    Ballistic apps and potential energy via gravity

    I use Strelok and like it a lot, but since getting into ELR, I’ve been trying to get as precise as possible with my POI predictions. Strelok has a few mathematical issues that introduce small errors in the ELR predictions. There is one that I’m encountering lately. And it is present in other...

    600yds today

    I spent the day with my friend at his 200 acre ranch in the Cambria hills, setting up a 25”x23”x0.5” steel plate target at 600yds with a hit indicator light. We used my 7mm and 308 builds to shoot. I guess the steel plate was too heavy as we rarely saw a hit indicated with the 105gr 7mm, but...

    AAFTA GP course optimization

    For many shooting in the AAFTA GP circuit, the goal is to maximize their number of GP points. Some likely will decide to attend a specific GP match on whether they think that they can improve their GP score. Under the current GP points rules, it’s possible to unknowingly put your constituency at...

    Fun day shooting ELR airguns

    We were blessed with good weather yesterday, as Rod Java made an early morning trip from San Francisco to meet me at the SLOSA range Smallbore clubhouse. The adjacent ranges were busy, which limited our down range access to set targets. But we had an electronic indicator on a 223yd target and we...

    Small issues with Strelok (and ChairGun Elite)

    Something to be aware of when using Strelok. It can cause you to be off by a click or two at certain distances, especially with low velocity projectiles. Past your zero, Strelok only calculates data in meter increments. So if you are zeroed at 25yds, but want dope for say 35yds vs 36yds, there...

    Athlon 15-60x56, Heras vs Ares

    I plan on shooting in the 2024 WFTF match in Phoenix. I have only used up to 24x scopes in FT up to this point, so decided I better get a higher mag scope with better focus range finding. I had the opportunity to look through both the Heras and Ares 15-60x56 at different times and was impressed...

    Ballistic apps - something missing

    Most ballistic apps have scope location settings for horizontal (X) offset and vertical (Y) offset. They can be set to actual inches of offset if needed. Though I don’t use those, what I would use, but what’s missing is a similar setting for (Z) offset. That would be how far away the scope is...

    Precision ELR shooting vs …

    … a “Hail Mary” shot that happened to hit some kind of target. “The Long Range Club” is a sub forum on the GTA. They welcome all posts about ELR and airguns, but if you want to get any credit for good shooting, the minimum acceptable for a record distance, is a 5 shot group with at least 3...

    2361 yards! A newer WORLD record!

    The newer “world record” is 2361yds that I just did. I’m pretty sure I saw an impact, but It was too far to go take a picture. But I can post a video of me pulling the trigger.

    300yd practice

    In reparation for the 2023 EBR Open big bore match, I shot some 300yd F-class targets for score today. No practice shots. 4 targets, 5 shots at each target. Scores for each target were: 44, 40, 44, 46. For a total of 174 pts. Here is the best of the four targets. I plugged the holes with 7mm...

    RMAC 2023 and ELR

    As of yet, I have not seen any other posts on the Magnum Slug Challenge at the 2023 RMAC match - so here goes. Last year, Dave Wilson got first place shooting my .257 barreled, highly customized Armada. He cleaned the course. So this year, they made the course tougher. This year, there was...

    Preferred scopes

    Years ago, hunters tended to use lower power scopes on airguns. I’m curious what’s common today. What are you using when you hunt with your airgun? 4x32mm? 3-9x40mm? 3-12x44? 4-16x50? Etc.

    First time at 500m (547yds) with an airgun

    On 01/26/2023. My 7mm airgun has been sitting in the case for about a month. The weather had finally cleared up enough to go out to the range again. I made a plan to collect some solid long range data. I prepared 4moa targets that would be placed at 200m (219yds), 300m (329yds), 385m (421yds)...

    1st serious try at 419yd target berm

    Most of the shooting today was at 300m, but I decided to push it out to the 419yd berm and see how the 7mm would hold up. I checked Strelok and I dialed in 73.5moa. I took three shots at a standing turkey silhouette and connected 2 out of 3, knocking it over on the 3rd shot. It is still carrying...

    My new build for ELR

    Actually, a rebuild. I had built a .257 ELR air rifle specifically for the ELR Magnum/Bigbore slug matches such as those at RMAC and EBR. It did great, but new rules at EBR necessitated an upgrade. Also, there have been instances where target distances have started to exceed the 300yds that the...

    Info on another scope brand (Ayin)

    I like Athlon scopes and that's what I have been using lately on a few of my airguns. I have a GEN1 Helos 6-24x50, a GEN2 Helos 6-24x56, and a Ares ETR 4.5-30x56. I like FFP, MOA scopes in the 6-24x50 range and there are lots of options these days. I was looking for a lower cost option to put...

    No strings attached

    This is a about an idea/invention of one of our club members and a friend of mine, John Bergquist. He graciously runs FT matches at his Cambria ranch, usually by invitation, mostly for our local club members. During these Covid years we have been using his course almost exclusively for our...
