Cooper phoenix
I recently purchased a Cooper Phoenix in 204. The groups tend to open up after the barrel warms up. The first group will be mostly all shots touching and then it opens up to 3/4" or so. I removed the action from the stock and there is what appears to be an intentional pressure point about three inches from the front of the forearm. Question, Do any of you have this same pressure point and has anyone removed in and received better or worst results.

rider,
I have 3 of the Cooper Phoenix rifles with no "pressure points" Heavy card stock will slide between the barrel & stock to about 1" in front of action (where the bedding stops) None of the groups will open up when the barrel heats up |

Usually warm barrels and pressure points will lead to vertical stringing. I would be willing to bet, if you remove the pressure point and properly free float the barrel your group size will stay small.

None of my seven Cooper rifles have a pressure point.

Pressure points have to be exactly made and tight fitting all the waty around the bottom and sides of the barrel or stringing happens as the barrel heats aad expands away from the pressure point.
I vote no pressure points. I go full float or fully Devcon bedded barrel from recoil lug to end of forearm, but the in between pressure point hasn't produced well for me. |

As soon as I have time I will remove the pressure point and test. This is the only Phoenix that I own. The two other coopers that I own are wood stocked and are free floating. Thanks for the imput.

The only pressure point on my Cooper was the price, but the performance soon eased that

Being as complete Cooperholic
with more than I'm willing to admit to, I have never had a Cooper that had a pressure point under the barrel. If you complain to Cooper, they will probably fix it for you gratis.

problem solved
I got off work early today so I loaded the Cooper Phoenix up and headed to the range. I tried some Berger 40 grain -two five shot groups in the 5/8 to 3/4 inch range. The groups are nearly round. These will need some tweaking. I then switched to the 39 grain B.K. which has always been my best shooting 20 caliber bullet in the 204. The conditions had improved and the 39 grainers grouped into a tidy group in the 3/8" minus range. The fliers that were present previously have disappeared. The powder with both bullets was 8208 XBR. 26.8 gr. for the 39 gr. B.K. which is definately max for this gun at 90 degrees. I will probably back the charge down to 26.0 grains for hot weather shooting.
Again, thanks for all the information. Rider |
