More duplexing............

[Richard]

The weather today was a little warmer than last week. It got up into the 30's with light wind and a mix of clouds and sun. (Bill and Herman actually got the inside temperature up to 64* by the time we packed up at 1:00 pm. I sent some 34 shots down range with varying results. My best occurred on target #3 which is a duplex of: 5 gr. N-110 under 65 gr. of N-120 with a 200gr. SST and Blue Harvester sabot. I shot this group specifically for Ozark since he likes "Accuracy!"
Prior to shooting this group, I shot the same charge only with a 200 gr. XTP. While it grouped OK , it was not like the SST's.
Load /target #6 was not performing so it was terminated after two shots.
Target/load #4 was shot with some 180 gr. XTP's which Herman had bought. He also got similar results. That load was ended with just four shots
300 yards was a little challenging. Target #7: The wind got me on shot #3. I only had four of this charge so hence the 4 shot group. It definitely had the potential for MOA accuracy
Target #8 could also have been decent. This was sabotless with the 200 gr. FTX. Shot #3 loaded quite easily and subsequently produced 150 fps LESS velocity which accounts for the low shot. #4 ? The grass was blowing left to right so I have to believe it was the wind. Elevation was good.
All in all, it was a good day. We had a couple of other club members stop by and some good BS. Going to take a break from the ML next week and work on the 600 yd. target rifle. I do all my loading right at the range so I bring a lot of "stuff!" If I bring the ML, it gets to be too much.

Your sabotless bullets, are they sized or sized and knurled?
Groups #7 and #8 are pretty impressive...especially 1,2&4 and 1,2&5!

good report and good shooting as usual, might have to try that 110/120 load and see what happens

[Richard]

Edge..........Sized down to .448" and then knurled up to .4515" or thereabouts!

Very nice shooting Richard. How is the recoil on the 110/120 load.

Richard,Great shooting.I guess i will have to knock the dust off that n120 and give it a try.Great report.

I tried that same load of 5/65 N-110/ N-120 200 SST today. Shot#1- 3,084, #2- 3079, #3 blown sabot missed target the first two shots were .5" I also tried it with 65 grns. straight N-120 it was a real good group. Have you blown sabots using this load? Going to try again tomorrow.

Thanks John

John...
What velocity did you get with the straight 65gn 120?

#1 - 2,911 #2- 2,889 the second two did not record, getting to dark. Zen I got the chrony that you suggested works good easy to use. thanks

That seems like more than plenty of speed...I've got a lot of N120. It's definately something I'll look into. Glad you like your new chrono. I made up a bunch of wooden 3/16" dowels the same length as the steel rods that came with it. I use them instead of the steel ones. When a sabot hits the wooden rods they break easily so that no damage is done to the chrono housing. If you shoot the straight N120 anymore keep us posted.

I will be back at it tomorrow bright and early, depending on the wind. I'l let you no how it goes.
Good idea with the wooden dowels.

Jumpin' in on you chrono side bar comments...I use those bamboo skewers you use on the grill. Buy in grocery store for a couple bucks a pack. I roll across a flat surfacea with a sharp knife to crack the surface all the way around a couple inches up from meter end so it will snap off/shatter with minimum impact on chrono. Works great. Simple. Cheap.

Uncooked spaghetti works too, as long as you aren't needing the skyscreens. If I don't need the screens I shoot it without anything too.

[Richard]

Smokeless77.............Actually, I have not blown any sabots with that load or just about any of my HV loads? I think.........one time, I did blow one but can't remember what I was shooting. I can see your longer barrel is getting you a little more speed than I can get with 23". Herman shot an identical load as me (15/55 ---------N-110/H-322) and where he got 2900+, I got 2800+. I figured it right about 50 fps/inch of barrel. His is 25 vs my 23"
You need to try the 17/56................N-110/N-130 load that gets me to about 2950 fps. Keep the barrel cool and I'll bet you don't blow any sabots

Are these OAL or usable lengths?

Standard Savage plug drops off just under 2 inches, and about 1/2 inch less for a recessed plug.

[Richard]

Edge............These are OAL. It seems a little easier to just deal with "what you basically see!" I am using a recessed (1/2" x 5/16") plug which holds right around 11 gr. of N-110. And......I believe Herman was using one of my recess plugs also. And yes, I know there can be differences in velocity readings between chronographs. So this was just a generalization. It would probably be more meaningful if the rifles were shot across the same chronograph.

Thanks I'l have to pick up some N- 130
