Primers are the old Winchester white box.
I have acquired a good supply of them over the years, Federal 210 will work just as well. The old 110 has never done as well with pistol primers for me, I put the primer
wad inside the case also. Loading method was the same for this test, as my standard Express load, only change was the powder, I tried 107 grs first it was too much filled the case full even with a drop tube.
What I search for, is a load that gives me a powder height of .190 to .215 from the case mouth after drop tubing and placing a .060 veg fiber
wad on the powder column, I compress the powder then .385, a poly
wad of .056 is placed on top of the veg
wad, finally the
felt wad 1/8 last. The above is only used for Fg Goex powders. Swiss Fg Jimbo uses an amount that needs .050 to.100 compression. However we have had the phone lines heated up past 3 Days over this Eynsford, he will adjust the
wad stack to get his OAl length set with the money micro-mini. He has had excellent luck with Fg Swiss, year before last, at 800 yards at Byers, we had quite a day I was in good form spotting and was Jimbo was making great breaks he posted a new national record of 148/150 for 15 shots
last year at Byers he took the big money match no spotters.
I have been shooting this same old rifle since 1994, this is barrel #2 and breach block #2, Kirk went through the lock on the rebarrel and replaced the block at that time also, just shy of 20k mark that was 2005. I spent 2009,10,11,12 shooting Dora and promoting the Tollofson class. In 13 I went back too my old favorite, it never missed a lick, did very well at Phoenix, another Creedmoor cup, and A Scope regional title, Raton the scope title. I spotted for friend Steve Hamilton who won the mile match with it setting a new record, plus I set a record of 8/10 hits in one relay.
10 years ago I started making a serious study of bullet bases even shooting off the target at 1000 yards the recovering bullets, my shorted version of Dan T's NASA mono-groove getting the most attention I finally came up with a
wad Combo that gives a nice flat base and no fining on recovered bullets.
You can find, a good load with Goex at about .250 compression, it will shoot very well to 300 or so, it will show some vertical by 600 and more so at 800, I upped the charge until vertical went away even at 1000. I had two loads of express that shot well in my book 106 grs and 108, the 106 would not hold my 36 inch bull for vertical at 800, where as the 108 did. The 110.8 grain load if I do my part.......is like a lazer beam too 1 mile.
I spent years finding this out, it is all in Edwin Perry's book though. Perfect you fouling control, decrease the vertical with more powder.
Remember though this just pertains too match-target rifle accuracy. Steve Rhoades helped me test this stuff at Phoenix at long range, on practice day, we both were impressed.
I will be giving it a go at Byers in Aug going after that money match, and will be using it in Sept At Raton.
