Choosing The Correct Pellet

[Miikee-L 72]

Hi lads!

 

After finally getting my first PCP (BSA Scorpion SE .177) i have been getting to know the gun as well as possible! i was told to put around 500 pellets through before starting to try out different pellets as this would lead the barrel. To do this i set up a target in my garden that i have just measured it to be 21 yards.

 

So after putting through a tin of AA Field 4.52 this is the sort of 10 shot groups i was getting

 

 

However i have put through about 40 JSB Exact 4.53 and these have tightened the group right up

 

 

On the target cards you will notice that i put 15 yards, thats my estimate (this is why I'm saving up for a range finder! ) but i have measured it since and found out that it was actually 21 yards!

 

I know i will have to try them out at further ranges to be sure of the pellet but as my last gun was nothing more than something i used for hitting cans and stuff, not taking it seriously, I'm just getting used to using a deadly accurate piece of kit of which I'm still amazed at the accuracy I'm achieving and when I'm comfortable i will hope to be out hunting!

The exacts look good.

You should try some crosman accupels or premiers - BSA barrels seem to like crosman pellets I've found. Both the scorpions I have like them.

The safest part of my garden I can shoot in is only 16 yards long and rested shots using crosman premiers go through the same ragged hole with both my scorpions. On my permission at 35 yards, the range I zero at, they're shooting clover leaf groups providing I pay my part so I would recommend you to test some against the exacts at longer distances. But barrels are strange things and each one, even on the same model of gun, is unique but I'd say they're definitely worth a try.

Nice grouping, I use air arm and get a group like that at 45 yards,You cant go wrong with them

Also try some RWS superfeilds they are good for the price and like BSA barrels.

Cheers lads i will pop out and get some when i have time! as i have only tried two pellets and not at a very long distance ether.

 

What would people suggest is the correct distance for finding the right pellet? about 35 yards?

You've done the right thing in my view. Starting with aa fields, which look deadly, then experimenting. Again, you're right in moving back to confirm and clarify.

 

Good job so far, good luck and happy hunting!

Oh and thirty five yards is generally ok for .177 but downloading chairgun will help in deciding your optimum zero range.

Thanks mate downloading it now!

 

and yes i definitely want to know my gun and distances a lot better before i start shooting live vermin!

Hi

this is from the BSA forum a post made by Tench a very knowledgeable person on airguns

 

i found that the BSA barrel rarely needs cleaning at all, some other makes of barrel go off after a few hundred shots, a good pull through gets them accurate again but the BSA barrel with the JSB heavies never went off.
The ft/lb advantage they have is huge too, at 50 ish yards they will have 1.5 ft/lb more than the lighter ones, its like tuning your gun!
The pellets wide waisted design is the key feature, this places more of its mass away from the centre of rotation, this produces more flywheel effect so the pellet maintains more spin out to greater ranges. With more spin they have more gyroscopic stability which is why they resist the wind.
I have tried them in faster twist barrels but they dont work as well as they do in the BSA barrel, you can spin a pellet too fast, then it suffers the Magnus effect, Google it, i could write pages on it, i have been studying pellet weights and barrel twist rates for the past year!
In my opinion you wont find a more stable pellet with the energy retention of the JSB heavy for the BSA barrel in .177.

 

I all so use these pellets in my R10 and ultra .177 , Daystate heavies are the same pellet

Thanks for the post mate

 

Might have to try the pellet swap on here because its starting to sound expensive haha! Hopefully tho all will be worth it!

These pellets are very good in HW100kt.177 as well

[smoothfinish 26]

Super dome work very well in the bsa have a try with them and im sure you will like them

Will do mate going to pop to my local gun shop and see what they have and get a couple tins of different pellets. Cheers for the advice!
