    Theoretical Groups at Distance

    My simple mind says that: 1. You can prove it mathematically with pythagorean theorem and similar triangles 2. Or swag it. If 40' is a 1" group then divide by 8 to get 5 yard change. 35' is 7/8" 45' is 1 1/8" That is my 15 minute thought pattern.

    What did you do airgun related today.

    We finished up on my wheelchair rifle mount today. Will test it with the Hammerli 850 and ATN Gen 4 cast to my phone Monday.

    What a BREECH!

    A 380 grain slug out of a SA could be used for thinning feral hogs. I would think 6 down would be doable on average with a large herd.

    Need help for a PCP

    The Air Arms S510 walnut is 1/2 pound lighter than the HW97K. If your willing to go tactical the weight drops from 8.37 to 6.75 lbs. Utah Airguns have open box. 22 tacticals $800 less than PA. https://utahairguns.com/product/air-arms-s510-xs-22-tactical-airgun-open-box/

    N/A Ok serious off the wall question

    If I had unlimited money I'd buy the people who better understand how current airguns work, and how to improve them. I'd have them start with .20 caliber. @Motorhead @thammer etc I'd fund aerodynamic/external and internal ballistic work and creation of pellet dies for the new barrel with mass...

    HW/Weihrauch HW35E-Great Rifle

    I found a HW35 with the old style stock used at AoA a couple of years after the new style came out. No idea what spring is in it, but the way it shoots I can't understand why anyone got rid of it. I know I never will.

    Airgun Revisions

    I needed a 70 year old Benjamin Franklin rebuilt for a gentleman whose father purchased for him when he was 7 y.o. Rich @Airgun-Revisions did his magic on the rifle while maintaining the patina. Great communication through the process, very timely rebuild, and an awesome price. Thank you, Rich

    Looking to get into the hobby

    I'm in Waco. If you want to put your hands on a few rifles to get the feel for them I have a few. Springers: HW35 and HW50 in 177 open sights Hw97 in 22 scoped PCP: Air Arms 510 in 177 and 22 but no good backstop for them yet so can't fire them. However, can see weight/length of pull. You are...

    A tank question for the HS science & math teachers out there.

    I stand corrected. If you have two 50 c.f. tanks and the guns max fill is 3000 psi and regulator is 1500 psi then: If tank 1 is below 3000 psi but above 1500 psi you can start with this tank to it's max pressure and top the gun with tank 2. My first answer only took into account using two...

    A tank question for the HS science & math teachers out there.

    There is no difference. Twp 50 c.f. tanks will fill the same gun the same ammount of times as a 100 c.f. tank with everything the same. The only variable in the equation is if you are filling the gun from empty the first fill. There is a calculator for tank fills in the Calculator forum

    Tuning General Operational and Math Question

    I sure wish I knew where the Komplete was manufactured. If it was made by Hammerli in Germany with a Walther barrel I'd buy a Inspire Precision air cylinder and a .177 Komplete from Pyramid Air to test. Would be interested in seeing if a $330 air rifle could compete competively in FT...

    Tuning General Operational and Math Question

    I am not being a smart ass with this answer. When I have these type of questions I don't use the AGN search function, but instead use Google to search AGN. Here is your starting search: https://www.google.com/search?q=site%3Aairgunnation.com+barrel+volume+pressure The trick is start your...

    Other thoughts on "tactical" vs traditional rifle

    I grew-up in a time where hunting rifles were wood and most of the collectors were civil war and WW 1 & 2 historians. That makes my tendency lean toward wood. I certainly don't fault others who like tactical for their intended purpose or utility. In all honesty when watching a video where the...

    HW/Weihrauch Stainless HW guys

    I have a Beeman stainless that came with a synthetic stock. The previous owner then traded the synthetic for a nice HW97 wood stock. I much prefer stainless in wood than synthetic. Blued in synthetic like one of my HW30s Makes a great truck gun or a woods walker where the treatment of the...
