Hi

I am putting together a table for the Dasher, and would like you guys that are shooting the Dasher to send me your loadings.

I have two Dasher rifles, but would like to compile data for this chambering.

I would like Powder type, projectile used, charge weight, barrel length, and velocity if available.

I am currently using 33grains of Reloader 15 behind a 107MK. Not sure on velocity. This is not a hot load in my Dasher also.

Cheers

Two different Dashers with two brands of barrels. Everything else is the same except the temperature and bullet lot number.

Lapua brass, unturned, neck sized with 0.268" bushing. Berger 105 BT 0.015" into the lands. Russian SRM primers. Chamber has 0.271" neck. Both chambers cut with the same reamer. Powder is Varget from the same lot.

I had a liquid crystal temperature strip on the barrel about 3" in front of the cartridge so the barrel temperature was roughly the same at the start of each five round string. Oehler 35P at 12' from muzzle.

Shilen Select Match SS heavy varmint barrel, 26", Nesika J

Temp 72F

Gn...Mean.ES
32.7 2992 10
32.9 3005 15
33.1 3022 18
33.3 3033 13
33.5 3048 10

Krieger barrel #17 contour, 0.237", 27", trued Remington 700

Temp 85F

Gn...Mean.ES..Group
32.7 2989 12 0.236"
32.9 3015 12 0.172"
33.1 3029 19 0.293"
33.3 3050 10 0.238"
33.5 3063 05 0.309"
33.7 3084 04 0.322"

The group data from the Shilen is meaningless so I didn't include it. Some were in the 0.2"s and some we around an inch as I got a bad lot of Berger 105 BT's (Lot 844) that are absolutely horrid. Once I switched lots it shoots on a par with the Krieger.

The strings were not shot in the sequence shown. I started with the heaviest charge first, then the lightest and back and fourth so the smallest groups for the Krieger would have been the fourth and fifth strings fired. Neither rifle was cleaned from start to finish.

I have some Norma 203-B data around here also that I'll post when/if I find it.

My Dasher load is 33.0gr RL-15, CCI-450, 105 Berger VLD or 107 SMK, Lapua 6BR brass, with the bullets seated 0.010" back from a hard jam into the rifling. Both run right at 3070 FPS. Chamber has a 0.272" no-turn neck. I use a Redding Type S neck die with a 0.268" bushing. Use a Redding body die about every 6 reloads. Went almost 15 reloads before I had to anneal the necks.

My fireforming load (using the false shoulder method) is 32.0gr IMR4895, CCI-450, 107 SMK.

Hope that this helps.

Cheers,

32.0 grains VV N140, 105 Lapua naked bullets +10, CCI 450 primers. I also am having great success with 32.6 gr. of RL15 same otherwise-chrono was 2990 fps. The RL15 load last night at 600 yards had 5 shots into 3.55" and 4 of the shots were 1.625" ,which is great for me. The N140 produced a 5 shot 2.495" group last week. This using a factory stocked (H-S Precision), trued up Remmy with a 26" Lilja barrel-no turn neck, which was chambered by Jerry S. It is a light duty, medium long range prairie dog gun (little varmints watch out) that I am also using to punch paper.

Been fire forming -load and shoot - now with 32.0 grains of RL15 using the Amax jammed.

I have a recent thread with some of this information in it.

Thanks,


Woody
