With my chrono on the fritz would anyone like to take a stab at my velocity?

Rem 788, 222 rem and 24" barrel
NOE copy of saeco #221 - 63 gr. checked and lubed
20 gr. imr 4895 - no dacron
Speer 223 brass formed and trimmed to 1.718"
Win srp
Tac lube
alloy is 50/50 coww/pure with about 1% tin and a touch of copper, water dropped

I shot three 5-shot groups this morning, two at 100 and one at 200. The first group @ 100 was four in 7/8" with one out about 3", the flier was the second shot. The second group was under 1 1/8", horizontal.

The 200 yard group is shown.

81383

A drop of 5 1/2" with a 100 yard zero isn't matching with what I think I should be getting from a velocity standpoint. I did have about a 3-4 mph breeze coming over my right shoulder going about 11:00.

And yes, I am pumped. I have been working on this rifle for almost 4 years. Every little thing matters.

Thanks to all

Darrell

Based on 60 gr cast over H4895 in a M788 i'd say 2000 +/-.....more than likely +.

I would guess about 2600 fps, maybe 2700! Just a WAG! The 22 cals are fun aren't they?

Low lead waste low powder use. I like using my 222.
