This is my third year drive hunting wild boar and roebuck deer with a Win94 (classic 20inch barrel) in 444M.
I have stopped using the Rem factory for reloads with a 265gr Hornady bullet on top of N130 powder (max load from Vithavuori tables)
I get the same speed with these reloads than the Rem factory (680m/s, 2300fps in the Win 94) so 10% more energy as the bullet is that much heavier.
Roebuck are rather small and light (20-30Kg, ~65lbs) so anything will drop them. Nevertheless, I noticed on the few I shot with the Rem, expansion was dramatic and starting immediately. The entry hole was almost as big as the exit.
Whitetail are a tad bigger and stronger but for sure the Rem factory will be fine.
Wild boars are an other story. They are very strong and I would not use either the Rem factory or any reloads with pistol bullets or even the 270 Speer. I tried the 270 Speer but the jacket is very thin and they expand too early and violently.
Sofar I dropped 3 small boars (50kg, 110lbs), two in the heart area, bullet went throug and in one case broke the shoulder and one this weekend in the neck, massive damage inside but a small bullet size exit hole with almost no blood while the entry hole was bleeding.
I came to the conclusion that even the Hornady bullet expands too early.
I could try heavier bullet but OAL in the Win is limited and I would not like a bullet that is too slow and therfore to have to give more lead.
I wonder what would happen with a very big boar hit in the shoulder area and really think a tougher bullet would be needed. I am even considering FMJ used for silhouette.
From a stand or stalking, I use a Sako in 300W and this summer had to finish one (110kg, 240lbs) that was still alive after having been hit in the shoulder that was smashed by a 180gr Nosler partition I recovered against the backbone it failed to break.
I you know stronger bullet than the Hornady, let me know. I wrote them asking if they plan to manufacture 44 bullets using their Interbond process but did not get an anwer yet.
I wish to share info with anyone hunting big wild boar too.
