.30 cal Marauder rifle

[HillGSA]

Recently, I got the chance to shoot a .30 cal. Marauder rifle.

The rifle is not mine, so I did not shoot it very much. I did make a short video - I thought I would share. There’s more information in the videos description - click on "show more"

They are quite a bit of fun... I have some work to do to complete the shroud/ldc but once that is done I plan to try it against some tree rats. At full boogie, this one is capable of 13-14 shots with 70 gr cast at 1000 fps. Turned down significantly, it is *VERY* accurate with 44 gr JSB...and more shots too.
cheers,
Douglas

I noticed the accuracy right away too. Those bigger caliber pellets seem to stay the course easier/better than the smaller caliber ones. In comparison, I was missing the metal swinging target with the .30  cal. - noticeably less often.


Maybe leave your .30 cal. at full boogie and use one cast to take out a squirrel - and a couple of deer at the same time

The new King Heavies seem to fly better in the wind than the 30's. It is a limited data set, but seems to follow the reports of the Heavies having a 20% better BC than the 30 cal pellets. In calm, both will bring giggles over the small groups...some of those, held to 5 shots are very small. The 25 having a BSA barrel, and the 30 packing a .590 OD, 26" twist from TJ's fitted by RTS Machining.
cheers,

So, sounds like if you "had to", pick one over the other, then the .25 would get the nod ?

Here's a couple of pictures of the rifle :

Is this something you are going to modify for others?
I happen to have a extra gen 2 laying about.

I have noticed the jab pellet gets moved around in moderate to high wind also, more than it should also. Be nice if H/N join the band wagon and develop a .30 cal pellet around the same weight.
By the way, nice build 👍🏻 almost looks like that citrus brand moded out of Florida

This is pretty much a one time deal. I can answer your question in more detail if you would email me at: contacttimhill@gmail.com
Thx

I recently finished my .30 Marauder and it shoots amazing. I used one of Tim's valve and gauge blocks, and the barrel and bolt were done by Roy Weid at Mountain Air same as the gun in Tim's video. The low shot count of 7 and avg fps of 835 might be to low for many, but for drop in parts it makes for a *(&^ of a package!! The 1:26 TJ barrel and 44 JSB's make for a very accurate combo.
Roy does a really nice job on the barrel and bolt. I think the .30 kit from Roy was $250 for the barrel and bolt and a bag of spare bolt probe o-rings. I put the .30 top end on one of my guns with WAR valve and hammer and it shot almost identical numbers. Between 2 different power plants, it was evident that whatever the gun shoots .25 cal 43gr eunjins is about what it will shoot as a .30 with 44 jsb's.

A thanks to:

for the heads up - about the .25 cal. JSB heavies, being the more accurate pellet, when compared to the .30 cal. 




I just set up this rife for a higher power output ( top rifle in pic ) and will order some of the .25 cal. JSB heavies, to try.


Also;  I set up the rifle in the bottom of the picture, yesterday for 25.39 grain pellets, at about 810 fps.




On both of these rifles, the pressure tubes have been shortened 3-3/4" ( 20-3/8" long ) . Now the rifles balance more toward me and have a handier feel to them. They are also a bit quicker to aim and should be easier to carry around for extended periods of time. I know the shot count will probably end up being a bit less, but for me, the handiness will most likely be worth the trade off since I do more shooting while "on the move", not at a bench.

I didn't want to sound "covert", just respecting rule #9

Tim, What shot count did you get with the "30 cal" and the shortened air reservoir?

I haven't tested a .30 cal. with the shorter reservoir

What Hammer spring weight?

[stanley1131]

Nice looking marauder.. light too! Do you know where I can buy that pistol grip for the marauder?

What Hammer spring weight?

The .30 cal. tune was with a hillairgun.com  hammer spring - rated near 12.5 lbs./inch ( I had some custom made ).

[WHITEFANG]

Was a 17 lb tried? Or would that be too much?
On the .25 it seems to work very good in the marauder?
