Beretz have you tried magnum primers with your R26 loads? A couple of people said it reduces ES and can improve accuracy. I haven't gotten around to try it as I have 3x more standard primers than magnum and want to use those up.

Yes sir, with 26 in the 25-06, 243 and Swede. The BR2s work best for me. Couldn't see anything where the Magnum was warranted. I do use CCI250's in the 270 and 7 WSM and the larger cases I load for.
Thanks getting ready to try it in the 270 wsm and 300 wm and think I will just start with magnum primers with those two.

Thank you. Have had a good read through. I had started my thread as I wanted to focus load info on 140+gr bullets with big game as the intended target.
You're 100% right, this thread is a great resource! Thanks again.
Been kicking the tires on a swede. Gew98 action, 24" 1:9 Shaw barrel.
Just curious,(as I have a pretty fair supply of 7828ssc) what does quickload predict the preasure at 100% load density(I'm figuring around 49gr) with Nosler brass, 140gr Partition,CCI250 primer and COL of 3.125"?
I know it's going to be over book, just curious as to how much over book.

What's the actual measured H20 case capacity, level with the case mouth of your Nosler brass?

For my Fieldcraft I loaded up to 42.5 grains of IMR 4350 with a CCI 200 primer/Hornady brass/130 gr. Scirocco and chrono'd them this past Friday. I got an average velocity of 2660. My other load was 45.5 grains of RL 19/CCI 200/Hornady brass/130 gr. Scirocco for an average velocity of 2740 fps. Pretty mild but I'm gonna keep tinkering with it. My 42.5 load, the first day shooting it gave me a .185 group and the RL 19 wasn't too far behind.
The lack of planning on your part does not constitute an emergency on my part!
Looks like 100% case fill is right at guesstimated max. But note that this is C.I.P. maximum of ~55k PSI and not S.A.A.M.I. max of ~51k PSI (46k CUP).

Thanks, that's about what I thought it would look like. Looks like 7828 would be a pretty decent place to start. Have quite a bit left over from loading .270 Win, always worked good there too.
