My truck gun is a .243 I carry it for coyotes(not my go to rifle for deer) but sometimes I have to use it on deer as it is all I have with me. So what are your best loads for deer, not theory but actual field experience. Thanks

Remington 100 gr CoreLokt in factory ammo and handloads work fine. These days I handload 100 gr Nosler Partitions over IMR4350.

100 grain Hornady interlock spire points. RL22 works well for me.

42 grns IMR 4350 100 grn Sierra Pro Hunter

Speer 105 grain SP, 43.5 grains of H 414....

Might be a tad hot... so work up....

3250 fps, out of a 22 inch barrel and very accurate in my Ruger and Winchester 243s....

Will penetrate as well as a partition any day....

cheers

Your truck wouldn't haul the whitetail that I have taken or seen taken with the 95 or 100 gr. partition. 33 gr. of IMR3031 has been an accurate though mild load in several rifles. If you want more velocity 4350 works good but the deer will never know it.

I guess I'm the odd man out. One of my 243's likes the 85 grain Partition with 42 grains of IMR4064 for whitetail and antelope. The other one hasn't shot a big game bullet out of it that I know of (all varmint bullets).

IMR-4350 w/ Hornady 95 gr. SST

Sierra 85 gr HPBT thru the ribs...it's magic!!

hard luck I use H 4350 and A 100gr. speer bullet fed primer.

48 gr. 7828 and speer 90 gr. hot core 3220fps. out of a ruger ultra light wieght 181/2 in barrel
