DavecUK which dosing funnel do you have? Is it an ‘inny’ or an ‘outy’?
I’m finding it’s quite a well debated topic that some feel the ‘inny’ versions create channelling issues, but the counter argument is that the inner rim doesn’t penetrate deeply enough to cause the effect. I’ve kind of concluded that spending £2500 on my set up is justification in itself to buy a dosing funnel that doesn’t sit inside the rim. I’ve seen some nice walnut versions on etsy for around £30 and if course there is the ‘decent’ funnel, but I’m struggling for other options to consider.
