If you're shooting 115grs of BH209 by WEIGHT..... you're exceeding the maximum load recommended by Western

I was tickled as h$&l Then the sabots were a really light colored blue and loaded super easy as compared to before where they fit real snug. Then groups went to 3 1/2". Tmz are showing promise especially with 115 gr. they are about 1 1/2" but my confidence is south from an occasional flyer in every group. Ill experiment more.
. By WEIGHT..... the maximum load is 84 grains
!!!!!!! I never caught that when you posted that in post #8
and evidently no one else did either......... YOU'RE WAY OVER CHARGING. Unless I'm reading it wrong.............
It appears that you're not converting volume to weight properly and you should start IMMEDIATELY. The conversion number is (.7) With a maximum load that Western states is 120grs by volume
you calculate it like this....... 120 Volume X .7 = 84grs weight. If you want to weigh out and shoot 115grs volume, you would take 115 Volume X .7 = 80.5grs weight.
You are over charging and beyond it being dangerous, you're wasting propellant and if you're having fliers, that could be one of the contributing factors.......
What seems to have been determined by many shooters of Encores or Pro Hunters, is that most of them shoot the most accurate and with tighter groups, when shooting between 100grs and 110grs VOLUME
of BH209. That range seems to work the best for the Encore platform rifles.
I have a specific load for my Pro Hunter and I can assure you, it shoots better than my ageing eyes. On my good days, it'll shoot 1/4" groups at 100yds, 3/4" groups at 150yds and less than 2" groups at 200yds. But.... that's on the days where I'm doing MY job
and I'm not getting any younger. I've also done $35 worth of modifications to the rifle, which make it a much more accurate rifle too. EVERY Encore platform rifle IMO should have these modifications, which greatly increase accuracy and shrink group sizes. If you're looking for the ultimate grouping from your Pro Hunter, for about $35 and a little time, its ALWAYS good money spent!
I shoot 107.1grs VOLUME or 75grs weighed. I use the Barnes 250gr TMZ bullets and CCI209M primers. When shooting for tight groups, I twist the 1/8" drill bit into the breech plug flash channel after every 6th shot, then fire just a primer through the rifle, then shoot and repeat the process. I also seat the bullet HARD on the powder with a solid "thump". Actually, when using a precision force gage, I seat 105# +/- 5#.
I'd suggest backing down on the propellent and start using one of the magnum primers, either the CCI209M of Federal 209A. The magnum primers ignite BH209 better and certainly more usefull in extreme cold weather, of which we sure as heck haven't been having......
