All available .172" you load for 17VHA
I would like to start an archive for bullets shot in 17VHA, just favorite loads and bullets used. Below is what I have launched from mine.
If you have any primer recommendations it would also be much appreciated. I have been using CCIBR4, CCI450, Rem 7.5, & Winchester Small Pistol. If you have any others than those depicted above, please add them with a photo. If you have load data, it would be a nice thing to have it all in one place in a similar fashion to the 17 Squirrel, 17AH, and 17HH. I think that there are about as many out there that I have not yet shot, and I guess that you could throw any crazy subcaliber saboted projectiles in there as well. The military has at a couple of junctures persued subcaliber projectiles with mixed results, good and bad. Last edited by 17tbs; 05-13-2017 at 03:25 PM. |

Weight
To give you a crooked answer instead of a straight one, yes.
Individual weight is.... 55.32gr each from an average of 8 with a CCIBR4 primer. That primer is the crooked part. 124 pieces of primed brass with the "4.6x30 DAG 1081143" headstamp, and 50 of the brass with "DAG 15" headstamp. I'll give you a more complete answer tomorrow after I get the weight of the primers subtracted from that 55.32gr weight for primed. 103.76 grains for 30 primers, 3.458gr per primer so 55.32gr-3.458gr per primer = 51.86gr per case. That comes out to 134 cases per pound of unprimed cases I altered all of them a bit with two alterations to the primer pockets to "de-mil" them, I used a Phillips head in an electric screwdriver coupled with a once over with a deck screw star drive that seems to fit a properly sized primer pocket perfectly. This took about a half a grain of brass out of the primer pockets, repriming is now pretty painless. As an aside, a 2.80gr load of HS 700X under a 20gr XTP goes 2141 fps for an average of 3 shots. It forms the brass well and provides a nice ballistic copy of the 17M2 rimfire if it had ever been loaded with a 20gr bullet. That also makes a pretty decent bunny or squirrel load under 50yards.

A beginning to the data for 17VHA
This will get updated as I get new data from shooting over a chronograph.
32gr NOE cast 700x 1.04gr CCIBR4 1054fps 32gr NOE cast 700x 0.84gr CCIBR4 905fps Note: AS CAST from PURE lead, these NOE run 33.4gr 30gr Nagle shortened to .557" 700x 1.4gr, CCIBR4, ended up at 827fps. 25gr Rem PLHP, 700x 0.85gr 524fps, 20gr HMR Gamepoint 700x CCI BR4 2.7gr gives right at 2150fps, this is a good rabbit and squirrel load for eating, and also works well with either the 25gr Rem PLHP. or the 25gr HNDY HP. 17grGSC SP solid copper spitzer no hollow point 300MP CCIBR4 8.70 3705fps 8.82 3478fps (why so low I don't know) 9.03 3741fps 9.08 3693fps (again, don't know why it went the other direction) Pineapple was my most convenient test media for the 17gr GSC SP. This one was hit at an unknown velocity the brass turned out to be single use at 9.7gr 300MP. All shots had no problem extracting, no loose primer, etc. Has anyone experienced velocity variations that do not make sense? I am using a chrony chronograph, has this model given others bad readings? Last edited by 17tbs; 05-28-2017 at 06:48 PM. |
