Title: FPS for .177 competitive target shooting
Post by: EPG8 on June 02, 2021, 09:58:37 AM
In your experience, what is the typical velocity (fps) used in .177 benchrest competitions?  Is it in the 700fps range, 800fps?  Just wondering what the best shooters use when striving for ultimate accuracy.

Field Target shooters choose 12 ft/lbs, 820 fps for international.   For US Open class at 20 ft/lbs, 900 fps. I shoot Open at 875 fps. All ammo is JSB 8.4 grain.
I assume these energy levels would also be best for benchrest.

It depends on which class of benchrest you are competing in, there are several classes for .177 caliber. The two I am most familiar with is light varmint = 12fpe and depends on pellet weight to determine fps which is in these ranges, 10.34 grain is 715fps, 8.44 grain is 800 fps and 7.9 grain is 825fps.

Then heavy varmint which is 20fpe or under.

Here is the US benchrest rule book to give you all the info you need for all the classes.

In Field Target there are several Open Class 20 ft/lb competitors that shoot the heavy monster pellets. Thomas rifles seem to do very well with them as recommended by the mfg. He/Mike is a top shooter and has done extensive research on these heavy pellets are great in the wind. His excellent advise and tips are here if you search.

Many of the air rifles intended for 10 meter ISSF competitions (that are very expensive) are pretty low in the feet per second category. 

The FWB 800 for example is less than 600 fps.

I think I read somewhere that 600 fps may be the legal competition limit.  I'll seek confirmation.

You are correct. ISSF regulations for 10M rifle and 10M pistol is 600 fps max.

Yes the limit is 600 fps since any higher fps/fpe will destroy the catch container for the pellets behind the electronic scoring systems. Most guns are set at between 550 and 575 fps from the factories.

I believe the reason for the 600 fps limit is German law.  It is legal for a person over 18 years old in Germany to own a maximum 7.5 Joule (5.53 foot-pound) air rifle without having a purchase authorization (background checks, proof of competency), so I think the development of sub-600 fps target rifles to be related to this law rather than pellet trap or electronic scoring durability.  I think the rifles, traps, and scoring systems were designed with the sub-600 fps legal limit in mind.

You may be right as far as it being German law, but I live 10 minutes from the CMP ( Civilian Marksmanship Program ) south 10 meter range and shoot there often and was told by the head range officer that the 600 fps limit was to prevent the destruction of the catch traps behind the electronic scoring target system they use at the range .

So both are likely true.
