Marauder Benjamin Gen3 - It Just Works and Works Well

I was referring to the 250z, sorry LOL. The last thing I did with the Marauder prior to removing the stock was move the target back to 75yds. Unfortunately with the JSB 18.3gr pellets the groups really opened up. The Apolo slugs did good at 50yds. I need to finish the stock and then try some others. I’ve spent most of my time working on the GSX-CS4. The Walmart NSA did terrible in the Marauder. They have 216 in the part number, makes me think they are too loose.

Hey Bill, the JSB are 18.13gr the last time I checked, lol. Unless they did change them, it's been so long since I bought any, they might have.

Well, I have a super accurate digital scale that I paid $20 for and my JSBs are 18.13gr. Or I was giving them the same status as my coveted 18.3gr AEAs, take your pick.

I guess I’ll spend Labor Day editing all of my 18.3gr JSB posts lol.

Some people might jump all over me for saying this, because I don't compete, but I do dispassionately read all their results and can see trends w/o any emotional baggage, and the only two pellets worth shooting at high speeds in a .22 are the JSB MRD (w/flyers and all) and the AEA 21.9. If you've got some old MRD's, those all day long. I absolutely love the 18.13 JSB pellets, and they can shoot well fast sometimes, but they will lose it where the other two won't. If you shoot a 18.13 between 850-900 it won't give you any surprises as you move out. I shoot my spinners at a 100y quite regularly, using them. Yeah, there's more drop and drift, but that is easily figured for, and they are my number one choice for plinking. Seeing as you are mostly going for benchrest I think that you would be better off just sticking with shooting the AEA and getting used to those, at least until/if the MRD's get back on track.
