New 392 Steroid

[3crows]

I got my 392 back from Mac1 Saturday. Did not take as long as I had thought it would possibly. The USPS is running slow in both directions. This rifle and it's buddy, another 392 were in a thread wherein I was trying to decided which to Steroid. I should have just sent both and may yet. But I got the new rifle back. It has very few shots through it before sending it to Mac1, just enough to verify mechanical function and good accuracy.

I plan to refinish the stock  and slightly reshape the wood to provide a more fitted and even look. I removed the rear site last evening because I decided not to use my Baker scope mount but to instead go with the Mac1 and scout scope with my spare BSA 2X20 pistol scope. The rear site interferes with the ideal position so it is now gone.

Does anyone have a torque for the Mac1 scope mount on a brass barrel?

Interestingly the rifle and scope seem destined to be one. It was zero at 25 yards out of the box, no adjustment needed. I have had this happen before but not often, zero out of the box! And never on an air rifle.

Pumping, well, it is not as difficult as I had thought, actually rather easy. I can easily get to 12 pumps lickety split with effort about equal to my dual spring modded 392 to eight. Rifle seems to pop pretty good when fired. It retains no air at 12 pumps, full dump, with Crosman/Benji 14.3 grain pellets. It does retain a little air at 14 pumps. But 12 is fine with me and about the maximum I think I need anyways.

I wish Boyds made a custom stock for these, I assume there is not, maybe I should do a more exhaustive search? Otherwise I will strip this one and make it look pretty.  It is not bad now but a Steroid should have a more custom look maybe.

Congratulations on getting your Steroided 392 back from Tim, James.
You’ll find that six pumps are usually plenty. Remember, six pumps on a Steroid is usually equivalent to eight or nine on a stock 392.
Don’t forget to use the Secret Sauce. Enjoy.

Hi James.

Here is 45flint's C9A Steroid Silver Streak with a custom Corcorran stock.

Best Wishes - Tom

Nice looking stock Tom. Too bad it cost more than the actual rifle.

  I love that Corcorran stock but it was more than I would pay for a 392 stock.  I hated the log shaped pump arm on my 392 so I reshaped it and thinned the whole thing down a bit.  The wood took the new stain pretty good for whatever it is made from.

Yeah, that is more like what I have in mind. Fill that pump arm gap some and thin the stock down and re-stain it with good materials. What did you make the white butt stock spacer from?

Thanks guys,
James

   The white spacer on mine was made from some scrap hard plastic that I traced the butt stock on and jig sawed.  The stain I used was American Walnut by Laurel Mountain Forge for muzzleloaders.  Its solvent based probably alcohol. Filled the pump arm gap with some 1/8'' thick hardwood glued and screwed into the stock side not the pump side & sanded to shape.

James,

As far as the torque on the Mac 1 base... I don’t know any specs, but I tightened mine with the supplied Allen wrench as tight as I could go by hand, and it did’nt leave a mark on the bbl. I know because i’ve moved it’s position since then.

What’s the velocity on your steroid 392?

Very nice job on the stock!

Thank you Mr. Van, very useful. I am going to do similar. I have some .032 G10 in white and black. I am going to make a white butt spacer with one piece and for the space between the pump arm and rear stock perhaps a white and black and then shape the stock to reduce bulk slightly and fair it more smoothly.

So today while sitting out I shot "The Hammer" (725VTR) and the new 392 Steroid at 25 yards. The target on the left, ignore the outlier three shots off hand, I was playing afterwards, a six shot group with the 392 Steroid and the right a six shot group with the 725VTR:



The group for the 392 would have been tighter but I added two clicks of up, one and then another, thus the slight vertical string. These were both shot sitting with elbow on knee and a right cross wind.

James,

That’s some very good semi rested shooting at 25 yds.
Especially considering the scope adj. being made while shooting the group with the 392.

Thanks, the bottom two holes were new scope, no adjustment, fresh from the box. Added a click up. Shot two more side by side and added another click and they moved up to the two stacked ones. Leaving it there for now until the rifle settles in some.
