So I've been working on some 6.5 grendel loads and I've got a pretty decent one. It is at max charge, and I don't see any pressure sign.
I'm tempted to up the charge a .1 or .2 gn and see how it goes. So have any of you loaded past max? Usually I see something, cratered primers or ejector marks.
Book limits are set by lawyers - let the gun, primers, cases and velocity tell you what “max” is.
Load past book max all the time (223 with 77/80s, 6 Dasher, 6.5 Creedmoor, 260, 308). Never an issue.
I did have one 260 round with W760 that was under book max but actually WAY over due to powder temp sensitivity (warm day/direct sunlight), but that’s for another time.
My groups got much tighter the higher the charge. Starting out at mid charge yielded a 3" at 50y group and by the time I hit max, there were multiple shots in the same hole. That is certainly good enough. Occasional flyers have me wondering if pushing it a bit more would pull those last few stragglers in.

Truth. I seek more skill and to make better arrows as well. If I have found the limit of this particular load...so be it.My guess is if you are putting shots in the same hole at max, any flyers are the indians shooting skill, not the arrow.

I went over .1gr using 8208 xbr. It got the best groups with my 123gr sst bullets.So I've been working on some 6.5 grendel loads and I've got a pretty decent one. It is at max charge, and I don't see any pressure sign.

I dont let velocity tell me anything about over pressure.
Is that not the intended purpose of loading data overcharging?
