6 bore and with SNs. Large nickel-plated Jones underlever action with non-rebounding peninsula back locks have round bodied serpentine hammers and back sliding safeties. Locks have four positions; fired, 8th cock, half cock, and full cock. Safeties engage at 8th cock. Action and locks are completely unadorned except for makers name on the tail of each lock. SN is on trigger guard tang. Lightly streaked and figured European walnut straight grip buttstock measures 14-3/8” over nickel-plated buttplate, and has classic point pattern checkering with mullered borders at grip, and a vacant silver oval on toe line. Matching splinter forend has shaped steel tip, and attaches to bbls with sliding side bolt through oval escutcheons. It appears this gun was made before chokes were invented. Diameter at muzzles is .952. Drop at heel: 2”, drop at comb: 1-13/16”. Weight: 18 lbs. 12 oz. LOP: 14-3/8”. CONDITION: Excellent, very close to new. Bbls retain nearly all of their Damascus brown with only slight silvering at muzzles, and some overall flecking. All other major metal parts retain nearly all of their orig heavy nickel plating, with only a few scattered knocks and a small bit of peeling at toe of buttplate. Action and trigger guard screws retain most of their orig case hardening color. Minor pins and safeties retain most of their orig fire blue. Stocks have nearly all of their orig hand rubbed oil finish with scattered marks and scratches, checkering very lightly worn and dark. Mechanically excellent, but triggers and locks are somewhat sluggish due to congealed oil. Bores are excellent, with some light scratches. Action is tight. Waterfowlers such as this are seldom found in this condition, because they are usually heavily used in salty environments. A superb condition example like this is a great rarity. 51401-5 MGM170 (20,000-40,000) ![[Linked Image from jpgbox.com]](https://www.jpgbox.com/jpg/63144_1024x557.jpg)
