Bone Collector Accuracy problems


Recommended Posts

I recently switched to BH 209 powder, tried several different bullets and powder charges out of my Encore Endeavor with the Nikon BDC 3X9 scope and the best load for this gun seems to be 100 gr BH 209 and 300 gr. Hornady SST Low Drag. Three shot group at 100 yards was 1.5 inches and at 200 yards the group held to 2.0 inches. I tried the 250 Hornady SST Low Drag and it worked okay group was about 2.5 inches at 100 yards and 7 inches at 200 yards. The TC 250 gr. Shockwave easyslide did not work for me at all, at 100 yards they were not even on the 12 inch target that I was unsing! I really like the BH 209 powder, but I still would clean you gun after shooting this or any other powder. You might want to try the Hornady SST 300 gr. Low Drag out of your TC.

Good luck,

Dennis

I have been shooting BH209 for over a year now. You need to try a tighter fitting sabot. BH209 really shines with a snug fitting sabot. I use the Harvester short black sabot and the 250 gr. shockwave with 110gr. of BH209. If I do my part I can get 1 inch groups or better at 100 yards. My Endeavor also likes the Hornady FTX .430/265gr. with a Harvester green sabot. Both of these combos will shoot MOA if the shooter does his job. Hope this helps.

Yea,I think the easyglide sabot is your problem. I am a member on a few other forums and almost every Triumph and Endeavor that I have heard of shoots the 110gr. Bh209 and the 250gr. shockwave with a harvester short black sabot really well. I'll be shocked if this doesn't get you close to 1 1/2 inch groups or better at 100 yards. Of course, you'll have to do your part.

I'm a total greenhorn when comes to ML shooting. I had similar results with my new Triumph shooting 250gr shockwaves w/ez-glide sabots, and 777.

I "lapped" barrel with JB and loaded 300 grain Shockwaves with the black sabots, 115grains of BH209, and Federal 209A primer.

I'm not certain if it was the JB(bore is still "tight", smoother I think) the Blackhorn 209, the heavier bullets, or the black sabots... I don't care, I shot 2, 3/4" groups @ 100yds that'll get me through hunting season.
