Dreamline vs Impact

I'm thinking of buying an Impact in .25cal and recently read that there should be a new plenum and barrel band for the Dreamline coming out soon. What are the differences between these two rifles? The only reason I started to consider the Dreamline is due to hearing about the upcoming barrel band. I have read a few posts about the POI changing on the Impact with a slight bump and that does not sound too impressive to me (more like a design flaw as the shroud should be threaded into the receiver). I like to store my rifles barrel up in a locked gun cabinet.
 
Impact does have more power. My dreamline tops out around 50fpe in .25. I've had it to 60fpe with a huma reg and 2mm hammer spring shim, but at half the shot count, it didn't seem worth it.

My dreamline has been really stable though, I've taken it apart multiple times and it is always right on or one or two clicks from zero on re-assemble. Taken it hunting, leaning on trees, etc, and still spot on zero. Not like my marauder...
 
 

Impact for me! I’ve leaned mine against a lot of trees and never missed a squirrel because of it (I’ve missed plenty of them for other reasons)most of the shots I take are inside of 50 yards so the little poi shift hasn’t had a minute of bushy tail affect !

well I must be doing something wrong with my impact, I only need to breath on it a bit heavy and I get zero shift. I had a go at indexing the barrel yesterday. Without even touching the liner, slacken off the barrel nut, tighten back to exactly the same place I was getting 6” poi change ant 25yards.

I have given up on the barrel assembly, both the shroud and barrel nut are going in the bin. The liner is accurate but the constantly chasing zero is driving me crazy, until I get time to make a better engineered solution I am going to fit a LW barrel to the impact.

I have to say something has to be wrong with your gun ! I sat at my bench shot 3 rounds they landed a 1/2”-3/4” high at @50 yards picked my gun up off the bench by the moderator held it like I was going to club something set it back down shot 3 more times and my poi was 3/8” left of where the first 3 were no change in height at all ! Hope you find a remedy for your problem . It is a fun gun to shoot at least for me !

My impact does dime size groups at 85yds and I've got some tuning to go yet. Before you start throwing things in the bin, send them my way...or start a thread on the issue, I'm sure someone can help.

I just put my first slug liner in today and have to admit, I found some dismay in the construction.

I pick it up by scope, body, stock, but never the barrel so I don't know if that's the issue.

Did see a thread in the last week about someone remaking the securement of the Impact's liner. IDK if it needs it, lots of folks out there getting good results w/ it as is.



Have you had the scope off and checked the picatinny rail is good and tight?



There's so many things it could be and I'm certainly no expert.
 
I bought my impact new, from day one there were numerous rattles and twangs every time I fired the gun, loose hammer, loose hammer spring, loose anti bounce spring guide, loose valve return spring (uk spec) a rattle from the shroud and the pellet doesn’t exit through the centre, although it doesn’t clip it can’t help either. I have already made it shoot a whole lot better but there is still a way to go before I will be happy with it.



I think it might have been me with the improvement to the liner security, I was going to fit it to my impact but decided to test the liner on one of my other guns that doesn’t suffer form poi shift. So I have had to order some more parts.
