About NSA 33.5grain slug

Dear Airgunners,

Anyone who shot NSA .25, 33.5 grain slug with FX slug line A barrel? what is the recommended speed for the best accuracy? i am planning to buy some NAS slugs and wondering what velocity i should tune my Impact..

Regards

I find they shoot very well at several velocities from 740fps to near 920fps from my 700mm slug liner. Best BC is low 900's though so I try to keep it near there. Two of these targets were shot at 740fps one at near 920fps.

All shots at 100 yards.

NSA 33.5gr HP bottom right was a sighter I was shooting six inches low and to the right.

VK 34gr HP

NSA 36gr dimple nose I was unable to see the bottom three shots through my scope so I raised the elevation and shot the next three shots. ;^)

Great, and thanks to Bio,

I will try the speed you mentioned, 36gr looks better than 33.5gr from your shooting,and VK too, maybe i should buy two of them and test,^_^

For all intents and purposes the groups are pretty much equal. I shot a tiny group with each of the other slugs too but they are not the norm. The norm is half to one inch with little to no wind. More recent shooting has the VK34's and the NSA 33.5HPs out shooting the 36 dimple nose slugs cuz I often get a flier with the dimple nose slugs for some reason. I have yet to shoot some heavier Hollow points and expect them to do well although it's hard to beat what I am shooting now. I plink at spray paint cans at 200 yards and hit them about half the time. But the wind is usually a factor and I am usually holding a foot or two for it at 200 yards.

Thanks, Bio for the update, I am going to test H&N slug with dimple nose and 33.5HPs, let's see how they work.
