.260 loads and powder choice

[Lightflight]

1:8 twist Mcgowan 26"
140 amax bullet
0.010" off lands
44gr IMR4350 barrely compressed load
Lapua brass
CCI br2 primer
2780fps when its in the 80's and 26.14 inHG
No signs of pressure at all.
seems like most people settle around 44.5g
I worked up to 44gr obviously and so should you...obviously

I only have 60 rds down the tube, but so far 3/4" @ 100 and 1/2 MOA at 450yrds

.5 moa at 450 is pretty slick! I have a pound of imr4350 and a couple of RL 17 so I hope to find a faster load. I started w/ Varget mainly because it has made tight groups in everything I have ever put it in. I am sure this is a pretty mild load but these were shots 16-20 on this barrel. I have a couple hundred 140 amax to play with.:)

I have tried H4350, Varget, and RL17, and RL19. I ended up settling on two loads...H4350 with 120 grain TTSX for a hunting load, and RL19 with 120 gr Nosler BTs for range and targets. I don't have anywhere yet to shoot past about 400yds, so the 120s work fine for me.

H4350 is about the same as mainstream pistol powders here, nonexistent!
I've been messing with Varget, R17 and H100V.
So far R17 has been the ticket.
41.5 R17 with hornandy 140 bthp gets me 2800 and very good SD/ES numbers and easy sub MOA 10 shot groups in a 26" barrel.
Varget obviously works well and H100V seems to show great promise.

I just stumbled across this post.

With my 260 Rem McGowen 24" 1:8 barrel I am shooting 42.8gr RL-17, Lapua Brass, CCI BR-2 primers, and A-Max 140s at 2875-2885 FPS at 1/2 MOA. So far I have qualified out to 1200 yds at this point (that's the limit of our range).

Previously my load was 43.0gr of H4350 @2825 FPS, but I went almost a year without seeing any H4350 so I switched to RL-17.

44.0gr RL-17 seems REAL HOT in a Rem 260.
