How about adjusting your seating depth? What is the max COAL (where the bullet hits the lands). I have had a similar problem which I fixed by not seating the bullet as deep. My rifle had a long throat and didn't like the jump.
can't make 180's out of my 308 work

I check on loaddata 180gr with H-4895 runs as low as 33.0gr's with a Hornady A-Max, a 180 gr Barnes TSX BT start load is 38.0 gr of H-4895
but I'm betting the OP was looking at IMR 4895 , as that runs a bit lower , ,
but that still should not give high psi, (hard bolt lift ) so I'll bet case lenght , for the high PSI and mixed brass for the bad groups ,

Pick up brass may well be an issue also. Ive got some Canadian milspec brass thats more than 15gr heavier than lake city 7.62 brass. Max loads in this brass is at least 2gr less than the lake city.----Two different points of impact. Sorting brass and getting some specific advice as to what load for what brass will probably make a big difference.

i may not no what im doing but i can read im useing the hornady manual and it starts at 33 gr and ends at 38.4 thank you very much.
Just dont stop trying, I have been in your boat and thought i have tried everything, with poor results and then all the stares align and it comes together.
Recently i had my 11 year old with me in the reloading room, it was his first time and he was enjoying helping. I was reloading for my FNAR which i have been trying to develop a load for for the past year. I can't count the different bullet and powder combinations that i have tried. Any way we were done but he wasn't so i decided to load up some sierra 180 game kings that i had for my 300 so we could spend some more time together. After the trip to the range i had the same results with all my loads( about 1.5 MOA) except for the 180s which stacked in at 1/2 MOA, just one rough hole. Now i just have to duplicate it
. Any way just trying

as the OP said , he can read,
so it's not the powder charge , so it's time to look at the brass

I havent tried those powders but here is my recipe, 43 grains of IMR 4064 set to hornady book length using the 180gr BTSP from hornady. Its on the hot side so work up. My rifle is a savage model 12, all brass i use is either federal or winchester that i shot new and reload. Brass is trimmed after first firing to 2.005. Primer is fed 210 match. Group size is around .5 in at 100 yds. I use the same recipe with the 178 BTHP from hornady and shoot at 1000yds. I have tried this load with a friends savage mod 10 with same excellent results. The winchester brass does hold more powder than the federal. Any questions feel free to ask, i know how it is to get started.
