Hornady Critical Defense 165gr and Winchester 175gr Silvertips

[Panzer]

What are you guys running for springs? I find it hard to believe something in my Witness makes it put up better results than Glocks except if they aren't up to the task from jump (too weak spring). Tuesday or Wednesday I hope to have some answers to these questions.

Mine I guess will be stock, going to order the G20sf and I don't think I can order it with heavier recoil springs from the factory, please correct me if I am wrong on that.

If it is the case, I will see what you data shows and get an after market spring.

Not to make light of your work or opinion, but even from the 6" barrel the Silvertips fail to meet their published velocity of 1290 from a 5" barrel, it got close enought to not complain with your long barrel, but again way off with your 5.5" even.

I still have some faith in the Silvertip load, but it is a bit faded at the moment.

Panzer,
No offence, taken at all!

I fired one or two shots per barrel, with the first shot going 1250 from a stock 4.7" barrel is actually, very close to the advertising... Which BTW is 1280 fps from a 5.5" barrel. I only got 1233 from the 5.5 and 1256 from the 6"... obvious to me simply slow bullets.

If you have ever used a chronograph, you will see differences in velocity, usually a shooter will take a average of all shots fired, the more shots the better the average or the better the realistic average is. My testing is not really "fair" as I feel I simply got some slow rounds. BUT there are sometines barrels that simply do not get top vel out of too...

This was first time shooting the silvertips form the glock. It was also first time using the Go-Pro camera... Both will be better next time out.

No chrony experience here, it is interesting you got more velocity from the 4.7 than the longer barrels, or am I misunderstanding your statement?

[cwlongshot]

Nope, you got it rite. (I think)

The short barrel is stock and different rifling. Its very possible that vel will be different.

Factory bullets are not all that consistent... so it goes that velocity will also not be consistent.  Hand loads, carefully produced hand loads WILL be much more consistent.
