QL Request.25-06

[Ridley75]

I probably missed it with my search but would someone mind running a QL for .25-06, RL19 and IMR 4831, Barnes TTSX, 100grn, once fired Hornady brass (I don't have the H2O volume). I am currently running book COAL at 3.080".

Respectfully
Justin

 

[Guy Miner]

I can't help with Quickload, but you might also consider IMR and H 4350. Both are time tested, well proven powders for the 100 gr bullets in the .25-06, with 3340 - 3350 fps and excellent accuracy on tap.

FWIW, Guy

Guy, I have search high and low for 4350 with no luck but your not the first to recommend it however I do appreciate your recommendation.

Tack, thanks for the run. I'll see what I can come up with.

 

[boomer68]

If you can find some, Retumbo is your huckleberry with the 25/06

 

[Guy Miner]

If you can find some, Retumbo is your huckleberry with the 25/06

That's what I use with the 115 gr bullets! YES!

Have stayed with H4350 for the few times I use 100's. IMR 4350 has just as good a reputation and is likely easier to find.

What the heck happened with the supply of H4350? It was common as all get out, and then virtually vanished!

[taylorce1]

RL22 isn't half bad either in the .25-06!

 

[Ridley75]

I can get RL22 and Retumbo so maybe I'll look into those as well.

The QL numbers match Barnes' data so I think I just have a slow, but accurate barrel. I know that book values are optimistic but I am running 150 fps+ below them in a 24" barrel. Now that Ca will be 100% copper soon I would like some more speed to insure expansion.

 

[SJB358]

Had real good luck with RL19, 22, 25, 26, Retumbo, and H4831SX in the 25-06. If you can get your hands on some RL22 I'd think you should be able to get a good combo going. RL26 with 100 grain ETips was very fast in my rifle.

 

[Billyram]

Back when I had my 25-06 there wasn't as many powders around for reloaders but the ones that performed well were 4350 and 4831. My Hart barreled 25-06 would put 5 of just about any 100gr bullet under 1/2" @ 100yds. at close to 3400fps. This load worked well on the small deer we have around here but a good bit of the time there would be no exit so I switched to heaver bullets . 117 gr and 120 gr bullets weren't quite as accurate but the 120gr solid base would shoot near 1/2" and worked well on deer. If a deer ran you wouldn't have any trouble finding it. I still have a box of these.

[Ridley75]

To add another question to the mix, I've been using CCI 200 primers but noticed that Barnes used Federal 210. Does anyone think that could contribute to my speed loss? If so what would you recommend?

 

[Guy Miner]

Typically I use Federal match primers, but I don't think there would be any significant change in velocity.

 

[DrMike]

Brisance with either CCI200 or F210 would be so close as to be insignificant in ignition of powders.

 

[Ridley75]

Thanks Guy and Dr Mike. I've got 1,000 of the CCI primers so might as well use them. Last Friday I grabbed a lb of RL 22 and am going to try and put some test loads together before the wife and daughter get home this evening.

Ridley,
I don't know what part of California you're in, here in Tx we have pretty good swings in temps from winter to summer. For me, RL19 gave good accuracy and decent speeds at 40. These locked up the bolt at 85.

Ridley,

Annually our temps range from height 20s (winter) to over 100 (summer).

With that said I went back and compared my chrono data for 90 grain Hornady GMX with imr 4831 against book and it was spot on. Accuracy wasn't too bad, about an inch. I think that I can improve that by playing with seating depth. On the other hand I've got loads with RL22 and 100 grain TTSX waiting on my bench to test. I really want the TTSX to work.
