Barrel switch

[Don McDowell]

Sounds great!

Sounds good Kurt. Seems its all coming together nicely.

J.B. yes it is. I think it will make a fine combination rifle.

Don, Kurt, your concern about wear caused by swapping the barrels back and forth on the CPA action has made me curious as well. The place that I figured had the most CPA users on it is the ASSRA board. So I posted a question as to if they have seen any changes from swapping barrels over the years. I haven't gotten many reply's back yet as I only posted it this morning but the one reply I did get back seems to indicate that it is pretty much a non issue. The reply is "My 1993 CPA Action has been switched rim to centerfire perhaps 3 dozen times a year for 21 Years. No change at all in how it takes up or shoots."
I hope this makes you feel a bit more comfortable about the barrel swapping. If there are more reply's both positive or negative I will post them on here for your viewing pleasure.

Thank you Sam.
I have been searching the internet about comments about the CPA rifles but I don't find much. Some comments about good accuracy and some comments on wood metal fit not being too good.
All in all what I read has mostly been positive.

Your welcome. Yes I agree the wood to metal fit can leave just a little to be desired. On mine I have some glass on the upper and lower tangs and there is a large gap between the forend and receiver. Some might be upset about that but for me it means that there will be no contact and I can live with it. Mine shoots probably better than I can hold it. My only gripe is that it shoots off to the left and I have the front sight moved over accordingly. Maybe one of these years I can make it up to Pauls shop and have him tell me why its like that.
Other than that it is a good solid rifle, its accurate and easy to maintain.
I have had mind since the late 90's, don't remember the exact date. The serial number is in the mid 500 range. The only problem, mechanically, I have ever had with it was a broken firing pin. That happened shortly before a bit match. A phone call had a new pin in a couple of days. I was told when I called that it was a common problem and that what I really needed to do was to send the block back and it would be fitted with larger firing pins. I did that after the match and have not had a problem since.
My Shiloh on the other hand, hasn't had a problem at all. I am very happy with the extreme quality of American made and American backed single shot rifles available today and the fine people that make them.
Since my post from last night, I have had one other response on ASSRA and it was also posative, no problems with switching barrels on a 2000 model.

My bet it's a class '3A or 3B' thread fitment used, and not your std class '1A or 2B' thd.

Sam.

One thing I have noticed on mine is the firing pin does make a deep impact on the primer and it has stuck in the detent and shows sign of dragging out of the dent and I can feel it when I drop the lever sometimes. I have since put the hammer on halve cock like I do the Sharps and this problem has stopped.
Using Fed pistol primers the dent is really deep almost like my Trapdoors will dent the harder CCI rifle primers. I quit using the pistol primers in the CPA. Cant really see any difference in accuracy using them over rifle primers in this rifle.
I'm going to give them a call about the pin problem. I need a pin that holds the extractor on the lever anyway for a slave pin making the block change easier.

Gary I don't know what the thread is bit it is a very good fit.

Kurt, the firing pin problem at that time was due to its size, they have since gone to a somewhat larger diameter pin, thats why they had me send my block back. As to the pin dragging, that is something you will have to take up with them. Yes getting things lined back up when you change blocks can be a bit of a pain. Slave pins are the way to on from what I have heard over the years. All in all, the CPA is a pretty good deal in this day and age
