a while back i found that the 290 TEZ w/ 110 grains blackhorn 209 was a very accurate load. I always use the regular CCI 209 w/ an o-ring under the primer. I dont drill out my plug it just fits nicely. This I was advised by Keith at western powders to do so I've done this ever since w/ never a problem. I have not taken a bear or anything w/ this load but I am or have read enough reports that indicate great performance as Barnes reputation stands strong. I have found that the .452 300 deep curl is all one ever needs out to 200 yards and the price is more than fair. Sabotloader,and a few others on this forum are very fond of this bullet and if you check back in the records here you will find a lot of reports from these men who have done extensive research w/ the performance of the deep curl. Hope you find this helpful. Take care.
