So I have decided finally on an Impact. Now I’m torn between 25 or 30 cal. Mostly will be doing hunting. Squirrels, birds, raccoons, nutria. Any advice is helpful.
25 or 30 Cal
- Thread starter Zeringue
- Start date
I have never owned a 30, but the 25 will take care of any of those animals on your list with less air and a bigger selection of pellets

I have both calibers for my Impact. I have the .25 in 600mm for nice strolls through the woods tuned at 70 FPE. The .30 in 700mm for increased power at 100 FPE for bigger game. For what you want to shoot, the .25 in 600mm or 700mm shooting slugs will be a breeze setup correctly, especially since the Impact is a fancy laser pointer with a big bite to it. It can also be powered down with a simple turn of the power wheel.
To add more, I recently popped a coon with the .25 cal. You'd of thought I hit him with the .30 cal it was so devastating to the critter.

What slugs are you shooting with you impact. If I tune for 36 nsa. And install the slug pin probe. Can I let’s say shoot 33 jsb with out having to readjust the pin probe.

I recommend the .30 cal. Impact hands down over the .25 cal...that said, I recommend you replace the pellet liner with a slug liner which will allow you to shoot your pellets accurately at much higher velocity than the pellet liner will and also slugs of course. The 44.75 grain pellets should give you better accuracy than the 50 grainers. As for slugs I have found two that are extremely accurate out of my slug liner...the NSA 49.5 grain and also the NSA 61.5 grain hollow points. (Both will work in your High Capacity Magazine).
I get best accuracy with the 49.5's at 1010 ft./s, and at 960 ft./s with the 61.5 grainers. I shoot the 44.75 pellets at 1040 ft./s for best accuracy. Shooting these projectiles at those velocities will give you 3/8" to 1/2" groups out to 50-60 yards...and should provide all the accuracy and power you need for small game hunting. And your .30 cal. Impact will do this with out even breathing hard...it is a power house!

Original slug a liner from a year ago. Regulator set at 150 bar. If I remember correctly I think I'm getting about 42 shots on a 250 bar fill. Plenty of shots for just about any small game hunting I can think of.

That’s not bad. You still have the 480cc bottle. Or did you switch to the 580cc? Are you running a dual TP and pin probe or the modified style from huma with the larger opening?

I have the .25 700mm slug A liner and a 30 cal 600 STX. I have had my 30 cal liner for six months and it has never even been on my gun as yet. The .25 shoots the NSA 36.2 slugs great even out past 200 yards.

I would be more comfortable shooting a 30 caliber FX Impact straight out of the box/case with 44gr JSBs for racoons.

I have always been a 25 cal guy. That’s all I shoot. I have so much 25 cal ammo which is why I’m really leaning towards a 25 cal. But the 30 cal is just so tempting!

30 caliber without question. The only advantages the 25 offers over the 30 is cost of ammo and quantity received.
The 30 caliber hole,smack and power down range is very gratifying.

.22, slug A liner, a lot of slug options and shoots all of them amazing, mine currently is shooting 30gr slug@1000fps, I've been shooting pigeons and ground squirrels out to 240yds with ease

I agree with this. Raccoons are tough. You can kill them (obviously) with a.25, and even a .22, but virtually perfect shot placement is absolutely essential. The 44gr JSBs from a .30 Impact just carries a lot more energy!
