Is it too late to cancel your order? A Remington 870 Compact 20 gauge with a 21” barrel and an Indian Creek .555 choke with 1 5/8oz of #9s will give you around 300 pellets in a 10” circle at 40 yards. 👍
I couldn’t get the more open chokes to throw a pattern that I liked. I went .555 in my 20ga and .660 in my 12ga for my preferred pattern. You just never know until you shoot them.
I use 870 and 1187 in 20 gauge both with 21” barrels. With my handloads I’m getting 300 pellets with my 870 and 350 pellets with my 1187 in a 10” circle at 40 yards. I have Vortex Venom 3 moa red dots on my turkey guns.
StaBall 6.5 powder, 143 grain eld-x bullets for practice and some with 140 grain Accubond bullets hunting loads with Fed210 primers in all. Nosler brass
I use a RCBS hand primer and love it. I’m not sure what another priming tool would/could do that the RCBS one that I have can’t.
What problems are you having with your RCBS priming tool?
