P17 Project, 25-06 Rem
@ 07:52 pm (GMT) |
Ben GradyHi Guys. I going to ditch the last thread on "re-loading help needed" and start this new one.Just an update, if anyone was slightly interested in this thread. 25-06 Rem on a P17 (M17) Action. My load development stopped as I had a elbow operation but now I a am ready to go. Just to re-cap. I had a new heavy Bradley Barrel fitted. Original groups were bad 11/2 -2+". I docked 15mm off the end of my barrel because Chris Murphy saw tooling marks right at the muzzle. Straight away groups dropped and the Federal 117gr factory ammo was 4 shots touching and fowl shot not far away. My home loads were about an inch group. There was also fouling along one of the grooves so I have hand lapped the throat in case there was a reaming burr. Velocities were high but no pressure signs showing at book max. I have now added a suppressor as I have a 11 month pup T J, who goes hunting with me. He has started indicating which is neat. I don't want him to become gun shy. He doesn't flinch with my mates suppressed 30.06 going off. So a trip to the range to re-sight it in and tinker loads is called for.

Nathan FosterRe: P17 Project, 25-06 RemCertainly looks like it has come together nicely Ben.Keep in mind that just ahead of a suppressor, the noise can be such as to deafen a dog over time (depending on the actual suppressor design). Most hunting bred dogs won't flinch, the greater problem is having the poor souls go deaf. So do try to keep the dog at heel when you shoot if you can. The side and rearward suppressed noise can sometimes (again depending on the suppressor) give us a false sense of what is going on out just in front of us. |

Ben GradyRe: P17 Project, 25-06 RemWell I couldn't access the range I normally shoot because it is in the middle of a pine forest in marlborough where we have had no rain and three big forest fires lately. So I went to my hunting block with the suppressor on the 25 06 for the first time. With difficulty I finally found a spot that I could set up a 100 yard target range that was reasonably level. I was shooting off the bi-pod prone, holding the forewood. It wasn't until half way through shooting that I remembered that Nathan suggests holding on the scope. Not wanting a variable I carried on holding the fore end. First three shoots was to get it close to where I wanted it on paper using Federal Factory 117gr ammo. The next three shoots with the Federal ammo was a 19mm group. Mirage was a big problem as it was 10am and 24 degrees and getting hotter. The north west wind had also picked up as well but was coming from behind me, so not too much of an issue.
Next I tried my hand loads that were around 3200 fps last time at the range. And a OAL of 72.35mm. This time I had seated deeper to 72mm to see if any affect. 19.45mm group 
Adjusted the scope to try and get 2.1 inches high @ 100yards (Zero @250 yards). 
Pretty close so then tried more groups through the chrony. 
And then the last three shots quick fire after the last three. Just to see what happens. 
No pressure signs that I can see, easy bolt lift and easy extraction. 
The chronied speeds were still high 3310, 3219 and 3194. Then with the very hot barrel after quick fire 3099, 3442 and 3432. More like .257 Weatherby speeds but maybe it's a fast barrel? It is a 25"very heavy, less than 50 rounds fired barrel. I also had hand lapped the throat of the barrel because after each shot in the past there was one of the grooves with bad copper fouling to the muzzle. This seems to have been fixed. Yahoo. Are the high velocities a concern? Now once it rains and I can get back to the range, I will be able to fine tune my loads. But I am very happy with the way things have panned out. Many thanks To Nathan and Chris Murphy. |

Bob MavinRe: P17 Project, 25-06 RemHi BenAm I reading that correctly 3099, 3442, 3432fps & 3310, 3219, 3194fps, that's a lot of variation in velocities? I'm surprised your getting accurate results. Cheers Bob |

Ben GradyRe: P17 Project, 25-06 RemHi BobYes I agree with you. I am not that savvy with the chrony yet, After each shot I would write the speed down. After I had written it down, some of them came up with ( error ) on the screen. But I didn't want to re shoot as it was a stinking hot day, in bright sun light, No shade and the target at only 100 yards was a blurry mirage. It was hard shooting and the barrel was heating up fast. So I decided that I had enough evidence that things were good and It was sighted 2 inches high at 100 yards so it is good to good for hunting medium ranges. And that once we get some rain I can get to the range and shoot off the "Caldwell Rock" front rest and sand bag back rest. Which should help even more. In hindsight I should have marked the ones that came up with "error". I am still thinking my loads are around the 3200fps mark. Could they jump up to 3400fps because of a hot barrel?. I know Nathan isn't happy with my velocity of 3200fps, but it seems a safe load at book max, no pressure signs that I can pick. Will keep posted once I can get to the range. |
