My Crosman 760 MSP ... Daisy Zinc-Coated BBs and Avanti Precision Ground BBs



Log in to see fewer ads
I spent sometime this afternoon after work shooting my 760.
The object was to refine my 21-foot zero with the open-sights.
The 760 front sight is relatively wide.
As such, I was using the "pumpkin on a post" sight picture at 21-feet
with 3-strokes of compression.

This translated to "post on the middle of the pumpkin at 10-meters.
When I decided to try my luck at a longer range.
I added 2-stokes more compression for a total of 5-strokes of air charge.
This is one reason I like multi-stroke pneumatics.
As range increases ... it is easy to compensate by adding more strokes of
compression.

I've been using Daisy zinc-coated BBs exclusively in my 760.
After doing some research on BBs, I concluded the Daisy zinc-coated BBs were
reasonably accurate.
More so than Crosman BBs.

However, I'm gonna try-out some Daisy Avanti Precision Ground BBs in the near
future.
This change will ... no doubt ... require re-sighting-in my 760.
Which is gonna be a real pain because of the lack of windage adjustment.
To shift right or left, I must use some pliers to "pull" the rear sight blade.
This is a hit-or-miss proposition.

Daisy Zinc-Coated Bulk BBs
This is a typical pecan that I was using as my POA.
I was consistantly hitting high and too the right of POA.
It took me quite a while to set zero because of the springiness of the rear
sight blade steel.

POA - Center Mass of Pecan
POI - High to the Right
After taking 5-shots, I went down-range to see how far-off the POI was from my POA.
I was very surprised and pleased with the size of the group that was formed.
Can I duplicate this group ... again?
Well, I gonna try with the Avanti Precision Ground BBs and see if the Avanti's perform better.

5-Shots, 5-Strokes Compression at 15-Yards with Avanti Precision Ground BBs

Late this afternoon, I decided to try-out some Daisy Avanti Precision Ground BBs in my 760.
It wasn't easy ... I had to fire-off several groups to warm-up.
This is the best group of the shooting session.

As predicted, the Avantis are not striking at the same POI as the Daisy Zinc-coated regular ammo.
I can't explain why ... but, the POI is different.

Judging from the performance of the Avanti BBs ... I gonna have to transition the 760 exclusively
to precision ground ammo.
The additional cost of precision ground BBs is a trade-off I can live-with.
After-all, life is too short to me to tolerate less-than-the-best ... if you can afford it.
And, BBs aren't that expensive. LOL

It is evident to me my Crosman 760 deserves a set of better iron sights.
To this end, I'm thinking of installing a set of peep sights.

Your gun is liking the Avantis!

Below shows how I converted one of my Red Ryders to have a fully adjustable rear sight, might be something you could do. All this takes is the blade and screw
from a donor (or make the blade- this would be a good DIY project) and a little fitting of the parts. I robbed the sight blade from a Daisy 74, but what gun doesn't
matter as long as the parts are similar. The top edge of the original sight was ground down even with the bottom of the sight notch, then I used an auto center punch
to locate the hole, then it was drilled and tapped for a 4-40 machine screw.

About the only downside is adjusting the windage requires a screwdriver. But once it was dialed in, elevation changes were all I needed to keep on target.

Peep Sight

Yes, sometime ago, I saw a thread depicting the same project.
Good idea ... even better would be a peep-sight like the type
mounted on the Daisy Model 25.

Practical Accuracy With Open Sights

With open-sights, this is the best accuracy I can manage with my 760.
For my purposes, this is good-enough.
By the photos, the Avanti Precison Ground BBs have a slight edge-on accuracy over the Diasy Bulk Zinc-Coated BBs.

On-the-range, while engaging the same targets ... one-inch pecans ... under the same environmental conditions
and with the same shooter.
I find that I experiance fewer-misses at 10-meters to 15-yards when shooting-with the Avanti Precision Ground ammo.
However, from 15-feet to 25-feet I can't say there's sufficient difference in accuracy for me to take notice of.

And, while trying to smack pecans out to 15-yards ... at that distance, the best I'm hitting is 3-out-of-5 shots on average.
But, with 3-strokes of compression at 25-feet and under a 4-stroke charge for 10-meters shooting ... the 760 is in its element.
And, so am I.

The Crosman 760 trigger is an integral-part of the satisfactory-accuracy I'm achieving.
The trigger is a moderate-travel single-stage, that exhibits a very slight hit of creep just at the beginning of travel.
However, there isn't any associated grittiness.
While definitely not light, the trigger certainly not heavy and transmits some stacking as the end of travel nears.

Let-off is ... refreshingly for a Crosman ... not vague.
Just as the trigger continues to stack ... and, you start to think ... that's more than enough resistance.
And, there's no doubting the trigger feed-back ... then, as your trigger-finger is about to chime-in "that's way too much"
- the sear slides-off.
Thankfully, sending the BB down-range.

As such, let-off can be anticipated and reasonably clean.
Although, not quite crisp - smooth is what comes to mind.
All-in-all, a good, safe and serviceable hunting trigger - for kids.
But still, adequately workable for an adult.
