Ballistics on a 10.5" barrel???

[parishioner]

My 11.5'' is loaded with 62 gr. Federal JSP.

Where are yall finding the 62 gr. Federals? My searches keep turning up forum discussions about it.

I had the same question, when we were spec'ing 10.5" barrels for use on our police department. This is the Information I recieved from Gene Swanson at Lewins Machine and Tool. I hope he doesn't mind me throwing him out there like this.

"With a 55gr bullet and the 10.5 inch barrel, your looking at about
2600fps at the muzzle. At 100yds it's roughly 2300fps. The 16 inch
barrel will be around 2800fps at the muzzle and 2500 at 100yds."

11.5" or 12.5" would get my vote. It depends of course on what you estimate your maximum distance will be. I have a 10.5" & 11.5" guns. If I could only have one I would keep the 11.5" because of the increased dwell time. I am in VT and I've heard the cold can effect reliability any one had issues related to the cold?
