    Rifle Scopes Leupold Mark 4HD

    The field of view numbers on the 6-24 relative to it's power range are better than those of the 4.5-18x. Side by side with the two samples I had I thought the resolution of the 6-24x was very slightly better. Realistically, I probably just didn't have it set exactly to 18x but perhaps 19x or...

    New RF bino from Vectronix!!! Vector X

    Yes, the U.S. has class 1M which is a little more powerful than the EU with class 1.

    Barrel Torque Ludicrocity

    Somebody may have answered this in the 4 pages I didn't read but they didn't on the first so I'll provide my understanding of the reason. The reason for very high 100-150 ft lbs of torque on a barrel is not related to the barrel coming loose. It is related to the amount of elastic deformation...

    2025 BigJimFish Review / Article blog: More 350L, Garmin and Athlon Chronos, Leopold Mark 4HD, BurstFire, Field Optics Research, videos and visits

    Update 10-17-2025 A couple weeks ago I got a product announcement e-mail from Grayboe about a new stock called the Core. The geometry looks nice to me and it looks like Grayboe may be using a slightly different molding process from the previous stocks that I reviewed from them such as the...

    New RF bino from Vectronix!!! Vector X

    Well that is very interesting. The vectors I have are pre-production though their optical components are production. The electronics have a slightly different firmware in the fpga and cannot be OTA updated on the unit I have at least. For Fov comparison I was just parroting the company given...

    Xero C1 Pro - v3.30 update

    Very interesting. I have never had 30 sessions on one day. I wonder if it had some next level glitch related to a high number of sessions on the same day to add to the normal difficulty it has transferring a number of sessions all at one time. I did have all 50 possible sessions populated the...

    Xero C1 Pro - v3.30 update

    I have the issue that when synced, the Garmin will typically only upload a couple sessions to the iphone each time it is connected. The workaround I have found for this is that I simply have to disconnect and reconnect a lot of times if I have a bunch of sessions since my last sync. I don't know...

    2025 BigJimFish Review / Article blog: More 350L, Garmin and Athlon Chronos, Leopold Mark 4HD, BurstFire, Field Optics Research, videos and visits

    Update 10-12-2025 The review of the Leupold Mark 4HD 4.5-18x52mm is now up. This review also effectively includes the Mark 4HD 6-24x52mm as well as my buddy purchased one of those at the same time and I did all the mechanical and optical testing on both models. As you can probably guess, I...

    New RF bino from Vectronix!!! Vector X

    I found the glass to be as good as Leica Geovid Pro's. The Vector X is a little better in resolution and has a larger Fov. The Leica has significantly better color. I have not had it side by side with Zeiss's rangefinder. Without question I consider the Vector X to be top tier in glass quality...

    Best Budget/Value Spotting Scope for 600+ Yards?

    Binoculars definitely have the advantage of giving you a far better chance of spotting a missed shot that goes into a non-reactive background such as deep vegetation because you have a far better chance of seeing the bullet or trace all the way to the target. A higher magnification spotter will...

    2025 BigJimFish Review / Article blog: More 350L, Garmin and Athlon Chronos, Leopold Mark 4HD, BurstFire, Field Optics Research, videos and visits

    Yes, I just sent the draft off to Leupold for any comments. I should have the review posted within a week. As with the Mark 5HD, I expect I will be recommending the Mark 4HD series to a lot of scope buyers.

    Calypso AB Mini Ultrasonic Wind Meter

    So... my experience is that the software and firmware for the Calypso mini AB is pretty buggy. One of the bugs I have had is it not wanting to connect and me initially thinking it's bricked. This happened to me after a firmware update with the configurator app used to update the devices...

    2025 BigJimFish Review / Article blog: More 350L, Garmin and Athlon Chronos, Leopold Mark 4HD, BurstFire, Field Optics Research, videos and visits

    Update 9-22-2025 Just posted the written review of the BurstFire Gen2 2-in-1 flame annealer and case prep center. This was a unit I bought partially to dip my toe into annealing and partially because I was looking at few hundred 350L cases that I needed to remove the crimp from to use in the...

    Power trimmer vs Annealer vs Powder Scale

    My thoughts: On the trimmer, I have the Giraud and purchased it before I even did articles and reviews for the industry. At some point I should probably write a review of it. I found trimming so onerous that this was the first powered piece of reloading equipment that I purchased. It is...
