Home Forums Reloading Big Game Rifles 105 amax in 243 10 twist

My daughter's 20" howa youth stoked with rl26 poked them into some of the best groups I've ever shot. THere's been some question if they will stabilize. They will.

You guys are killing me with this RL 26/243 talk.

You guys are killing me with this RL 26/243 talk. I had no clue this would work as well as everyone says.

What's your elevation?

I have so much RL17 hoarded......I do want to try 26! Afraid I'll make the switch.

What kinda velocity are you getting with 105s using RL26?

3150 was quite accurate.

How many grains are you using to get this speed

3150 fps with a 20" barrel?! Impressive.

I ran from 47 to 49

Tried RL26 with the Hornady 105gr HPBT Match, loaded up to 49.5grs of RL26, accuracy was good if not alittle better than RL19, but we're talking groups in the 2's so no use worrying about accuracy and go for the horse power since the groups were the same. Couldn't get the velocity that I do with RL19, with RL26 I got 3252fps and with RL19 I got 3387fps. This was out of a 26" Shilen Select Match barrel.

At 3000' elevation, my 10 twist Kimber won't stabilize that bullet at 3120 fps. It has been AI'ed.

Groups in the .02s? Impressive.

Sure aint the case around here.

Groups in the .02s? Impressive.

I ment 2's, .02 would be impressive

Well I'm impressed if you are getting 3387 with a 105 grain bullet... are we talking 243? or the Ackley version... or a 6mm AI Rem, or 6/06 240 Weatherby?

we are talking 243 win aren't we? 26" shilen select match,this is ai fast barrel, backup rifle with same barrel using same load goes 3327fps for a average, RL19 and the 243 is a match made in heaven, I use it in all my 243 and I have alot of them. Really sends the Barnes 80gr TTSX speeding down range too

Well Gemby,

That is pretty darn impressive...

I know RL 19 does wonders in my 6 mm Remington...

You've lead me onto something I'm going to have to pay more attention to.... nice to learn something new..

I don't have any AI'ed rifle chamberings... but this is certainly fun stuff waiting to have....

thanks for posting!!!

Seafire I was impressed at 3150 out of a high country's 20" barrel with RL26 that I had to buy some to try it hoping I could reach 3500fps but it went the other way.

I'm a big fan of RL19 using it in my 243, 25-06, 7mm08, 30-06, 300 win mag, 300 wby, 338 win mag, 340 wby. always gave me good accuracy and velocity. For the heck of it I'm going to try it in a 223 one of these days.

had a gentleman on here contact me about his 243 not being able to shoot less than 1", he asked me if I had a good load for the Barnes 80gr TTSX and I told him what all my 243's use which was RL19. he got back to me after loading some of my powder charge recommendation up and he said he shot a 3/8" group.

At 100' elevation, 105 gr. Scenars would not stabilize in my 10 twist .240 Wby. and at even higher velocity.

Velocity helps, but IME, it's a weak substitute for twist.

DF

all my barrels are 8 twist but wanted to comment on RL26 to see if I could squeeze out more velocity over RL19. with high county getting 3150 out of a 20" barrel, i was hoping I could get 3450 or 3500fps out of a 26" barrel.

3400 is doable with a 28" or longer barrel so you should be able to get close or in the 3350 ball park at least. I stopped at 3150 in a 24" barrel as accuracy was good and I was at book max and no need to push it harder.

My 22" Ruger 243 is accurate with 47 Gr of RL 26, CCI 200 primer, RP Case, 105 Gr Horn. A Max, 3063 FPS.

Any higher loads and it shows ejector marks.

Reduced and accuracy goes.

Picked up some RL 19 yesterday.... been out of it for a while...

Will be trying it soon...

now if I can just find some of those new 108 grain ELD-M from Hornady and those 110 grain Match HPs from Sierra...

gotta try those in my 6mm Rem..... as it has the one in 7 twist...

I love the Hornady 105gr HPBT the best, my barrels don't shoot the a-max near as good as the HP's, that's OK as the bc is higher too

Tag

to the gills.. and then just level off the top and seat your bullet..

just funnin' but pretty close to what I've done with the 243 and RL 26..
with 105 grain bullets....

try a new 108 grain Hornady ELD Match with that 1 in 10 twist..

minute of Sling Shot results...at 50 yds...

im running 47.5grs of RL19
