Emotional roller coaster: 6 powder droppers in < 3 years!

I need to get the tip, but this thing was to get me through to the IP only, and you know that saga, but I was disinclined to tinker only to receive teh IP system shortly after I got it dialed.

At this point I feel like a fool for not dialing the V4 immediately, I have wasted soooooo much time waiting on the IP using inferior systems I don't want to tinker with

Accuracy International Picture Thread

MH and EO has AXSR .308 bolts stock. If anyones waiting or looking for one.

AB Raptor-10

I have limited experience with the raptor 10 I have, it's a .375 can with the reflex, I think it's 3", may be 4", i'm too lazy to turn around a measure it, i'm on my lunch break.

When I first brought it home, I stuck it on my 8 twist 308 with subs, and it's very noticeably quieter than my silencerco harvester I normally have on it, and the harvester is the quietest of all the others I have. The extra volume really helps the sound reduction. I haven't done any accuracy testing, or really anything other than listened to it for a few shots, giggled, and then said to myself I need to get off my ass and get the 375 raptor rifle build started....which I still haven't started...damnit.

308 Muzzle Velocity with 175gr

So, for reference, I'll list some info below of factory ammo I tried in my FN SPR with custom 22" barrel and some more testing with an FN PBR with its factory 24" barrel.

SPR 22"
American marksman 175 - 2703 FPS
PRIME Ammo 175 - 2538 FPS

PBR 24"
FGMM 168 - 2643 FPS
Norma Match 175 - 2592 FPS

I had multiple rifles that day and a bunch of different loads to test that I was going back and forth between rifles. When I got home, I realized I didn't test the same type ammo across both my 308s. It would have probably been good to see what difference it made.

Anyhow, the 22" had the highest speed with the American marksman ammo.

308 Muzzle Velocity with 175gr

Some of these loads for the 175 seem pretty hot, I would be careful and work up for sure. I have never shot 44.6gr of Varget under a 175 in a bolt gun, let alone a gas gun.
You're right, some of these loads are indeed "hot" and one should always be cautious and work up to "hot" loads since every gun is different in they way it can handle the ignition. :rolleyes:

Stupid question about recoil: 1 cartridge vs another

I can rationalize a case for both being the milder recoiling setup. The case for the BR would be less powder, quicker recoil pulse, but maybe a bit more jumpy. For the .243, a lower pressure charge and a longer, but smoother recoil pulse. I can also see how the difference woudn't amount to a hill of beans, as 2850fps is 2850fps.

As noted above, the amount of powder also adds to the recoil. Some of the initial ignition energy goes towards launching the powder column forward, adding to the total recoil.

There is something to be said for shorter duration recoil. The sooner the recoil is over, the sooner you can start to see what's happening downrange.
