Title: 600mm vs. 700mm for target
Post by: EPG8 on April 23, 2021, 03:28:47 PM

Considering an FX Impact .22 for target bench shooting. Would you choose 600mm or 700mm barrel for target? I’m thinking the 600mm barrel would have less flex and therefore might have an edge in consistency/ accuracy... but I’m hoping to get some advice from the experts here.

You'll just be able to increase velocity ~ 30 to 40 FPS is all with the 700mm.  Maybe just a little less of a harmonics fight with the 600mm. The efficiency won't quite be as good with 600mm verses the 700mm for the same velocities, but who cares with a bottle gun and a compressor to fill.  I chose 600mm for my .25 cal for the length and 700mm for my .30 cal for max power.  Both are lasers with high shot counts (580cc bottle).
