The 30 LW is no good. Better to get the 30 pellet from TJs. I have one in a condor and it does real well. Made the finals at EBR twice with it.


Don't ya think telling him AFTER he ordered is a little late? LOL!!! Good way to burst the anticipation of a new toy though.  ::)


I will admit the advice is solid. Just improper edicate.  If given before ordering, it would have been golden!

Greetings.
Well yes the LW of .30 is 306 / 298. With twist of 1/16 ". And can not say that" not good "is that there is put the ammunition you need. The LW with choke goes very well with pellets below 300 m xsg.
    My LW gun without choke pulls the jsb .30 hasya pellts very well over 300xxsg. And the 90 grains of this mold:
http://www.accuratemolds.com/bullet_detail.php?bullet=30-075A-D.png.
  these move between 308/297 m xsg in 10 firings first.This bullet works well just like it comes out of my mold.
It is sure that Mark will do good results with his LW barrel when he finds the minimum power setting for his 30 pellets. From 250m safely xsg, and at lower speed it is possible that too.

I just ordered a .30 magazine from WAR which is designed for the WRAP/Flex that should work in the .30 Marauder breech after slightly milling the breech.
The advantage is that it will allow a longer slug/pellet. If the magazine doesn't work it will up for sale.

I was very interested in the thread PCPack had going on the W/L Poly barre, and wanted to learn more about it. Sadly,it got derailed and nasty to the point it was locked.

FYI, there is a NEW .30 cal Lothar Walther barrel which has been custom ordered by Pak Protector and others, specifically for pellets.... It will be a smaller bore (0.302-0.303" IIRC), and a 36" twist, with Polygonal Rifling.... If THAT is the barrel that Mark has ordered, he should be a lucky mann (sic)Ö.  8)

I ordered a 15 and a 17 lb flat wire springs which seem to cock way easier than the weight suggests going to try the 15 lb first on the ssg for the 30 Cal . I might try the lighter hammer first also before I go to mass 40 gram hammer the lighter one is 31 gram

I think you will find the 17# better, These flat springs are not rated the same way the coils springs we normally use are. Totally different. Cut as little as you can possibly get away with before coil bind.


In fact, several users have used a washer between two of the 20# springs to get the velocity they are needing, or matching what they already had, but with much lighter cocking efforts.  ;)

I just received the .30 Magazine from WAR for their .30 WARP. It is exactly the same as my Marauder .25 except it is .062" wider so I will open up the breech by that amount and it should work.

Bob,
  I spoke with Jim and his recommendation was "You would need to mill the back of the magazine pocket for them to fit"  Wondering if it is just the pocket that needs to be machined?

The measurements that I took looks like it will fit the same as the .25 magazine after .062" is removed from the rear of the magazine pocket. Hopefully I will find out in the next couple of days.

Bob Pratl ,
I could be wrong but you may want to check and make sure that your bolt probe tip will have enough clearance once pulled all the way back for the magazine to cycle. Not looking at mine right now but if memory serves me right itís pretty close. If it didnít clear then bolt probe would have to be shortened which then in turn wouldnít seat your bullet/pellet far enough past the barrel port. A sixteenth of an inch donít sound like much but sometimes it call make all the difference.

Just saying,
Chris

I think the reason I get So hi a FPS is I begged for a long barrel, It is 20 inchs from front of rec block to muzzle. And like I said the port is as big as I could get. I do have to clean it often as lead will build or wax not sure which, maybe both. I have been using bike chain wax for lube. The carbon fiber on the out side of the barrel helped out a lot for group size. And I do use a lot of air in it. It does not shoot cast slugs well however. I think you will have a ball with this 30 cal m-rod
