Re: Looking for a new elk gun
LTLR, I got my Sako 85 Finnlight 300 WSM this past spring to replace my aging 7mm RM that was loosing accuracy. I wanted something a little bigger like a 300 mag and after doing some shopping I went with the 300 WSM. This was before I had any interest in LR or else I would have picked a different plattform and probably a different cartridge. I think the 300 WSM is a good cart though, I like the case design and it allows for shorter more carryable barrels/rifles for shooting and seems be a very accurate cart as well. However, with my setup, accuracy is terrible and I sent the rifle back to the company, via the dealer to get it evaluated and possibly replaced. I'm not sure if it's the rifle or the Optilock rings? I put a 2 lb Nightforce on it, and with that cart it probably really stresses those rings. So I do plan on getting a Sendero 300 RUM wich is more inline with LR. Scoped out, it will come in at about 11 lbs, a little heavy for carrying but I should manage for a few more years.
3419 fps out of a 24" barrel is incredible. That's about 150 fps more than some charts show for a 150 gr bullet. You might look at the 150 E-Tips, as they are also a monometal bullet with a better BC than the TTSX (.498 vs .420) Other advantages are they are made from a tougher guilded metal and retain their petals at higher velocities better than the TSX and probably foul less too.
I haven't tried any 150 bullets out of my 300 WSM yet, because I didn't think I could achieve the the velocity you are getting and I didn't want to waste anymore time loading or shooting this rifle than I had too, to get me thrugh hunting season. I did try the 168 TTSX's and was only getting about 30 fps more with them over the 180's at max loads. Interestingly, the 180 E-Tips maxed at 66 gr of H4350 while the 168 TTSX's maxed at 65.5 gr of H4350 which I found a little surprisng because the E-Tips had more weight and bearing surface. If I could get 3420 fps out of the 150 E-Tips, I could get bout 150 yds more performance than I am with the 180's @ 3020 fps. BTW, 3000 fps is about what most charts show for a 180 bullet in 300 WSM. My personal approach to choosing hunting limits for a particular bullet/load is minimum opening velocity and about 40 lb ft of momentum for penetration for elk, and just opening performance for deer.
I would like to keep this rifle or it's replacement if I can get it to shoot, but with construction (my work) the way it is, I may have to choose between the WSM and the RUM.
You can get the E-Tip BC info off the Nosler site, under the store section.
