65 grains of h4831 with the 200gr accubonds using my abolt its nothing to touch at 100 yards. cant remember the speed i have it wrote down somewhere (2700 fps?) speed is not as important as accuracy and this is not a compressed load. love the 325 cartridge.

I'm loading 65gr RL-17, CCI250 primers, and Winchester Nickle brass behind 200gr Accubonds. Seeing 3020fps across chrony, and shooting 3/4" at 100yrds. This is through a Browning White Gold Medallion, that has been accurized by a very reputable gunsmith.
I started working up loads and was getting frustrated nothing was grouping good. Took the scope off checked the mounts the were a little loose so I re-tighten start again results still th sh*ts took the scope off again one screw was loose so I pulled it all off and put a little lock tight on them. Re sighted the rifle today and it seems to be looking a lot more consistant. Now to start over. What a pain in the ass. I guess thats what I get for gettin the guy at the gun store to mount and bore sight instead of me doing it myself.
I have tried a whack of loads for this caliber - my gun liked 200 accubonds @ 2.88 col with both rl17 and 4007ssc - went up to 67 gr before press signs, both powders settled in around 64.8 - 65.5 grns, and depending on load they ran around 2940(min) -3050fts(hot). . It didnt like 4350 or rl19. I use regular win primers and win brass... both rl17 and 4007ssc grouped an inch or under at 200 once I found the sweet spot...the winner for my gun was 4007ssc by a small margin.
Key to my gun getting good groups was to fire 3 them let it cool right down... if I didnt do this, the shots would climb dramatically despite the bedding and such - i'm guessing too thin (and fluted) of a barrel.... barrel is 0.520 at the tip, or 13mm, bullet is 8mm, meaning there is a barrel wall thickness of only 2.5mm!
On another note my accuracy went real bad this past month - checked everything, tried tweaking loads again, then finally went to change scopes and then found the front screw on the front weaver base was sheared off and the rear one was oval shaped...... fixed that and back came the 200yd 1 inch groups!
