My SIL uses the Nosler 225 Accubond in his 35 Whelen Improved. At standard whelen speeds, the Accubond is pretty tough, so might be good on elk. However, the Remington 200sp has a good rep on deer and any 2225/250 is poison on elk. I good good groups one time from a Remington 750 Whelen and the Speer hotcor 180gr. Those hot cors are tough. Having said all that, I love to experiment and will try most any bullet, and I find I can determine its usefulness in a box or less, so price is not really an issue. Most any handloader has leftover bullets from several makers/weights/styles, ha. Ain't it fun?
