At 2:26 you said FIFTYthree grains.. i said..wait…WHAT?!? I’m glad you corrected that in the text. And kids at home… THAT is why you work up to loads that you hear about on the interwebs.
I just went today to the range, I have a ruger American hunter in 6.5 creedmoor, arken 6x14 and 22" barrel. I noticed that this powder moves in and out of the node very quickly. I believe it was 43.5gn that shot a .324 group at 100 yards. And two more different lower charges almost matched it.
I had a great load with superformance and the 147 ELDM..I was concerned with temp stability so I switched to staiball 6.5 and had great luck with 130 and 140 grain projectiles.
@@mattsreloadingbench your load of 43 grains pretty much matches mine exactly also..I like the validation because I'm relatively new to reloading but I jumped into the hobby full go..
I've mastered 6.5 grendel out of a 20" Howa bolt action..it doesn't have the power of the creed but from 85gr to 120 gr I've worked up awesome loads.its my favorite 6.5.
43.1 StaBall 65 with the 143 ELD-X's grouped 5 shots, into, a 5/8th inch wide x .175 High group at, a COAL of 2.835" for me, at,. 2,725 FPS ,.. I'm Very pleased !
I use the same combo in my t3x. Your results may differ, but I had a very similar experience regarding accuracy being good and SD/ES being meh w lower charges. Then I went up into 44gr territory. Gun shoots consistent 0.4 moa with an SD around 5 fps. I also set the neck ID to 0.2635 (neck tension of 0.0015) which increased speed and improved SD/ES.
Great question! Thus far, after having 2 PRCs and 2 Creedmoors, I am finding that the Creedmoor is more accurate, but the PRC is flatter shooting. I am finding that with the PRC, I am getting better results at lower charge ranges where with the Creedmoor I am getting better results at the max charge area. I am starting to notice the the heavy bullets are not performing as well when you kick up the muzzle velocities.
Just found Stabal in stock @ lcl Cabelas. Want to use it for a mule deer load in my 6.5 CM; your vid is _timely_. My bullets are Hbn treated. Hope to get similar velocities in my 22in 5R TC Compass barrel with Peterson brass & Fed 210M primers. Sunscribed!
I plan on using the 6.5 Staball in my begara 6.5 creedmore with 130 grain scirocco moly coated what is a starting load you would recommend Norma large rifle brass and CCI 200 primers
I wouldn't be able to tell you any starting point specifically. Look in a loading manual and see what max is. Then back off up to 10% and work your way up. I personally have never used a 130gr. The lightest bullet I have loaded for 6.5 Creedmoor is the Barnes 140gr. Thanks for watching and have fun with the process!
Staball like Superformance are not like your usual powders. Not by charge, density or velocity. You can easily get 2850 fps. Try for 2800fps with 44.2 and COAL of 2.800 (95%). If you are getting an erratic plateau chart your density is too low. Ex. fill the case (with bullet) to 85% and you get a chart like what you see. The higher the case fill %, the longer and flatter the plateau will be. You should be seeing a plateau of +/- 0.5 gn (full 1 grain spread).
Matt, 2 questions here: 1)Have you considered playing with cartridge length at 43.1 to see if the group shrinks up? Bcuz that SD and ES is gonna be nice past 1000 yards. 2) at 0.020" off the lands, what is the COAL? Can u even fit those in the magazine or do u have to single load them. My AR10 6.5 CM is like 2.230 to the lands and the longest i can load 147's into a steel duramag is like 2.218 to the ogive. Thanks for the video!
I can definitely look at that some time in the future. It is too long for a magazine. I don't take the mag into consideration for my precision rifles. I single feed them. But for my hunting rifles, I try to keep everything as close to published COAL.
I have not personally noticed a difference in performance. But I do think that the primer pockets hold up better over more reloads of that piece of brass. I believe that is because of the fact that there is more brass in the base due to the primer pocket being smaller. It can hold up to slightly higher pressures also.
The recipe = brass / primer / powder and charge / bullet including seating depth. Results = 5 shot group sizes at 100 and 500 yds / Average Muzzle Velocity / SD / ES. Shooting Date and weather info of when the shot data was created. Weather info = Date / time of day / elevation / humidity / Atmospheric pressure. Every time I shoot, I take notes of all of this in a notebook and apply it to my final recipe book.
I would have to say that the only advantage to PRC over Creedmoor is that you can achieve higher velocities. This results in a flatter shooting round. Also, the 6.5 PRC has a harder impact at a little more distance than the Creedmoor because of this. As far a group sizes, that is all dependent on the quality of the rifle, scope, ammunition and the shooter. Now, from my personal experiences, I am able to get the following results with my rifles .5 MOA with my Tikka 6.5 Creedmoor .3 MOA with my RPR 6.5 Creedmoor .2 MOA with my Seekins Havak HIT 6.5 PRC .75 MOA with my Christensen 6.5 PRC *** not happy with results *** I love all of these except my Christensen. It was one of the hardest rifles to hand load for that I have ever had. Heavy guns make small groups easier to obtain from my experience.
Also you are too close to the lands. Hornady and Hodgdon recommend 2.800 for a reason. Current practice is no closer than 50 thou off the lands. Previous 20 thou practice have been erroneous. This is also why your velocities are anemic. With 43.7 you should be at about 2775fps. Your case fill % is low at very low 92%.
