Hornady or Sierra

I loaded various loads with 140gr hybrids..
Loaded different to the last time..
2 different powders, RS62 and RS60..
Tried 6 more 130gr eldms and some 140gr amaxs.
It was the first time ive been out since 28th September..
i had open heart surgery on the 17th of October and my breathing and stamina isnt great..
getting my breathing right to shoot wasnt great either..
As the throat wear has been alot I wasn't sure what to do so I lengthened a little from my last test.
Sot prone off a bipod and a bean bag..
Most are 5 shot groups..
Top row 2nd in from the left was jumping 52 thousandths wow..
The 130gr eldms I thought I'd try in the lands, ok group 9 thousandths in the lands..
Could of been better if my breathing was better..
It held up for the next group the 140gr amaxs which was with a silencer on as its my hunting load..
Other groups were shot with a muzzle brake on..20251210_183140.jpg20251210_183130.jpg20251210_194403.jpg20251210_194309.jpg

It depends a lot on a particular barrel.
I have three 6.5mm CMs.
Two like heavier bullets and shoot the 140 to 147 gr bullets about the same with a slight advantage to the 147s.
The third likes lighter bullets and shoots the 130 gr bullets better. The 130 TMKs shoot the best, but the ELD-Ms shoot very close to them.

I find that the Hornady 143 gr ELD-X bullets - made for hunting shoot as good as anything in the two barrels that like heavy bullets.
The 142 SMKs shoot well, but my two heavy bullet rifles shoot the Hornady's slightly better. I measure all my 5 round groups and have plenty of data for each bullet. All three like H4350 powder best, and the difference in best to moderately accurate group sizes are pretty small.
