250gr TMZs Versus 290 gr TMZs
 

I have been shooting 290 gr TMZs with pretty good luck but I decided to try some 250 gr TMZs. Unless the 250s shoot more accurately I think I should have stayed with the 290s. I will try them out, hopefully next week. I will print the balistics charts, that came on the box, for both loads. The 290s look superior at all ranges.

From 100 yds on there is no PRACTICLE difference in POI and quite alot more energy from the 290. (higher BC )

I've yet to shoot the Barnes Spit FireTipped MZ sabot so your post is of great interest. I have shot the Barnes Spit Fire Boat tail in 285 and they are just a fantastic shooting projectile. Out of my Knight Disc, I truly feel I could, "with more practice" shoot out to 200 yards with little problem. My big complaint with the Barnes line of bullets is their cost. I just hate to go to a range session and spend $20.00 on the projectiles. Call me cheap, frugal, tight, I don't care. It's the same reason I refuse to shoot powerbelts.

My idea with the Barnes is find you load, record your load, and then hunt with that projectile. I think that tipped Barnes would really work well on large game. What is your opinion of their penetration ability? If they are like the other Barnes line of projectiles, they will sink in deep and hold together..

Im getting ready to order some of the polymer tipped barnes under the Knight brand in 290 grain. They come in 30 packs from Cabelas for 16.99. I am going to try them in my new Revolution and break it in. Its funny that under the barnes name they are the 290 gr. MZ and sell at 20.99 for 24 from the same place. The 290 gr. should make for a good flat shooting heavy hitter. I will post some groups when I get them and can get to the range.

I don't understand why the Knight brand are less expensive either, but they are the ones I buy also. The 290s shot very well for me. I agree that you should work up a load, for hunting, and write it down. They are too expensive to do much target practicing with ( even at $16.95 for 30).

Your posts from earlier this month indicate you are using loose powder... I think FFF.

Hopefully, you are not planning on 150 gr. 777 FFF.... or are you? It's dangerous & against all recommendations from the gun manufacturer & Hodgdon Inc.

115 gr. 777 is the maximum I've ever shot in my Omega. That was one time only at the range. Lately, I've been using 90 grains 777 FFF-- good to 150 yards. Should my present hunting distances change & allow me 200 yards, I then use 105 gr. 777 FFF.... giving me roughly a 9" drop at 200.

NO! I would never use 150 grs of 777 loose powder. Those balistics are 150 grs of 777 PELLETS. I guess I should have made that more clear. I use a MAX of 120 grs. of loose 777 in my Omega.
