Obviously a slacker who has failed to drink the PCP koolaid.

Well, since I now need to calculate the various BC to make this complication in my life work I bought a LabRadar. Optics Planet has them for $283 https://www.opticsplanet.com/labradar-doppler-chronograph.html

I agree, been a brutal winter. Whole days where the temperature never gets above 55f. Nights sometimes in the 30s. I have even had frost on my car one morning. Only going to get to 65f today. When will this horror ever end.

Been thinking about a DNT ZULUS LRF and spotted the Pard DS35LRF 1/2 off on EBAY. Out for delivery so I can play with it today

Just the adapter m30x1 to M18x1. I did the printed moderators last year and was unimpressed. Not great sound reduction and fragile. I broke a couple just banging them against the window frame. There was no issue with them holding up while shooting. But I print airgun stuff in PETG-CF filament...

Received an STO Falx big bore .357 moderator for my latest gunbroker win HM1000x .357. Had to print a m30x1.0 to M18x1.0 thread adapter.

What I used is the DonnyFl A83 adapter DonnyFL AEA CHALLENGER .22, .25 & .30 ADAPTER, 24” BARREL MODELS (1/2X20 MALE THREADS) A83 M28x1.0 threads on the shroud. I used my 0db 160 moderator. If you want I can do tests with my various other moderators Reximex Silent Force Long Silent Thunder...

I picked up 2 more rifles from a pair od Gunbroker.com auctions. HM1000X .357 and a BM500X .30 The HMX is, according to Martin Rutterford, one of 2 or 3 prototypes he made back in 2014. But both needed some work. The HMX literally had several rotten orings that I had to chase down all the...

When they first came out you could get the 4 pack of regular and heavy pellets (850) for $9.99. I ordered 4. Looking back I should have order at least 10 of the 4 packs. I was shooting .22 semiauto back then and went through a lot of pellets

Speed would vary a lot between the setups. Started out using H&N Baracuda 30.86gr but switched to JTS 25.39gr. Currently the .25 Condor is shooting JTS 25.39gr at 1,000 FPS with just 1700psi. Same plenum setup on the .22 18" Talon is 850FPS @ 1700psi with H&N Baracuda Match 21.14gr That...

Neither of which have anything to do with my original point. I have only ever heard that too large a plenum caused accuracy issues. Never have I heard that an unregulated gun has the same problem.

What was greater accuracy? Can you put a number to it? 1/3" became 1/4" At 25 and 45 yards with the same gun No reg/plenum Reg no plenum Reg small plenum Reg large plenum All I saw was the first and last were virtually the same FPS. No notable accuracy differences in any of the 4. But I was...

Yes, but the effect of a large plenum and a bottle are exactly the same for a given pressure. 120cc plenum, .25 24" barrel 19.3cc 220cc bottle, .25 24" barrel 19.3cc If both are at 2500psi what is the effective difference for that shot? Since plenum effectiveness with a direct feed gun does not...

What is an unregulated bottle if not a plenum? As to the point about shift, that is exactly what my original point was about. Claims that too large a plenum causes turbulence upon exit. My point being too large a plenum would be the same as unregulated. Both have sufficient air to accelerate a...

LOP is a little over 16 inches. Previous versions were almost 18. Still longer than the straight bottle & valve. Scope on the previous version had to be mounted all the way to the rear to get eye relief. Elbow has a good bend, but I am 6'2" or as an ex said 5'14" (she was 5'1")

Was perusing AliExpress and came across this: https://a.aliexpress.com/_mOGvGBR I would seriously think about it if I still had access to machine tools.

Yes, that is true especially with poppet valve guns. Not so true on direct feed guns, like AirForce. Yes, they have valve dwell but with some minor part changes you can actually push more air down the barrel than is required for the pellet to exit the barrel under acceleration. In that case...

Waiting on the leak test. This one may be set a bit hot right now. 1900psi on a .25 with 24" barrel. I'm guessing 1000fps or more with 25.39gr. The 1.1L bottles were more about their length than their volume. Limited space from the U-valve to the hand grip. The 0.48 is shorter and fatter than...

I have had multiple discussions with various air gunners about plenum size. There is a belief that too large a plenum will cause turbulence at the barrel end when the pellet exits. Not having ever experienced that I have always been a bit skeptical. I realized in the middle of the night that...

I found some 4500psi 20cm long 120cc volume tubes on Alibaba a while back. Normally they come with an air gauge on one end and an M18x1.5 adapter on the other. I ordered them with M18 at both ends. The Shan Bao 20cm tubes I have been using are rated for 3000psi. So the extra headroom is a nice...
