The blow-back is dependent on which ignition system you are using. That is one of the little quirks - I speak of. If you are using the Remington 209 system you will get a really decent amount of blow-back if you a using a Cabelas 209 system it is mostly gone. There is a huge design difference between the two. I use a 20 guage shot gun plastic case as a weather shroud - there is not enough blow-back to cause that thin walled shell any problems.

The 24" Remington was rated at 120 grains because of the length of the barrel. The 26" is considered to be a magnum and 150 grains in Pellet is OK.

Actually in my conversations withRemington, and un-officially, the only reason the 120 was set was that was all the barrel was capable of buring at that time and that was with a standard #11 cap. On their web site at one time they said the same thing. This was win the "magnum" rifles were first coming out and promted their decions to come out with the 26" magnum barrel.
