A little tight, feel similar to my Lyman GPH and Hornady Great Plains bullets, thought that was normal. I’m pretty ignorant when it comes to sabots. Are the Harvester Crushribs easier? The XTP’s I’m using measure .430, while the Speers measure .429, figured that would help a little also.
Yes, they will load a bit easier. Usually the crushribs are a good fit for T/C bores too. Next step up is the regular Harvester sabots. The sabots you are using now are about .002-.003 larger when loaded. They will probably feel even tighter when you use a longer 300gr bullet. Its really hard to beat that 300gr DeepCurl for the money. 300gr XTP non mag is fine but the Speer is a better bullet.
