Yes, I probably use a "random" rest since I get random results. I definitely don't use a "ransom" rest.Can’t remember. Are you using a random rest?

I asked because your groups are remarkably good. I’ve shot maybe one group like that in my life but you seem to be able to do it consistentlyYes, I probably use a "random" rest since I get random results. I definitely don't use a "ransom" rest.
Thanks for the compliment, I do appreciate it.I asked because your groups are remarkably good. I’ve shot maybe one group like that in my life but you seem to be able to do it consistently
IMI Defense for $28 - https://www.amazon.com/IMI-Defense-Polymer-Scope-IMI-ZPM01BLACK/dp/B0C9TLNQNB/ref=sr_1_1Is that a rail mounted scope? Who makes that mount?Ah, a scope! Interesting.
do you have to allow for parallax on that scope setup?Thanks for the compliment, I do appreciate it.
This is basically what I use. A foldup table, with an MTM rest. The back part where your hands go is not very good, so I use one or two small towels for my hands to rest on. The hand rest is one area I need to try and improve upon. To the left is the P220 I used in the test with the mounted scope.

The parallax is not adjustable and it is set for 50 yards. So at 15 yards I just need to try and line up exactly the same way every time. It is not perfect, but still way better than the alternative of using open sights to test my loads.do you have to allow for parallax on that scope setup?

I also use the IMI defense scope mount. It seems to work well on the sig proprietary rail, a very tight fit. It is actually made for the picatinny rail, but is not as tight a fit. My SIG SP2022 has a picatinny rail, but I think the scope moves since I never see very accurate results. The live life writeup is excellent in describing the issues with the scope mounts.Is that a rail mounted scope? Who makes that mount? Thanks for all the load work up work. My P220 is an older German Elite and has combat night sights - I’d probably get touching holes on paper if I sent 50 down range.
have you tried moving the scope closer, or farther away, as to create that dark fuzzy ring around the crosshairs? that may help you better align your eyeball with the scope axis.The parallax is not adjustable and it is set for 50 yards.

Thanks for the advise. I think the length is just outside when the fuzzy ring disappears, so it is probably the same every time. I try not to change position once I start with the 5 rounds, and I basically line up, and pull the trigger. I don't spend much time trying to be precise at when I do this testing. With the follow up round I normally take more time and try to be more precise.have you tried moving the scope closer, or farther away, as to create that dark fuzzy ring around the crosshairs? that may help you better align your eyeball with the scope axis.

Thanks for the advise.Yep, an old trick.
Use a Diamond shape target to help align the cross airs. I use these when I have a scope with the heavy lines. Just gives you another reference on alignment.
probably not worth a new scope to solve the parallax issue [if there even is an issue].
@Blue68f100 reminded me of another trick: put up a square bulled target and set the lower left corner of the square against the upper right quadrant of the crosshair. leave a sliver of white between the two. this works great when testing a load using a scope with thick crosshairs.

Thanks for sharing. That looks like a good solid setup. It seems these single magnification lightweight scopes are more difficult to get. eBay is probably a good place to look for them.I don't know what yardage this scope's parallax is set at, but I'm sure it's short.
I bought it with the scope attached, factory rear sight was included.
It's a little Bushnell Phantom II 1.3X.

I don't doubt it. Brrrr.Reloading testing life is tough in the Pacific North West this time of the year.
