270wsm and Barnes TTSX powder question

[Harley]

I just made the mistake of ordering multiple boxes of the 130 gn TTSX without first checking the loading data. I had assumed I would use the same IMR 4350 powder that I use with the 130 grain Nosler BT; but Barnes' web site warns that their all copper bullets generate more pressure with lower charges than a conventional copper/lead bullet. Their recommendation is RL-19, but I can't find any of that.

Does anyone have a recipe for the TTSX and IMR 4350; or a recommendation for a different powder with this bullet?

Thanks.

I don't think you'll have an issue with 4350

Since posting my original question, I've learned a lot more about Barnes' bullets and a lot of hunters have reported outstanding external ballistics and terminal performance on whitetail deer with both the TSX BT and the newer TTSX shooting 110 grain bullets rather than the 130 grain that I was used to shooting with the Nosler BT. It is argued that the all-copper bullet, by retaining so much of its original weight, equals or surpasses the killing potential of the heavier composite bullets. An additional bonus would be a flatter long range trajectory.

Since I have a lifetime supply of IMR 4350 on hand AND the TTSX 110 grain bullet is reported to excel with this powder, I just cancelled my original bullet order and substituted the lighter bullet.

We'll see.
