Title: 6.5 Creedmore velocities
Post by: Hilltop123 on November 25, 2018, 10:31:27 AM: Well I took the plunge, purchased a Creedmore. So I have been playing around with some loads with ELD-X 143gr and I am no where close to published velocities. I attribute a percentage of this to a new barrel and not finding the right powder. What are you guys getting for velocities and what powder are you using and with what bullet weight? Thank in advance.

No issues for me

Post by: Bofire on November 25, 2018, 04:32:12 PM: I have never loaded the 6.5 but in 50 years of reloading I have NEVER gotten the velocity the book said. In testing of factory loads I have NEVER gotten the velocity published.

Title: Re: 6.5 Creedmore velocities
Post by: Hilltop123 on November 25, 2018, 06:10:54 PM: I'm using H4350, 41.5 gr, listed max. Book shows an approximate velocity of 2700 fps, but I was getting 2597 fps. I thought this was way outside the window, even for estimated velocity. Anyway I wass just curious on others results.

Post by: Karl Blanchard on November 25, 2018, 06:18:44 PM: Thing you gotta take into account is barrel length. Most times the test barrel is much longer than your average factory tube.

Post by: Hilltop123 on November 25, 2018, 06:20:30 PM: 24" same as was used for the data collection
Title: Re: 6.5 Creedmore velocities
Post by: CaNINE on November 25, 2018, 06:25:11 PM: I’ve pushed into the 2850 range with a 26” barrel. Accuracy is best at 2750. H4350.

I would normally agree, however the Hornady ammo im using in my 6.5 said 2700. Ive shot it thru the chrono 6 times and everyone was +/- 10 fps. I was amazed

Post by: BULLBLASTER on November 25, 2018, 06:39:24 PM: Chamber differences can have a large impact on velocity and pressure as well.

Post by: b23 on November 25, 2018, 06:40:38 PM: Hilltop123, are you loading these to the book OAL of 2.800 or a bit longer? Seating depth will affect velocity. QL shows 2680fps with your load specs at book OAL of 2.800 so you really aren't that far off.

If you are looking for better velocity RL26 will be the best powder to use, especially with the heavy bullets.

Post by: Hilltop123 on November 25, 2018, 06:50:02 PM: Yes loading to a coal of 2.80, at the moment
Title: Re: 6.5 Creedmore velocities
Post by: jrebel on November 25, 2018, 09:00:44 PM: rl 17 was super temp sensitive for me.....I won't use it. I ended up using H4350 pushing 140 grain accubonds out of my savage stealth and am getting 2830 fps. (I think....I will double check tomorrow with my books).
Title: Re: 6.5 Creedmore velocities
Post by: jrebel on November 25, 2018, 09:07:37 PM: Might also add that accuracy trumps velocity 100% of the time in my books.
Title: Re: 6.5 Creedmore velocities
Post by: jasnt on November 26, 2018, 06:15:05 AM: I too found re17 to be way temp sensitive. Be carful with loads worked up in cold weather cause when it warms up you may be over preasure
Title: Re: 6.5 Creedmore velocities
Post by: b23 on November 26, 2018, 09:25:16 AM: My experience with RL17 has been it's one of those quirky powders that gives you little to no warning before you're into over pressure. It'll go along and give no pressure sign/s then you make one tiny little increase and all of a sudden you've got all kinds of pressure.

I'm not a huge fan of Alliant powders but I am a big fan of RL26 and it is quickly becoming "the" powder of choice in a lot of different medium-medium large size cases, with the 6.5 Creed and 260Rem being a couple of them it works very well in. Another powder you could give a try is RL16, it's one of Alliant's new temp stable powders. I'm using RL16 in my 20-250 and it's working very well in that. You can look on Alliant Powder website to get a starting point. They don't list a load for the 143 ELD-X but they do for the 142 SMK so you should be safe using that load as a starting point by dropping a grain or two and working up from there.

Post by: rudysts on November 28, 2018, 09:26:36 AM: I am getting 2875 fps with a 140 Berger VLD using RL16 and Lapua brass out of a 26 inch barrel.
RL16 might be worth a try. the charge weight is about a half grain below max (Alliant website) for 140 bullets.
