Don't make the age old mistake of putting a few through the barrel and deciding they are not working in that barrel - I would only test them properly after putting a considerable amount through the gun .
Sort , weigh , size , same batch ............. good luck . lol
I always thought 451's were perfect in my guns until I tried 452's on paper , the difference was amazing and I must have scraped through on a few splitters in the past when using 451's I know that !!!!
