Which is best for long range accuracy?

[idoc]

I shoot NRL 22 with a custom 22lr but have a notion to give it a try with an air rifle. So the rules say you can shoot .22 snd.25 with slugs (or pellets) but .30 with pellets only. If you wanted the best accuracy for 100 to 300 yards which would you pick, the smaller and lighter .22 slugs with better BC than pellets, slightly heavier .25 slugs or the larger .30 pellets? Yes, I know the NRL stages are only up to 100 yards but the local stages can be up to 300.

I think most will say 25cal slugs, 34grains or higher, at 920fps or higher. 

 

[Impact701]

I agree !

 

[biohazardman]

I would go with the .25 with heavier slugs. I shoot the NSA 36.2s from my Impact with a 700mm slug A liner and they shoot very well at 200 yards. I have not tried them at 300 yards

Thanks all! Biohazardman, are you getting anywhere close to MOA at 200yds?

 

[Raider03]

What airgun do you plan on using. That might be worth getting feedback on.

200 with an airgun? Try 100 realistically. With some slugs you can have more distance. I can't speak for @Biohazardman but in general 125 yards and under is more in the airgun arena. Most people have a very hard time getting 1" groups at 100. It takes practice and skill, which is something some guys achieve with ease here with their skill level. But it isnt as easy as 22lr is my point I guess

I was thinking about trying the FX Maverick with a slug kit. I get that it probably won't be as accurate as my 22lr but air guns are getting so much better at longer distances that the challenge of trying to approach that accuracy is intriguing.

You are likely to get better results if you can find either unregulated guns such as Sumatra or Career II 707 both long versions or Air Force Texan 257.

257 Texan I agree.

Thanks for the suggestions but single load guns won't work in NRL 22. Need a 10 shot repeater as you only have at most 120 seconds per round and you are often moving from one crazy position to another. Plus, at least for me, it needs to be relatively light weight since I can't lug my fat ass plus a heavy gun around.

Slugs in certain guns will shoot sub moa out to 190 yards. I did it with 2 this past week. Fx may need slugs going 900fps or better but that’s not the case with other barrels.

Just wondering what twist barrels are best with the slugs in .25 cal.?

 

[idoc]

The FX superior heavy 0.25 cal twist rate is 1:18 vs 1:24 in the STX pellet barrel.

The AGT Uragan 25 cal has a 17 twist and shoots slugs pretty good. 

 

[Stretch]

I'm sticking with .22 cal and tuning for H&N 25 grain slugs (0.1 BC) in one rifle and FX Hybrid 22 grain slugs (0.08 BC) in the other.

Rifled or polygonal for slugs? 

 

[Nsboost]

22 is the BC king…. BUT… you get more air efficiency out of a 25 from my experience… so .25 is my go to.

 

[rappert]

My .30 cal is my most accurate gun in the 100-300 yard distances. With very low wind I got this group.

I agree

Would both of you, Nsboost and Georgeppn, explain to me with a concrete example what you mean by that? Thanks.

Because....
Internal ballistics so far has been like the classes in physical science I took in highschool... —
▪︎I attended...
▪︎I pretended to understand...
▪︎I received a categorization "dumb as a rock"...
▪︎I received an evaluation "D" — with an 80% chance of an "F" the following year.
