So I recently made my first purchase with Lee spring, luckily I use a prepaid card and plan for purchasing because my original order was $46, I was charged $24 and part of the order shipped the other day now this morning they tried charging another $56, wtf 46-24=22 right. So I call and got the run around from 2 people then transferred to the big guy I guess and what a load I got, OK 2 shipments from 2 warehouses makes sense but about the additional charges he goes on to say how that's how there system works but in the end of the day it'll correct itself. Yeah right. The reality is someone thought I'd be a big company with lots of charges because of the variety of my order and they could get away with some extra because there's no way I'd be looking. We'll lucky I do look and plan for purchasing so there's not much extra there and they got declined.

With an FFP (first focal plane) scope, the reticle changes size with the zoom, while keeping the angular measurement (MOA / MIL) presented by the subtension references constant. With a SFP (second focal plane) scope, the reticle does not change size but the angular measurements (MOA / MIL) from the subtensions will change proportionally if you zoom in or out from the calibration magnification.

With BOTH FFP and SFP scopes, the position of the center of the reticle (crosshair) stays constant. If it's zeroed at your shooting distance, POA = POI (point of aim = point of impact).

So, with a SFP scope, look to the manual for the subtension angular measurements AND which zoom setting it's calibrated for. My SFP scope, a
Hawke 4-16x44 Airmax 30 SF Compact, for example, is calibrated at 10X on the zoom. So, the "mil dots" on my scope reticle represent a 1 mil angular measurement... at 10X. If I change the zoom from 10X, then I have to do some math to figure out the angular measurements between the dots.

View attachment 576587

So when I'm doing a zero, or if I want to use my reticle subtensions to calculate bullet drop and use the hold-off method instead of dialing, 10X on the zoom (where the scope's reticle is calibrated) is going to make that much easier. Again, look to your SFP scope manual to find the magnification for which the reticle is calibrated.

With a FFP scope, again, the measurements between the subtensions are constant at any magnfication.

I hope that made sense!

Hello,

I already have a 74 cubic ft Carbon tank but was looking to buy a 98 ci carbon bottle off eBay. It was manufactured 11/23. I'm not sure of the brand.

I have heard the small bottles tend to leak; it is allegedly good to 4500 psi (same as my 74 cubic ft one). Has anyone had luck with the small bottles? Thanks in advance!

Interesting thought, kind of like a million miler in my work industry. No way I’ve shot even close to a million. Have drove over a million for sure though.

Well, the saga continues.
Today I tried pellets again, and the extreme spreads went from a low of 16fps for 6 shots, to over 100fps for 15 shots, most were in the 35-50 fps for es???

I'm really losing this battle. I have the hammer screw all the way in, and running it on 5, 6&7. with velocity in the 845fps for setting 5, 880fps for 6 and 900 for 7. I know it's not tuned, but my Impact was very tolerant of being de-tuned. It would be way off tune and shoot a string with an es of 4fps.

When I get time, I'm going to pull the liner and put a different one in. I have another liner for my Crown, that I know shoots very good. The liner in there now, when clean and I push a pellet through it, it is tight at the breech, then very loose in the middle, then of course the choke is tight. My Crown liner seems very consistent until you hit the choke, obviously. We shall see.

Also, next up is to remove the hammer and clean and make sure it's dry and not hanging up on anything.

I ordered a regular pellet probe, so we'll see what that does.

I checked the probe alignment, but a pin probe would seem to be more forgiving in that there is no hole to line up, you simply are ok if it is in far enough to seal on the barrel's breech oring, correct?

I will try the tune, when and if I can get the strange spreads below say 50-60 fps. With the wild spreads I'm getting, there doesn't seem to be much use in trying to tune. I mean, I've had two Impacts, a M3 and an M2 (X), and I had three or four Dreamlines, still have one, and I have a Crown, they are easy as all get out to tune. Heck most of the time, they shoot a bad tune well. Go firgure?

I'm using the standard 11.4gr hammer. HOWEVER, the previous owner had a Huma power tune hammer etc in the gun. I'm wondering if it has the extra power srping in it and that is simply overpowering the whole thing. Still it seems at minimum that it would still shoot more consistent that I'm seeing. I measured the spring and it is 56mm long, 1.4mm wire, 9.87 od and 6.96 id.
