Taipan Veteran Long .25 + Question 2-nd

Hi friends again,
For Taipan Veteran Long .25:

1. Has someone with Taipan .25 tested the lead-free pellets? I think they are too too light ?!

2. Which pellets are you satisfied with as 100 yards accuracy:
1. JSB Diabolo Exact King cal .25 25.39 gr;
2. JSB Diabolo Exact King Heavy .25 33.95 gr;
3. JSB Diabolo Exact King Heavy .25 MK2 33.95 gr.

...and 4. Slugs?

3. LW polygonal for Taipan Veteran Long .25?

3. Has anyone tried to make a gun belt at one point as Aaron made his rifles in his YouTube videos? Does anybody use a belt of the Taipan Veteran at all?

Thanks in advance! Greetings.
 
Thanks for the answers. I got from the lead-free pellets of JSB. I bought them before the rifle and they probably will not do the job ... but for my statistics I will try them.

Belt at one point of stock on the rifle? Later I think I should try.

Any tips for pellets of other brands you're happy with? H&N, RWS, Samyang, FX or others?

Naturally, I know that JSB is best but I still have no experience with Taipan Veteran (.25) unlike you.

Something else - has anyone tried to drill holes in the gun shuffle (venting) like Hadjimoto doing on his Evanix?

Also, do you think there is a need to make a barrel crowning (LW)?

Greetings.
