How fast were you able to push the 100 grainers?

Disappointed by my most recent chrono session. I tried CCI#41 primers, 31.5 grains of H322, and a 70 grain BK. Velocity was only 3060 but vel was very uniform!! Looking at the case head, saw some smears so probably cannot go any higher.
100 grain Hornady spitzer, 32 grains LR, and CCI#41 primer, got me average of 2707 with some smears. The primers are difficult to seat so they flatten some before firing, they still appear to be right at the stopping point.
Was going to try some more but rain appeared.
My velocities at an earlier session was higher for some reason but with 7 1/2 primers. Will revisit this again

I got higher velocities with the 7 1/2's also. Something to note ---- I got my highest velocity with Sierra 100 gr. boatails. They were faster than the prohunters, hornady and swifts. Something to do with the bullet contact surface in the bore I suspect.

Also, I run a heavy buffer system by tubbs. That got rid of my swipes.

I will give this a try but I am not technically inclined so I may just confuse you more.
A swipe occurs when the bolt tries to turn and unlock before the pressure has dropped sufficiently for the case to release its grip on the chamber.
This can be a high pressure issue or a timing issue. Timing issues seem to occur more often in carbine or sometimes midlength rifles.
Timing issues occur when the peak pressure is not excessive but the pressure arriving at the bolt occurs too early in the progressive ignition sequence.
Anyway feel free to correct me if I am wrong!
Greg

I am returning to Rem 7 1/2s. I found no advantage to the higher priced #41's and like you lost velocity.
I have a bunch of BN coated bullets to shoot but they are with the #41s. I will shoot them just for a bit more history of how they work versus the Remmys.

someone on here posted the max fps he obtained as 2900. But....he did not list the powder or charge weight. Screen name may be Siringo if that is any help. He also may have some info on heavier bullets as I think that is his thing, which may not be a bad thing to consider!
Hope this helps!
Greg

6mmDTI 22 inch barrel 1 in 10 . So far I have tried H4895 Fed primers 205M with OAL of 2.260 With very good results. This is the load that I took a deer with this year. I tried .010 , .020 and .030 off the lands and .020 is the best. This load is also showing signs of pressure. First time with Varget 29gr is the best and 29.2 showed some flatting of the primer.
