Paul,
.035 is full in 10 ga .025 is called improved modified in 10 ga from the charts I have. .030 is an improved/improved modified better know as a light full choke I believe. If I want to shoot light loads I'm using gold gauge mates to shoot the light 12 gauge loads that I have a lot of and are easy to make compared to using up my 10 ga hulls and components, but that's just me. Shooting 7/8 ounce for practice. You would be amazed at the full choke patterns with a very light load. |

The 2 5/8" 10ga has less internal volume than the 2 7/8". This means less filler wad is required. Heavier loadings like 1 5/8 and 1 3/4 ounce may not be possible (or advisable). A plastic wad may not be able to sit deep enough to allow for a star crimp, forcing a roll crimp or the trimming of the petals to make room for a star crimp, or use of nitro card and filler wad combination instead of plastic wad. Use the 2 7/8" Sherman Bell recipes that are low pressure and experiment with the filler wad to get the shot column height correct. Us Short Ten and Shortier Ten reloaders are a little more on our own than loaders of other gauges. The good news is that big hole is very forgiving. |

It takes more constriction in a bigger gauge for the same choke. I just found some data on chokes that's a little different than JA's. For the 10 it's .045/full and .030/mod. so I must have a mod choked gun. I have the Gold and Silver Gauge Mates and feel it was a waste of money to buy the Golds. Other than a case and brush the only difference is some of the lip is missing on the Gold. If one simple grinds off half way around removing some lip on the Silver you'll have a Gold that allows a shell to be removed while still in the chamber. George, my 10 is also 2 5/8. The chambers don't have a forcing cone but a step at the end. Believe it was made for brass shells. A brass shell would butt up against the step. That way a wad would be a perfect fit for the bore. If you think 7/8oz has a tight pattern, go to 3/4oz. Claybusters has a 3/4oz 12ga wad - call them and they'll send a free sample. Paul

I knew someone would give me that wise guy 1/4 inch answer. I should be someone's setup man. Historical question: Why and when was the 2 7/8 started? My 2 5/8 was bored in September 1895? Was 2 7/8 available or in use at at that time? |

Here is an interesting article on the history of the 10 bore that answers your questions in a general fashion. http://www.wildfowling.co.uk/magazine/tens.htm |

Back in the day, many shells in different lengths were offered. Most gun makers would offer chambers to any length. Parker also offered different chamber diameters for brass or paper shells. Paul

Paul,
I agree that it does seem strange to show the same restrictions for 10 GA as 12 GA, but I had only two charts that listed the 10 and both show the same as 12 GA, with three exceptions of I.C., Skeet II, and M. One of the charts is on this website. http://parkerguns.org/pages/faq/ChokeSize.htm I'm happy with the 10 to 12 Gold Gauge Mates for they do stay in place if one uses enough grease on them. If you shoot higher pressure loads in good reloadable cases (WWAA and RP STS), it blows out the sides of them. But I'm shooting a 24 gram load with 3200 psi and it leaves a crease but does not make them useless. |
