I have a new Mora in 25 cal which I purchased from Talon. Two questions. My shroud, at the rearmost end, is fitted to the clamping collet with four screws to secure it to the barrel. I have read the technique to put the shroud into compression but this end piece has two O-rings &, as I tighten...

Sorry, just saw title 🙃

For which barrel?

Well deserved…

I like the metaphor of pole vaulting but let’s postpone, at least for awhile, the question of what we are vaulting over…

I may be splitting hairs here but I imagine a swaged slug (Corbin) to be like a second generation version of a CNC turned slug (Altaros). Altaros seem to claim as much… But, to go back to the original post, why no public numbers on run-out? Berger claims better than 0.0001” and Litz has made...

My current “adventure” is to look at everything in the way of, or perhaps not considered, in configuring a 30 cal slug pcp to become a full- fledged competitor to rim fire rifles in the world of subsonic shooting. This means ¼ MOA @ 100 yds and at least 1/2MOA at 200.

Yes, this is the way most run-out is measured (using an indicator which measures the change in radius as the object is rotated). Sinclair & Hornady both make run-out gauges, I think.

Not exactly. While in the barrel, the projectile follows the form of the barrel (which may help correct a deformed pellet skirt), but when it leaves, it will spin around its center of gravity…. An out-of-round projectile will increase dispersion.

I have been reading the three volumes of Bryan Litz’s Applied Ballistics and feel like I just discovered a treasure trove of information. I am interested particularly in the effect of “out of roundness” on dispersion at longer shooting distances. Does anyone publish the “tir” (Total Indicated...

Which has the better concentricity: a swaged slug or a CNC turned slug?

The Skout Airguns Epoch / Evo has an open - faceted magazine design which uses a relatively short torsional spring to index the magazine after the bullet probe is retracted from the rifle chamber. Because the magazine capacity is higher than average and the spring is unloaded to begin with, this...

What do you think the recoil will be like on the new version? Will it come with a threaded barrel? if so, what are the thread specs?

I know; maybe Optics Planet is expressing sour grapes… I do see the price has come down considerably (at least at Utah Airguns), and there has not been a firmware update for awhile…

There are indications the FX True Ballistics Chronograph has been discontinued, as reported by Optics Planet & AI searches. This surprises me. Although expensive, it got good reviews & provided more information (BC’s) than other chronographs. I am very happy w/mine…
