.22 cal slug vs .25 cal slug

[6gun]

Like 6gun said, as that wet noodle barrel system gets longer, you have new things you have to address. If you need more than 700mm, maybe just consider grabbing a trusty .22lr.

I've even learned that the power I have is uneccesary. It will go thru a varmints skull, and depending on slug(nsa) goes thru most plywood back stops I put up. It took 2 or 3 hits on the same spot to get get the 1.25 inch cdx at 80 yards. I am the worst at the power chasing bug from airguns to engines. Im just learned to settle down

Yes, just like most things, the law of diminishing returns applies to airguns. But it takes lots of dead animals at various speeds, weights and calibers to start to see the light. God bless the guy who gets a good accurate consistent setting and just makes do with it by adapting. I found it easier just to have several guns because if your seriously anal, no one gun will make you happy for everything.

I’m going for accuracy and precision first then power. I was reading that some guys were having phenomenal accuracy with the .25 cal slugs so I wished I’d went that route

I currently have 2 DRS rifles a 25 700 and a 22 700, they both have slug power kits, carbon fiber barrel sleeves installed on the slug liners, they are equally accurate.
The 25 caliber will easily shoot a 40gr H&N 980fps with the reg @155bar , my 22 only shoots a 40gr H&N 950fps with the reg @170bar.

That's why I shoot the .218 34gr at 985fps with the reg @162bar.

Your Impact should easily do that as mentioned previously.

According to Stelok that is 73ftlbs at the muzzle and retains 55ftlbs at 100 yards

That’s wild. I’m working on tuning mine. Should have saved $100 and not have Utah do it.

So far I’m 930 at 150 bar. I’ll keep working. Do you get more shots on your .25 with it being at a lower reg pressure?

I get about the same number of shots with both guns, 15 to 18 per 230 bar fill

thats not bad. I was hoping for a few more shots like at least one mag maybe 2 mags. idk how many fills i can receive off a 9L 4500 psi tank

also the .25 cal H&N have a higher BC than the .22 cal H&N

You should get way more shots from your Impact, it holds almost twice as much air.

Yes the 25 does have a higher BC, not that much though. You should give the 22 a chance
If you do decide to change caliber, you will need.
.25 Liner lock
.25 Liner
.25 Barrel inlet
.25 magazine I recommend the Orion The Iguana Hunter Magazines.

If you stay with the same length barrel.
You already have the slug probe.

I will give it a chance this weekend. I really liked the power the H&N 25 slugs have. I plan to go to the precision slugs once I’m out of these airmarksman. Pyramyd Air is minutes away so I usually can get slugs next day.
