Apparently Savage is introducing a new straight pull action - Savage Impulse:



Looks like modified Heym SR30 action to me - ball Bearings popping up into a circular grove in the front of the receiver. What do you guys think of it?
 
d:h: cheaper to make I suspect, but still an answer to a question no one in North America seems to be asking. Maybe more of a focus for Europe. I wanted an Acera, but they werent available for long here.
 
I suspect issues with:
  • little to no primary extraction, it will stick with reloads
  • no idea how the balls will like any sand, if something blocks any of the tiny balls to go retract back inside it will shut dead. If a ball cracks it will probably totally jams it with fragments
  • as all straight pull and SR30 specifically I suspect it has to be operated fast, which means it will make quite some noise. Probably you will have to bump it in for a good measure. It would be really nice to have rails to move on, like blasers do, instead of just rattling cylindrical bolt.
  • I don't see a point of reversible handle if you can't switch ejection side
  • the overall length is the same as traditional 110, which is a pity if you look at how tiny Blaser R8 action is.
 
i've been told in europe, being mostly commie or hardcore fascistic, they have a real hate on for semi auto hunting rifles. i, personally, wouldn't mind one of these is 358 or whelen, not that thats likely. 338 fedaral would be OK too.

Looks as if there is compound leverage built into the initial opening sequence.

No I disagree. If you look closer, you have to take into the account that primary extraction is only possible once the ball bearings are retracted and the action is open. If you look at the x-ray animation at a lower speed you can see that the all the rotation of the bolt handle happens before the balls move in. It appears that it is using rotation stroke to #### it first and then retract the bearings, once the bearings are in and the bolt is moving back and extracting the handle is already turned all the way and the bolt is just sliding back.

It can be an issue with the animation being a bit simplified or out of sequence a bit.

The bolt handle appears to leverage against the left side of the receiver, trick has been used before in very low lift (20 degree) bolt actions for primary extraction.

Maybe I'm missing something, but I don't understand how this can be the case if the bolt handle is reversible.

No this is not it, BMS CAM or for that matter ARC Archimedes actions are applying leverage to the bolt body once the bolt is UNLOCKED.

For the Impulse it is clear from the animation that the ball bearings are extended and the action is closed, so you can't move the bolt body or primary extract at this point. The turn of the bolt handle on Impulse is acting on the cocking link) for most part and at the and of the "leverage rotation" it is moving the bearings in.

Maybe it's that dinky little wedge on top of the cocking piece that is doing the primary extraction when the bolt handle is pulled back. It better have some sort of primary extraction or it will be a useless pile of crap...
The animation is not really impressive or inspiring to be honest, it looks like a frail dinky set up from here.

Sounds like a description of the Liberal Party,and unfortunately a large percentage of Canadians. I had a Heym SR30 and liked it except for its stock design and slow to use safety. I don’t own a a Savage rifle and never have but they make accurate and very functional rifles for a good price. This shows that they are still willing to inovate and lead in the North American market. I am very interested to see where this goes.
