Interesting 100yd Group with NSA .177 slugs

[Guest]

This group of ten rounds was shot at 100yd this morning. The winds were right to left, 3-7mph. I did not wait for the wind to die or be consistent as I wanted to see what sort of drift/spread would occur. Sorry the poa is not in the picture, it was about a foot above the group. The 8 shots on the right are about 3.5" outside to outside. The two on the left open it up to about 5". For me this shows great potential in the round at that range. The next chance I have to shoot there I will set up a couple wind flags and see if I can get MOA groupings or better.

What rifle were you using?

 

[Guest]

Air Arms S500, regulated, tuned. Spits em out at 710-715fps.

Can you tell us what Gr. Slug & what twist rate your barrel is? I’m very interested in shooting these myself, but think my twist may be to slow? Or I’ll have to bump up velocity to point of deminishing return on accuracy?

 

[Guest]

they are 15.5g. It's the only .177 they make. As for twist rate I'm not sure, it's somewhere between 16-18:1. I don't know if AA has their barrels made to their specs of if they are off the shelf. I have no plans on increasing velocity at this time as it is working very well at the speed it's shooting.

Very impressive 10 at 100 with .177, look out pests.

Thanks. While I did remove a squirrels brain through it's mouth the other day(if they stay in the woods or tree's I don't mind, but once in the yard they are given no quarter) that's not the main plan. A trip to the EBR may be in order. Not this year though, FT Nationals is the same weekend.

John, we need to go shooting some time.. I’ll bring the war! I bet if you pushed those 900 they would tighten up!

Thanks. I'll not be touching this guns tune again unless something fails. That's less than likely as I rebuilt and resealed it this winter. I may have to buy a used one later on to test different speeds though. There will be an outdoor BR match next month in Lebanon Ct if you're interested. The details are in the competition section.

Your Groupings are pretty tight. for a .177. I shot them out to 55 yards not bad groups but not as accurate as the pellets. The thing thou is with wind it will out perform pellets in the right conditions. 

I might try posting some photos of 55 yards with the slugs. Curious what your groupings are at a closer range say 50 meters ect ?

 

[Guest]

This is a 50yd test between them and pellets.

The tighter groups for each round were shot during calmer, but not windless conditions that day.

They definitely have great accuracy potential especially for being a hollowpoint,great shooting!!!

Thank you. I'm itching to see what I can learn and do with a few hours at 100yd. I'll have a more relaxed approach and choose my shots with more scrutiny. Like I said itching to get out there.
