有关戴铣的文献记载，最早当属清乾嘉时期着名学者纪晓岚所撰《阅微草堂笔记》一书，此书成于嘉庆三年(1798年)，刊行于嘉庆五年(1800年)，其中卷十九《滦阳续录(一)》记载与戴梓的后人戴遂堂交谈时，遂堂“言其先德本浙江人，心思巧密，好与西洋人争胜。在钦天监，与南怀仁件，遂徙铁岭。故先生为铁岭人。言少时见先人造一鸟镜，形若琵琶，凡火药铅丸皆贮于铣脊，以机轮开闭。其机有二，相衔如'}牡，扳一机则火药铅丸自落筒中，第二机随之并动，石激火出而铣发矣。计二十八发，火药铅丸乃尽，始需重贮。拟献于军营，夜梦一人诃责日:‘上帝好生，汝如献此器使流布人间，汝子孙无憔类矣。’乃惧而不献。
说此事时，顾其侄秉瑛日:‘今尚在汝家乎?可取来一观。其侄曰:‘在户部学习时，五弟之子窃以质钱，已莫可究话矣其为实已亡失，或爱惜不出，盖不可知。然此器亦奇矣。”
戴梓（1635年－1704年），戴梓后代戴遂堂说起这件事时，距离戴梓死已经94年了。

这把是步枪，连珠铳
The workings of the 17th century Lorenzoni magazine flintlock, rotating the lever delivers ball and powder from tubular magazines in the butt.
Object Type
About 1650 a type of repeating gun was invented in which the powder and ball were carried in two tubular magazines set into the butt. It also had a cylindrical breech-block that rotated on an axis set across the line of the barrel. The system is named after an Italian gunmaker, Michele Lorenzoni, who is recorded as working in Florence around 1685. He made several repeating guns of this type.

Method of Operation
Two tubular cavities are fitted into the butt, forming magazines for powder and ball. In front of this is a revolving breech-block with a lever on the left side, turning at right angles to the axis of the barrel. This breech-block has two hollow tubes corresponding to the openings of the two tubular magazines.

In front of this is a revolving breech-block with a lever on the left side, turning at right angles to the axis of the barrel. This breech-block has two hollow tubes corresponding to the openings of the two tubular magazines.
To load the gun, the muzzle is pointed downwards and the breech-block is revolved half a turn, using the lever. This aligns the two magazines and chambers in the breech-block. By the force of gravity, a ball and charge of powder fall into the breech-block. This is then turned in the reverse direction using the lever. The ball drops into the breech of the barrel and aligns the powder chamber with the barrel. At the same time the flash-pan is primed with fine powder from a separate magazine. Two projections on the breech-block push back the lock into the 'half-cock' position and close the pan-cover. The cock is pulled back to full-cock and when the trigger is pulled the gun fires. This process is repeated each time another shot is required.
Maker
John Cookson made several repeating guns based on this system. He signed one 'Fecit Londini', which suggests he was a London maker though no trace of him has ever been found in any of the London gunmakers' records.

Another John Cookson, who was also a gunmaker, is known to have worked in America. He is recorded in Boston, Mass. between 1701 and 1762. In 1756 he advertised repeating firearms firing nine shots in the local paper, the Boston Gazette. It is probable that he was related to the John Cookson who worked in London.
17-19世纪，欧美各国发明了各种各样的可连击枪，以上只是其中的一种。在没有定装弹的时期，连击枪的使用很困难，也很不可靠，这是它没有普及起来的原因。
回复删除戴梓的后代不过是见识了其中的一种而已，就吹嘘出一个祖先很伟大的故事。
更可恶的是为了衬托戴梓的伟大，使劲往南怀仁身上泼屎盆子。
紀昀《閱微草堂筆記》卷十九，曰：“戴遂堂先生讳亨，姚安公癸巳同年也。罢齐河令归，尝馆余家。言其先德本浙江人，心思巧密，好与西洋人争胜。在钦天监，与南怀仁忤（怀仁西洋人，官钦天监正），遂徙铁岭。故先生为铁岭人。言少时见先人造一鸟铳，形若琵琶，凡火药铅丸皆贮于铳脊，以机轮开闭。其机有二，相衔如牝牡，扳一机则火药铅丸自落筒中，第二机随之并动，石激火出而铳发矣。计二十八发，火药铅丸乃尽，始需重贮。拟献于军营，夜梦一人诃责曰：“上帝好生，汝如献此器使流布人间，汝子孙无噍类矣。”乃惧而不献。说此事时，顾其侄秉瑛（乾隆乙丑进士，官甘肃高台知县）曰：“今尚在汝家乎？可取来一观。”其侄曰：“在户部学习时，五弟之子窃以质钱，已莫可究诘矣。”其为实已亡失，或爱惜不出，盖不可知。然此器亦奇矣。诚谋英勇公因言：征乌什时，文成公与勇毅公明公犄角为营，距寇垒约里许。每相往来，辄有铅丸落马前后，幸不为所中耳。度鸟铳之力不过三十余步，必不相及，疑沟中有伏。搜之无见，皆莫明其故。破敌之后，执俘讯之，乃知其国宝器有二铳，力皆可及一里外。搜索得之，试验不虚，与勇毅公各分其一。勇毅公征缅甸，殁于阵，铳不知所在。文成公所得，今尚藏于家，究不知何術制作也。”
