H110 dilemma resolved, and a forend question....
« on: July 20, 2003, 12:45:47 PM »
I took some of the suggestions that I was given on here, mainly to step up the charges on my H110 loads to closer to maximum, and I was treated to what I consider success.  I'll post some pics later, the wife has the digital camera filled with our 10 week old daughter's pictures. :)  I loaded up some 320 gr. cast bullets from Lloyd Smale, and some 360 gr. and 370 gr. from Lloyd, all gas-checked.  I shot at 50 yds. with a 4x Leupold scope and a good bench rest with sandbags.  26 gr. of h110 and the 320 gr. turned up a 1 1/2" vertical group, 27 gr. of H110 with the 320 gr. turned up a -1" cluster, I was ecstatic. The 360 gr. with 25 gr. H110 turned up two holes touching and one 1 1/2" off that could have been my error.  The 370gr. with 23 gr. of H110 turned up a horizontal 1 1/2" group.   Finally, some acceptable groups from H110, although they sting the hand quite a bit more than the Unique loads I use for plinking and practice
Is there any chance someone could run these loads through a loading program and see what velocities I should be getting with these loads from a 12" barrel?  My chrony is on it's way sometime in the near future, but until then I have to estimate.
Finally, some acceptable groups from H110, although they sting the hand quite a bit more than the Unique loads I use for plinking and practice.
Onto my next problem.  I have a custom grip set from Denzel Roberts that works great, with one exception.  The forend screws keep backing out, I can shoot about 20 plinker loads or about 5 of the heavy H110 loads before it's time to retighten.  I called Denzel and they are standard thread scope 1/2" long scope screws from Redfield, and I've tried blue Loc-tite, but that didn't make any difference.  I've screwed them in without the forend and they only grip with four or five threads before they bottom out.  The other issue is that they are hex heads and I'm trying to tighten them down so hard that I'm afraid I've stripped the hex heads out for the most part.  I can get the same screw from Brownell's in a Torx head, but there are a dozen of them in a package, would anyone like some Torx screws of this size, I'd be willing to split them up, since I only neex two at most.  Any other suggestions for getting the forend to hold in place are welcome, because as you can imagine, accuracy goes down the tubes when it loosens up.  Thanks for your help with the H110 and I hope you can help with this.
Sincerely,
Selmer

H110 dilemma resolved, and a forend questio

I don't know what they would be doing in your 12"bbl but in my SRH 7.5 a 330g LBT with 30g H110 is right at 1520. (I have a slow batch of H110) plus the cyl gap loses some too!
On those screws are they bottoming out and not tightening up on the forend? If they simply bottom they won't stay tight because as I'm guessing there's not much meat between the bottom of the hole and the bore. Everytime you shoot it expands or rattles by and loosens the screw. It should tighten on the forend and not bottom in the hole. You may have to shorten the screws or simply place a thin washer between the bbl and forend.   Just a thought.

about those screws...

I think Duffy may be right on the mark about those forend screws bottoming out. You might try a folded business card, or electricians tape (a la Graybeard) over those screws, just to see if that stops them from loosening. If it does, just shorten the screws a thread or so, or bed the forend a little off the barrel with some bedding compound (my choice).... Bug.
