I used 2400 for supersonic loads. VVN110 or H110 should be fine also. I would start at 16 grains of 2400.

Well, the Russian addition of Snipe's thread has begun. I just got my order today and will try to test some subsonic loads this weekend. However, don't let me stop anyone else testing at sub velocities.

On the other end of the velocity spectrum, I also loaded a few full power loads by utilizing some WOLF factory cartridges for my cases and powder.

I know that I won't get match accuracy, or the best velocity, with the smaller bullets through my Rem 799's barrel but it's gonna be fun none the less!

It probably won't work quite as well, since you will be working with a bit more case capacity, but you may be able to use heavier (150-180 gr.) bullets seated deep to take up some of the volume. I would start with a 123 grain bullet at normal seating depth with a case full and work down from there. I would imagine you will be around 1300 fps with a full case. Somebody with quickload may be able to verify that.

Snipe, I'm not really worried about the results other than to see what will happen. I'm one of those guys who's "what if" butten has been pressed so many times it's stuck.:grin:

My normal subs are 174gr FMJBT's (loaded forward or backward) over 6gr of trailboss but I have gone as heavy as 220gr for testing over 6gr of TB with positive results.

I might also add I will be testing some Hornady 86gr semi jacketed round nose (.308) as well.

Have you had any luck hunting any varmints with your loads yet?

I haven't had the opportunity to shoot anything with the 90 XTP's, but I did shoot a pig with a 208 A-max. It poked a 30 caliber hole clean through, but still, the pig was dead within 150 yards or so. I'm done shooting subsonics though, because my barrel does not stabilize them, and I had another baffle strike recently. The only thing I had been shooting that day was the 90 XTP's, so apparently NOTHING works in my barrel. I'll just stick to supersonics until I can afford another barrel someday.

:eek: Hope there wasn't too much damage!

QuickLoad info:

1.562" COL gets you equal depth of seating and bullet diameter (.309) @1.355" trim length

16" barrel (bolt action assumed)

Alliant 2400 @ 16gns (96% case capacity) nets ~97% burn @ ~2400 fps
Hodgdon H110 @ 18.8gns (99% case capacity) nets ~91% burn @ ~2350 fps
Hodgdon Lil'Gun @ 18.4gns (100% case capacity) nets ~97% burn @ ~2400

Has anyone else had any experience shooting any heavier bullets over Trailboss? What velocities were you getting? I have tried the 178gr A-max over 6.0gr's with good results.

I shoot both 174 and 220gr Hornady over 6gr of TB. I need to re test them over the chrony but if I recall the 220 was under 1000fps and the 174 was a tad over 1000fps. Please don't quote me on these since I have lost (or misplaced) the results.

My favorite load is the 174 loaded backwards. I have a few with the boat tail drilled to make a nice HP that I want to test this summer but the flat point works great as-is.

I can not get that much TB in a case with the heavy bullets....
