Not running one, but 50 fps slower than 26” is a good rough estimate. Sent from my iPhone using Tapatalk

Norma brass (once fired factory norma) 215GM RL26 - 48gr Redding bushing die .290 for .001 tension Redding micrometer seating die 2.898 oal which is 0.050 off lands (and incidentally the farthest the bullet can be seated while keeping the BT below the neck) Tikka T3x CTR, 20” 2740 ish fps. No...

These are in order from 47.1 to 48. 48 was best, 47.7 worst. Sent from my iPhone using Tapatalk

Here is a little data from the initial RL26 workup about a month ago. 2.898 aol 2.250 comp 0.050 off the lands. 143eldx 20” bbl That’s as close as i can get to lands, boattail just past the shoulder junction. (all of it). Interestingly, these are pretty dang close to the QL DrMike provided...

Awesome! Thank you. I’ll report back on actuals for future reference. Was thinking a little more was there from the H4350 and RL16. But i suppose it’s pretty close considering the 20” bbl. Looks like i can try a drop tube on the 26, as there is still some room to go. Again, thanks for...

I don’t have brass capacity. Norma Brass Fed215GM 143 eldx 20” Bbl H4350, RL26, RL16 are the powders i’m looking at. 48 gr of RL26 magneto’d at 2739 avg. Very, very lightly compressed. A kernel break every few loads Redding micrometer seating dies, say not to compress, so..looking for...

20” Bbl, 48.0 gr of RL26, very slightly compressed at 2.898 coal. (could just ever so slightly hear a kernel or two crack) 143eldx. 2740fps. Sub moa. (only 3 shots, but 1/2”) 47.4 was at 2708, no compression. Both single digit sd, es under 20. 0.050 off lands. 47.7gr accuracy was...

Can i get a reality check. 338 RUM Nos 1x brass, 113.3 h20 cap 3.72 coal ( This is still about 0.115 off the lands) 300 gr SMK 26” bbl Actual, per magnetospeed (3 shots per) 91.5 gr RETUMBO: 2776 sd 2, es 5 92.5 gr RETUMBO: 2787 sd 16, es 30 93.5 gr RETUMBO: 2820 sd 13, es 26 94.5 gr...

I was interested to see what some 1x Rem factory loaded brass looked like. Measured 10, 273.4 gr. Measured 3 loaded w/h20, 387.4 Net cap = 114. They were also in the 2.740 - 2.742 range. So, Nosler brass SD was like 0.4 grains (for 12). Rem was SD 1.1 for 10. Nosler was 15 gr (5.5%)heavier...

Oops, make that 111.96 with oxygenated water. 113.3 with deoxygenated this AM. Brass is 2.740 - 2.742 after 1 firing. All of the new Nosler brass is "short" at 2.736 ish to start with. At least the 200 i have were. Sent from my iPhone using Tapatalk

Haha, Thanks! I went through the process, closely, prior to reading this. So, oxygenated water.. Weighed 12 cases (the 7977 cases). Avg 288.37 gr. Picked 3 cases that weighed 288.4. Filled and re-weighed those 3. avg 400.33 net capacity = 113.96. I'll re-do in the AM i guess...

It was last saturday i believe it was around 50. What's the process for getting capacity? Weigh spent case, fill with water, weigh again? (I guess i answered my own question there) Thanks for the help. I'll see if i can sneak away to get capacity this weekend! Sent from my iPhone using...

Oh, and to be clear, the Rl26 load was shot in a different (his) gun. Sent from my iPhone using Tapatalk

I am looking at 210 TTSX with RL26 and IMR 7977. Nosler Brass (not sure on h20 capacity) Fed 215GM 3.736 oal (0.10 off lands) 26" bbl I did load (and shoot over magnetospeed) some 7977, so i'm interested to see what the predictions look like in comparison. Thank you, Sent from my iPhone...

Thanks gentlemen. I plan on trying some other powders and taking another stab at the 250 AB's over the winter. I have some 7977 and RL22. A friend has shot 210's with RL22 for years. 225 E-tip looks very intriguing, but it has proven elusive to date. JD338 - What's your oal? was 98.6 highly...

Newby questions Preface by saying I pulled some info from JD338 and DrMike in getting a starting point for 2 loads. 1. 250 AB/Retumbo 2. 225 TTSX/Retumbo (Pulled this from #3 manual also) Nosler Brass, 215GM Both were loaded to 3.72 oal. Lands are +\- 3.8 for both 250 ab and 225 TTSX...
