2 3/4 dram
I guess we need to the disclaimer thing i.e. have a competent gunsmith check your gun...
As to a Trojan or VH with 2 3/4 drams, that is far below its proof value for a 12ga. And, I have shot a few thousand rounds of 2 3/4 out of my VH. Not an issue. Both Vulcans and VH use modern fluid steel barrels. As to spreader loads, they have a mixed reputation. I know people who use them, but I also know people who have pattern tested them and found really big holes in patterns. an ounce with 2 3/4 dr eq of No. 8 should do just fine. Mine is Mod/Full and has not been a problem for Clays. |

Fullchoke16, please let us know the specifications of the Federal Top Gun loads that you find uncomfortable. The loads suggested by the original poster should not be abusive in any Trojan.

Bill, You're right. I dug out a box of those Top Gun Federals and they are labeled 3drams, 1 1/8 oz. not 2 3/4, 1 oz. Fred

I'm not aware of any 12ga Parker that was not intended when made to handle a 3 dre, 1 1/8oz load, both in recoil and chamber psi. Obviously, a person may choose for a variety of reasons to use a lesser load.

12 gauge Parkers back into the teens were often pattern tested at the factory with 3 1/4 DE, 1 1/4 ounce loads.

This is out of the Parker Story, Volume 2, page 515 and is for 12 gauge 2-5/8" chambers. TPC states that the article states that Parker adheres to the standards in the table.
Nominal Chamber and shell length - 2-5/8" Theroetical Service Pressure limits Based on Definitive Proof Pressures Mean: 9800 Maximum Individiual 12,000 Service Working Limits for Factory Loaded Ammunition Mean: 9500 Maximum Individual 10,800 Notes on the table say that the units I gave are pounds which I take to mean psi The table was in a 1934 article One of the notes in the table said that the limits are based on 1925 British Rules and Regulations I surmise that the psi and ton pressure measurement are in LUP which I think stands for "lead units of pressure." One of Burrard's volumes has a conversion for LUP to electronic pressure measured units. I have never been able to confirm that the table this is taken from is in LUP. I shoot Federal Top Gun 2-3/4 dram 1-1/8oz loads in my Parker VH 98XXX, 7-1/2s and 8s. This gun is 2 frame with 30" barrels and weighs 7lbs 13 ounces. It had the chambers lengthened to 2-3/4" before I got it. I have measured the chamber wall thicknesses at the end of the chamber and the thinnest is .110". I use the gun for clays and for field trialing. My gun was made well before 1934. You pays your money and you takes your chances. Best, Mike |

Yes, Bill is correct, Mike is correct and I'm correct in the above statements. Yet, these issues consume discussions and questions on this forum and we have never had whatever it takes to produce a unified statement in a FAQ or guideline. That has been a source of frustration for me for years. Somehow some people believe that by stating what Parker did is somehow the PGCA sanctioning present day actions by people who may or may not have guns that are suitable to stand the same loads today, and we seem to be unable to resolve that issue.

And here is the 2-3/4 DE 1oz Federal Top Gun:
http://www.federalpremium.com/produc...ll.aspx?id=671 One summer when I was shooting a lot of clays I ordered in a pallet of these and I think they are great. And here is the Top Gun 2-3/4DE 1-1/8oz which the Gander Mountain here usually stocks: http://www.federalpremium.com/produc...ll.aspx?id=446 These are the shells I usually shoot in my old VH.
